Engineering Manager | Remote (North America) | $180k-$230k Team grew fast and organically — lots of talented engineers, no shared process yet. This role turns that into a scalable, high-throughput org. Reports to VP of Eng (who owns architecture/vision); you own execution, delivery, and people for ~10 distributed engineers (US/Canada/EU/UK/China). ~90% people management, not player-coach. You'll own sprint commitments and release cycles, run 1:1s and coaching, remove cross-team roadblocks, own incident response and on-call, and track/improve DORA metrics. Also expected to hold a high bar — direct conversations on underperformance, PIP-first, exit if needed — while keeping the culture kind and caring. Need: 2+ yrs directly managing ~10-person eng teams, distributed/async experience, strong enough technically to run code reviews and push back on estimates (not coding day-to-day), track record raising delivery throughput at a high-growth company. Nice to have: big-company process background (Google/Meta/Salesforce-style) mixed with startup speed, and logistics/supply chain/e-commerce domain exposure.

Prior Labs | Berlin / Freiburg / NYC | ONSITE | Full-time | Multiple Roles | https://priorlabs.ai/ Deep learning transformed text and images but mostly skipped tables, even though they're behind most clinical trials, financial models, and scientific experiments. The reason is structural: no natural sequence, no spatial structure, no shared vocabulary across datasets, so the architectures and scaling laws behind LLMs don't transfer. We're building the foundation-model approach for tabular data. We started with TabPFN. v2 was published in Nature and set a new state of the art on tabular benchmarks; since release we've scaled capabilities ~20x and crossed 3M+ downloads and 7.5k+ GitHub stars. The hard problems are still open: scaling to millions of rows, low-latency inference, new data modalities, and the infrastructure to run all of it in production. Open roles: - Senior ML Infrastructure Engineer - ML Engineer, Cloud Platform - Full Stack Engineer, ML Platform - Research Scientist, Foundation Model - Applied Scientist - Forward Deployed ML Engineer - Developer Relations Engineer - AE 35-person team with backgrounds from Google, G-Research, Jane Street, Goldman, CERN. Led by Frank Hutter, advised by Bernhard Schölkopf and Yann LeCun. Comp competitive with top AI labs. All roles: https://priorlabs.ai/careers#open-positions

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver. Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work. We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital. In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B. We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.

ProxyBase (https://proxybase.xyz) | Rust Backend Engineers & Full-Stack Developers | Remote (Global) | Full-Time | $100k-$160k + Equity Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping. Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently: 100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated. Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard. Our Tech Stack: Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing) Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app) What we're looking for: Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines. Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries.

We sit in front of these engines and fix it. We want real depth in speech and phonetics: grapheme-to-phoneme, IPA, ASR/TTS internals, and the ability to build and evaluate models around them (the recognition and G2P side especially). You should be comfortable shipping with agentic dev tools like Claude Code and Cursor. This is a 0 to 1 founding voice AI engineering role with a genuine path to Chief AI Officer for the right person. Part-time to start (flexible hours, ~2hr/day overlap with US Pacific), with a paid take-home and a paid trial month before anything longer term. Potential conversion to full-time role.

Orbit | Product Engineer | Full-time | REMOTE (EU) | German a plus Orbit is an AI-first logistics operating system — order intake, route planning, carrier management, driver app, tracking, documents — replacing the Excel-and-phone stack that most of transport logistics still runs on. We're bootstrapped, profitable, and growing in a market full of VC-funded competitors. Our customers stay because the product works. The role: we call it Product Engineer because you own a piece of the product from idea to production — deciding the solution, building it, shipping it, iterating on feedback. Not ticket-driven work. Small, strong team. How we build: spec-driven agentic development, not vibe coding. You orchestrate agents against structured specs and persistent project context, verify output, and help build the harness itself (skills, context layers, workflows, evals). We think the engineering bottleneck has moved from typing speed to judgment — knowing what good software looks like and directing agents to produce it. If that matches how you already work, you'll feel at home. Stack: TypeScript everywhere, zod, tRPC, Node.js, AWS (Lambda, DynamoDB/ElectroDB, SST), React/Remix, React Native/Expo. AI layer via Bedrock. You don't need to know every line of it. Culture: all-remote (EU), async-first, low-meeting. Writing is the most important skill here. Profit sharing via our "Own Orbit" program, quarterly meetups in Hamburg, team offsites ("SpaceWalks") wherever two or more Orbiters want to meet — Orbit covers the stay. Good English required; German is a plus (customers and product are German-speaking). No cover letter. Show us something you built — a side project, an agent workflow, a repo, an MCP server — and tell us how you work with agents. Apply: https://join.com/companies/orbit/16414503

RedLine Solutions is hiring a fully remote mid-level C#/.NET developer. We are looking at an early September start date. I'm posting this way ahead of time to try something weird: If you are an interested developer, please do NOT contact me directly. Instead, find someone who will vouch for you and have them send me your resume`. I do NOT need them to write a full-on recommendation--a simple, "Ross was a great developer and fun colleague. You should check him out" will be fine. 1. Please make sure your contact information is on your resume`! 2. We need a developer located within three hours of Pacific timezone. No, I'm not on some kind of power trip (yet). I just got my fill of automated application spam a long time ago; the tales I could tell. This is my modestly creative attempt to circumvent the AI's. Might be good practice for SkyNet, eh? We are not looking for a know-it-all. Instead, we desire a "wants to learn it all". We're a small company, but our System Architect / Dev Lead is seriously a unicorn. If he mentors you for a year or two, your career is golden with or without AI. Back in the day, I secretly believed I was one of the best around. Then I worked with Stephen. I've learned a ton from him, and I'm his boss. We're a small, agile, creative and laid-back team who work hard but value work-life balance. I take great pains to make it so. If you're smart, work hard, and love writing software, ask a friend or former boss to vouch for you and have them send your resume`.

Obsidian Security | Staff Software Engineer | Philadelphia or Palo Alto | Full-time | $176k-$196k + equity + 401k | https://job-boards.greenhouse.io/obsidiansecurity/jobs/51527... We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector. Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it. Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling. Apply via the link above, or see all our open roles at https://www.obsidiansecurity.com/careers

Syntropic (thesyntropic.com) | Founding CTO / GPU Systems Engineer | Remote (US) | Equity-heavy We compress LLM KV cache. Measured: 8× at 3-bit with 0.43% quality delta (GPU-validated); 22× live end-to-end on a 5-tenant workload, GPU-verified this week (quantization × prefix dedup, decomposition always stated); 16.89× tenant density on a single V100-32GB. Validated across Mistral/Qwen/Llama with zero re-tuning. 90+ patents pending; design-partner pipeline; seed round in motion. The gap: our throughput path is a reference implementation.

Trinsic | Senior Product Engineer | REMOTE (Europe) | Full-time We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards. Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step.

We work on identity. Sloppiness here is not an option. Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks. Comp & apply - Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time. - Apply: https://www.trinsic.id/careers/senior-product-engineer?utm_s...

Quantum Rise | Chicago or NYC (preferred), Remote for the right candidate | Full-time | No visa sponsorship | https://www.quantumrise.com/ Quantum Rise is an AI-forward consulting startup serving the mid-market in the US. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions. Agentic AI Solutions Manager: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world. AI Solutions Engineer: You're someone who has experience across the entire spectrum of applied automation, machine learning and agentic engineering. We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick the right solution not the one they saw in the news. Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries. To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

Ditto | Engineering & Product | Remote (US: Atlanta, Austin, SF, Seattle) + APAC | Full-time https://jobs.ashbyhq.com/ditto https://docs.ditto.live/home/about-ditto I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us. Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months. Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status.

Kinxshn | Forward Deployed Engineer - backend - python | REMOTE (Europe) | Full time | Funded We build AI agents that run real operations. Humans talk to our agents to run commercial real estate: leases, contractors, invoicing, accounting. We're live in production across several European jurisdictions, with real customers and real money. We need a Forward Deployed Engineer to own a client-facing use case end to end: a strong backend engineer who is also the face of the team to the customer. The job: - Talk to clients directly and often. Pull requirements out of messy conversations, explain tradeoffs, own the relationship - Turn jurisdiction-specific lease rules, tax and accounting mappings, client-specific workflows into tools our agents call - Ship to production in your first month, then keep it alive What we need, in this order: 1. Self-driven, real ownership. You'll have a lot of freedom and support, but the use case is yours end to end - nobody will be feeding you tickets. 2. Excellent English and real customer-facing experience. You'll be on client calls every week. 3. Serious backend experience. You've shipped and operated production systems, and can work as the only engineer in the room. We use AI tools heavily, but we don't vibe code: your engineering judgment and review are what make the code shippable, and you own what you merge. 4. LLM agents in production, or you ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call. Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain/LangGraph, operator or consulting background. We're a small senior team across Europe and South America. For this role we need you in Europe. Competitive comp - we have no salary bands, for the right person we'll stretch. Apply: mercedes@kinxshn.com, subject "HN - Forward Deployed Engineer", salary expectation and CV attached - skip the skills inventory: tell us about something hard you shipped and a customer you made happy.

fractile.ai - AI hardware, backed by Founders Fund - London (UK) - Onsite ABOUT FRACTILE Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the amount of time they take to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts. We’ve recently raised $220M from Founders Fund and Accel and the most important work lies ahead. Come and join the mission! THE ROLE As a Software Engineer you will be a core part of our technical team working alongside the hardware, software and research teams to solve cutting-edge problems in AI hardware, ranging from verification to simulation, alongside the best of the best (DeepMind, Apple, Meta…). ABOUT YOU 1) You have exceptional ability. We look for pivotal IC contributions that solved the hardest problems in big tech companies or hedge funds; competitive hackathons, International Olympiad medals, or rank highly in other competitions like advent of code 2. You are a top engineer. We are not looking for specific languages or technologies - you will be a master of several, you excel at algorithmic skills and solving problems logically in any programming language. And you are very comfortable learning new skills on the fly. You like to work in Python and C++ 3. It’s likely you have several years of professional experience, but we will make exceptions for the right candidate 4. You want to work with the best. And you are excited to work in chips, solving the hardest problems at the frontier of AI WHAT WE OFFER 1. Competitive compensation and meaningful equity 2. A very cool office with London's best views 3. Private medical insurance and pension benefits If this sounds like you, ping carmen@fractile.ai

Axle Health (health tech x logistics) | Backend, Interoperability, and DevOps roles | ONSITE: Santa Monica (5 days) | https://www.axlehealth.com/careers Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right. We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started. The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.

*Y Combinator | Product Engineers | San Francisco (Onsite) | Full-time | https://www.ycombinator.com/software YC is hiring Product Engineers to build the future of YC -- and increasingly, software for startups everywhere. We're a team of ~20 engineers building everything from Work at a Startup and Demo Day to investor software, founder tools, AI systems, and new open source projects. We don't have PMs. Engineers talk to users, decide what to build, and ship quickly. Some of what we've been building: * New products: GStack rethinks the software stack for an AI-native world. GBrain explores persistent memory and knowledge systems for AI. Paxel and other AI-powered products help founders—and increasingly everyone else -- build software and companies faster. * Products at scale: We build and operate Work at a Startup (2M+ candidates, 1000s of early startups), Demo Day, our investor marketplace, SAFE signing, founder CRM, and the software that powers YC itself. * Data: YC has over 20 years of proprietary startup data. We're applying it to how we think about the future of YC's batch, fundraising tools, hiring, recommendations, and entirely new ways to help people start and grow successful companies. AI has fundamentally changed how we build software, and we're looking for engineers who are already experimenting with coding agents, MCP, LLMs, context engineering, evals, developer tooling, and whatever comes next. Our stack includes Rails, React, Postgres, Python, TypeScript, LLM APIs, and plenty of experimental infrastructure, but we're much more interested in great builders than expertise in any particular framework. We're in person in San Francisco (Dogpatch). You'll work closely with founders and alongside people like Garry, Jared and Diana, helping define how YC—and startups more broadly—build software in the AI era. We offer competitive compensation, carry in the YC fund, and a small, high-autonomy engineering team. Learn more about the team and role at https://www.ycombinator.com/software. If this sounds exciting, I'd love to chat -- email me directly at ryan@ycombinator.com.

This Dot Labs Open roles: • Engineering Leads • Senior Engineers What we’re looking for: • Strong frontend engineering experience • 7+ years building production systems • Engineers already using AI in real workflows • Systems thinking and technical ownership • Comfortable working across teams and ambiguity Fully remote with US time zone overlap required.

airCFO (https://aircfo.com) | Founding Engineer | Remote, UTC -8 - UTC +2 | Full-time, part-time possible for the right candidate airCFO is an AI-powered accounting & finance services partner to 300+ startups (current/former clients include Anthropic, Replit, Harmonic), and we are building a platform to supercharge our service's capabilities. We're hiring a founding engineer to build the systems behind it: a retrieval/RAG context layer over all our tools, and the internal apps (TypeScript, Node, Python/FastAPI, React, Postgres, Claude + MCP) our teams use daily. We want someone senior who drives coding agents hard but refuses to lose the plot — clean architecture and a real mental model of the whole system. Production RAG/agents a plus, not a requirement. You'd report to a hands-on fractional CTO; small team, high autonomy. Email me at yair [dot] aviner {at} aircfo.com with "HN - Founding Engineer" in the subject.

Ashby | YC 19 | REMOTE | Hiring Engineering Manager (Americas) | $200k–$275k Ashby is the all-in-one recruiting platform powering hiring at the world's most innovative companies. If you cmd+f "Ashby" you'll see that we're powering many of the job postings in this thread! We’re looking to scale our engineering leadership team with technical leaders who want to raise the impact of a high-performing organization. * Not Your Traditional "Jira-Manager": Our EMs are not classic delivery coordinators who shuffle meetings or build heavy processes. Instead, you will own people, hiring bar, technical judgment, and the health of our engineering systems. * High-Autonomy Team: Because 80%+ of our engineering team is Senior–Staff+ level, our engineers already possess a high degree of ownership. Your focus is less on day-to-day task coordination and more on coaching independent owners, managing ambiguity, and raising team impact. * Technically Credible Leaders: You will stay close enough to the work to challenge assumptions, review proposals, spot maintainability issues, and jump into the code to debug alongside engineers when needed. * Organizational Advocates: Beyond your immediate team, you will act as an advocate owning the health and metrics of org-wide areas—ranging from CI/CD health and developer productivity to customer success collaboration and on-call sustainability. * 100% Remote Async Culture: We maintain an even distribution of engineers across North America and Europe, optimizing for minimal process and maximum focus. * Here's how we're thinking about AI at Ashby:https://www.ashbyhq.com/blog/engineering/ai-ashby-engineerin... * Full transparency on engineering levels + comp:https://www.ashbyhq.com/blog/engineering/leveling-and-compen... Stack: TypeScript (frontend & backend), React, GraphQL API, Node.js, Postgres, Redis. (While you won't always be shipping code, you are expected to hold a deep technical understanding of the system).

Colonist | Senior Product Engineer, QA Engineer | Full-time | Remote & async Colonist (colonist.io) is a multiplayer board game platform. ~20 people, millions of monthly players, no middle management between you and the product. You'll own features end-to-end and ship to a live player base within days. Right now we're evolving the core experience and building toward a multi-game platform. The mission is to become the internet's biggest board game platform. This role is a good fit if you: want to see your work matter at real scale without a large team around you, are comfortable with ambiguity and don't need someone to define your tasks, and use AI tools as a genuine multiplier in your workflow. This isn't a good fit if you: prefer a larger team with specialists for every layer, or are looking for a role with clearly scoped tickets.

Portless | AI Engineer | Remote (North America) | $180k-$230k | Full-time We're a company doing real operational work in e-commerce/3PL logistics. AI usage internally is still basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows in production yet. That's what this role is for. You'd be the first dedicated AI engineer here. Two things at once: ship agentic workflows that replace real manual work, and build the underlying platform (APIs, MCP tools, docs) so other teams can build their own instead of asking you for everything forever. First project: an agent that reads an inbound invoice question, pulls the correct (often complex) invoice, and drafts a context-aware reply a teammate can review and send. Currently ~1 hour of manual work, target is ~30 seconds. What we need: 3+ years SWE, 1-2+ of which building production AI systems (not prototypes) 10+ agentic/LLM workflows shipped end-to-end — not toy demos Evidence you've built infra/tools for other people to use, not just yourself Strong Python and/or TypeScript Some background in e-commerce, 3PL, logistics, or comparable B2B ops Nice to have: RAG, vector DBs, multi-step orchestration, eval frameworks, heavy Cursor/Claude Code/Copilot usage. Fully remote, direct access to leadership, real scope to define how AI gets built here rather than inheriting someone else's stack.

This is a founding seat to build that: shipping high-impact agentic workflows yourself, plus reusable building blocks (APIs, MCP tools, docs) so any team can build their own. Example first project: an agent for inbound invoice questions — reads the question, pulls the right invoice, drafts a context-aware reply — turning an hour of manual work into ~30 seconds.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users. The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies. We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID. We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role. Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day. We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year. See our roles here: https://jobs.ashbyhq.com/spruceid

Sports Trading Exchange | Founding Engineer / CTO | Remote USA | $140–200k + meaningful equity + founder seat available We're building a peer-to-peer exchange where fans buy and sell positions in individual athletes, like a stock. Real money, central limit order book, mechanical settlement against a published rules-based rating computed from official on-field stats. There is no house. Fans trade against each other like a prediction market. We are far along on everything except the build. Rating methodology is designed, legal structure is scoped with counsel, payments and data vendors are selected, and we ran a beta this past NFL season that drew ~1,000 organic users and 21,000 trades in four weeks. The founding team was part of Founders Inc, and we are about to open our seed round. We are hiring the engineer who owns the entire technical build, with no inherited architecture and nobody between them and the problem: Matching engine and order book Rating and settlement engine, deterministic, computed from official stats Ledger, custody, and the real-time data pipeline Every architecture decision, including one we have deliberately left open: on-chain vs off-chain custody and settlement at v1 Looking for someone who has built correctness-critical, concurrent systems. Trading, exchanges, payments, or comparable. Language is open. We care about systems depth, not a specific stack. Two non-technical founders, so you would own the technical domain completely and be the technical voice with investors and eventually regulators. Email me leon@fansharesapp.com if interested, thanks

StatusPal | Founding GTM Lead | REMOTE (Europe / EU-overlapping timezone) | Full-time | €55–75k base + uncapped commission (~€100–140k+ OTE) + 1–2.5% founding equity StatusPal helps engineering and IT teams detect, fix, and communicate incidents — monitoring, incident response, and status pages in one platform. We're small, profitable, and bootstrapped (no VC, no runway clock), with real revenue and customers. What we haven't built yet is a growth engine — that's this role. We're hiring our first commercial hire to own go-to-market end to end: both marketing/demand (content, SEO, partnerships, paid) and sales (outbound, demos, closing). You'd wake up thinking about how we sell more, lean on AI to punch above your weight, and bring in freelancers or reps when the numbers justify it — running the whole function so it compounds without the founder in the day-to-day. Strong fit if you've done a hands-on 0→few-million at an early-stage B2B SaaS and want real ownership and upside over a big-company base. Not a fit if you want a finished playbook, warm leads handed to you, or to be purely a marketer or purely a closer — this role owns the whole path. I'm the founder and will reply to everyone.

Mentimeter | Engineering Director | Stockholm, Sweden | ONSITE (hybrid, 3 days/week in office) | Full-time Mentimeter turns presentations into conversations – live polls, quizzes and Q&A that get every voice in the room heard. Product-led, 300M+ people have used it, and we are going multi-product. I am the CTO. I am hiring an Engineering Director – one of two, reporting to me. The ask is big. We are making the agentic development lifecycle the one way we build – SDLC is out, ADLC is in. I want a partner to work out with me what an engineering org is when AI writes most of the code. Nobody has that playbook, yet. We get to co-author it, and help set patterns others copy. The shape: 5–7 teams, 30–40 engineers, led through Engineering Managers and Staff Engineers. You own technical direction, architecture and the engineering-quality bar, and co-own outcomes with Product and Design. You were an excellent engineer before you were a leader. Practical: Stockholm HQ, 3 days/week in office. Daily work is in English (50+ nationalities). No visa relocation sponsorship for this role. Apply here: https://job-boards.eu.greenhouse.io/mentimeter/jobs/49089461... – please mention that you came from HN.

Prolific | Senior Software Engineer | Hybrid ONSIDE 1-2 days/wk Bay Area | $200k-$250k Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models. We’re looking for impact-focused Software Generalists to join our specialized team focused on serving frontier model creators and enterprise AI application developers. As a full-stack engineer, you will work across Prolific’s domains to solve customer and product problems. This is an exciting opportunity to work directly with frontier AI companies, making critical technical decisions that balance scrappy startup execution with scalable, reliable engineering, as Prolific revolutionizes research for the AI community. You'll will have regular in person collaboration with customers and our US team, as well as collaborate closely with our UK-based tech teams. Unfortunately we don't sponsor US visas at this time. Apply: https://job-boards.eu.greenhouse.io/prolific/jobs/4767348101

Opendate | Senior Full-Stack Software Engineer | Remote (US) | Full-time Opendate builds the ticketing platform powering independent music venues across North America. We're looking for a senior engineer who is pushing the boundaries of AI-assisted software development. Everyone says they use AI. We're looking for someone who has gone much further—someone who is constantly experimenting with new workflows, building agents, automating entire pieces of development, and rethinking what one engineer can accomplish. Our engineering team believes AI is fundamentally changing what great engineering looks like. We want people who are helping define that future—not waiting for someone else to. Our stack includes Ruby on Rails, React, PostgreSQL, AWS, Sidekiq, and Stripe, but we're far more interested in how you build than the specific technologies you've used. If you're excited by questions like: How can AI own an entire feature from design to deployment? What engineering work still requires humans, and what should be automated? How do we move dramatically faster while maintaining an exceptionally high bar for quality? What does an engineering organization look like when every engineer has AI teammates? ...you'll probably enjoy working with us. If this resonates, we'd love to hear from you. https://www.opendate.io/careers/senior-full-stack-software-e...

Fusionbox | Python + TypeScript Engineers | United States | Full-time | REMOTE (US-only) We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on. We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions. A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you. We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Acme | Remote / In-person (flexible) | Full-time | Founding Full-Stack Engineer Acme is building a product. We are an early-stage company at the ground floor — no code yet, no customers yet, just a clear vision and a bias for action. We are looking for a founding engineer who wants to build something from nothing: architect the system, write the first line of code, ship the first version, and grow alongside the company. What You'll Do: - Build the product end-to-end — from database schema and API design to frontend UI and deployment infrastructure - Make architectural decisions — choose the tech stack, set up CI/CD, monitoring, and dev environments - Ship iteratively — get working software in front of users fast, then improve based on real feedback - Set engineering standards — establish coding conventions, code review practices, and a culture of quality - Influence product direction — work directly with the CEO on what to build, what to cut, and how to prioritize - Own the infrastructure — provision cloud resources, manage deployments, and keep the app running in production Who You Are: - 3–8 years of software engineering experience, preferably in early-stage startups or with significant side-project shipping - Full-stack capable — comfortable across frontend, backend, databases, and infrastructure - Ship-focused — 80% today beats 100% next month. Pragmatic tradeoffs between speed and quality - Independent — thrive without a playbook. Figure things out, make decisions, communicate clearly - High ownership, low ego — care about the mission and the team, not about who gets credit - Product-sensible — good judgment about what users need and what can wait Compensation: Competitive salary + meaningful equity (2–5% range) How to Apply: Send a note to the CEO with what excites you about early-stage building, a link to something you have built (GitHub, portfolio, side project), and why Acme specifically. No formal resume required.

Unexus | Lead DevOps Engineer | Baarn, Netherlands | HYBRID (1 day/week onsite) | Full-time | €85k-95k We build UCS, an omni-channel contact-center platform used by Dutch housing corporations and municipalities. Profitable, ~40 people, 15+ years in market. Our platform runs reliably but the way we operate it is behind 2026 standards. You'd own that gap: moving from PowerShell-script deploys toward infra-as-code, real observability and clean deployment automation. First hire in a new platform team, growing to 3-4 people. Reality check: it's a .NET-on-Windows/Azure shop (IIS, Windows services, SQL Server), so pure Linux/K8s/Go isn't the fit. We deliberately don't run Kubernetes (tens of tenants, office-hours workloads); Ansible + Compose-per-VM is the likely direction. We prefer simple and boring. Light, fair on-call. Basic Dutch a plus, not required. No recruiters please. Details and apply: https://careers.unexus.nl/lead-devops-engineer

Credo Health | Full Stack Engineer | NYC (HYBRID — 1 day/week onsite, otherwise remote) | $125k–$175k + equity | Full-time I'm Ketan, Head of Engineering at Credo. We're a seed-stage, HIPAA-compliant health-tech company fixing one of healthcare's dumbest problems: getting the right patient data to the people who need it. Billions of pages of medical records still move by fax every year — causing care delays, admin overload, and dangerous gaps in what providers know. Our AI platform gets clinicians the patient answers they need fast. We have paying customers using it daily. This is an early engineering hire on our Platform team (5–7 people), reporting to me. You'll work the full stack, shape our architecture, and ship to real users every week. High ownership, lots of surface area, frequent collaboration with our ML team. Stack: Python/Django, Postgres, Vue, Temporal (for our patient-ingestion pipeline and long-running workflows), Google Cloud, and a mix of AI models (mostly Gemini + OpenAI). No prior Temporal experience needed, just enthusiasm for it. How we work: strong code-review and pairing culture, serious about testing, async-first with a single daily sync, and we've fully integrated plan/spec-based AI tooling into our workflow (Claude, Cursor, CodeRabbit, Copilot — your choice). Looking for 3–5+ yrs full-stack experience, solid Python + a backend framework, comfort with relational DBs, a modern JS framework, real testing chops, and someone who thrives with ambiguity and owns problems end to end. Healthcare/FHIR/HL7 and AI-feature experience are nice-to-haves, not requirements. Must be in/near NYC for the weekly in-person day. Apply here: https://app.dover.com/apply/Credo%20Health/0cc80a85-2953-40c... Happy to answer questions in the thread!

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility) Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured. We're hiring for two roles right now: - Product Engineer / Senior Software Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market? - Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast. Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m). Please email us at jobs@kinelo.com. If you want to stand out: - For the product engineer role, tell us how you think the job of a software engineer is changing. - For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.

Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git. We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs. Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents. Junior Software Engineer - Remote (Global), Full-Time We’re looking for remote junior engineers with 0–3 years of professional software experience and 5+ years of curiosity exploring computers, programming, and technical hobby projects.

Ideally, you’ve already graduated. But if you still have one or more years left of school, please feel free to apply anyway. If you’re the right fit for the team, we’ll figure out a way to accommodate your schedule.

About Bloomy Bloomy is an AI tutor and curriculum for K-12 students. Our student users are learning approximately 2x faster in early pilots, and students and teachers alike love our product. How it works: We diagnose students’ skill gaps, map out a personalized learning path for them, and then have an AI tutor teach them. The AI learns about how they learn, so it can increase the efficiency of its teaching and, consequently, their learning. How you can help: You will be joining as the founding engineer. Right now, engineering is one founder (me) orchestrating fleets of coding agents that produce a large share of our code and curriculum against specs, verification harnesses, and QA gates. I’m a solo founder with domain expertise as a former teacher and sales leader, but I’m not an engineer by training, and I need someone with true technical expertise to actualize the vision of improving education for millions of students. Why we’re different: Bloomy is AI-native. I built the entire product from February to April of this year, got it into the hands of 500 students across 6 schools from April to June, started YC in June, and have roughly doubled ARR every 2 weeks since then. Thousands of students will soon use our product this fall. Bloomy is also the first EdTech company to go through YC for the past 5 batches, so it represents an opportunity to be on the ground floor of one of relatively few startups trying to transform education with AI. Your first 90 days First week Ship a feature or a fix to production and watch real students in real classrooms hit it the next school day. Our loop from “merged” to “a 6th grader used it” is as short as it gets. First month Get acquainted with the React/TypeScript app, the Supabase backend, the content pipeline, and the agent fleets that feed it. Take ownership of your first fleet — write the spec, build the harness, set the QA gate — and start shipping through it. Three months later Design the roadmap with me: ~50% shipping product across the stack, ~25% building and running agent infrastructure, ~25% talking to teachers, students, and districts — and turning what you hear into the roadmap. Things we badly want to build - The data flywheel. Almost nobody in education closes the loop between that telemetry and the instruction itself. We can — for every answer, retry, AI-tutor conversation, and any other interaction — in days, not textbook-revision cycles. Design that loop. - Agent orchestration as a first-class engineering problem. Better harnesses, better evals, better verification — so that a dozen concurrent agents produce work you'd trust in front of a classroom. - Whatever schools need next. Today it's tools for students and teachers. The surface area in a school district is enormous, and you'll help decide where we go. We're looking for someone who - Has 5+ years shipping products that real end users touch daily, and has opinions about what makes them good - Is high-agency: can take ambiguous feedback and turn it into shipped product without waiting for a spec - Is expert-level with AI coding tools and uses them to move dramatically faster — without outsourcing judgment to them - Gets excited, not exhausted, by the idea of managing a dozen concurrent agents - Wants tight feedback loops with real users (some of whom are eleven) - Has high schlep tolerance — roster CSV imports, school-device performance quirks, and school-specific customization are part of the job and part of why we win - Cares about measurable learning outcomes, not just engagement metrics Preferred experience - TypeScript, React, Postgres (we're React 18, Vite, Tailwind, shadcn/ui, Supabase, TanStack Query, on Vercel) - LLMs in production: agents, evals, tool use, context management - Building codebases and pipelines designed to be worked on by agents - Event telemetry, analytics, or experimentation systems - Edtech background genuinely not required The backstory I started my career as a 7th grade English teacher, where I saw how hard teaching 30 different kids at 30 different levels of understanding really is. After building the driver acquisition engine at Lyft, pursuing various entrepreneurial ventures while getting my MBA at Stanford, and building AI agents and workflows at McKinsey from the start of the boom, I now believe education is where AI can have the largest positive impact for society. Compensation - $175K - $200K - 1.5 - 2.0% equity Founding-engineer package — meaningful ownership from day one. Sound like you? Email alex@bloomylearning.com. Include something you've built that real people used.

You’ll build features that will go directly into our customers hands, the day you ship them. With great power comes great responsibility.

Apply to role › Sri Raghu Malireddi Founder Sri Raghu Malireddi Founder About the role We built Moss because Voice AI breaks when retrieval is slow. Most retrieval infrastructure was not built for real-time reasoning. It adds latency, breaks context mid-conversation, and becomes the bottleneck just as an AI product needs to feel instant. Moss is the real-time semantic search layer for conversational AI. We deliver sub-10ms retrieval directly in the browser, at the edge, on-device, or in the cloud, without making teams stitch together a slow retrieval stack. We are backed by YC and run in production for teams building serious AI products. Moss is deployed across 100+ countries, serves 10M+ of real-time voice minutes, supports enterprises serving 3000+ of their own end customers, and has 390K+ package installs. The SDKs are how every one of those developers meets Moss. They are the first thing a team touches, the surface that has to feel instant on every platform, and the layer where our Rust engine becomes real code running inside someone else's product.

We are a new robotics company based in Palo Alto, California, building wearable robotic devices. Our first product is a device that reduces the physical cost of carrying heavy loads over distance, allowing people to move farther, carry more, and arrive less fatigued. The company is early but already operating in the field, with hardware on real users and a direct feedback loop in the most demanding conditions imaginable. We are backed by Y Combinator and a group of leading deep-technology investors. We recently moved to the Bay Area to grow the team and are hiring three principal engineers (we're in stealth for the time being, but hopefully not for too much longer!). $200-250K + 1-2% equity + full benefits, onsite in Palo Alto. These senior roles each own their domain with full authority, no inherited design decisions, and no one between them and the problem. What you build will go on real users within weeks. - Mechanical (Principal Engineer): own the mechanical platform, including structures, joints, actuator integration, ruggedness, and field serviceability. You have designed hardware for robots, humanoids, or other high-performance actuated systems. - Firmware (Principal Engineer): own the embedded stack, including real-time BLDC motor control, sensor integration (IMUs, encoders, current sensing), OTA, and debug tooling. You have written real-time firmware for physical robots or autonomous systems. - Software (Principal Engineer): own the software infrastructure, including device-to-cloud telemetry, test and log databases, data pipelines, and user applications. You have built software for hardware fleets and the people who use them. Please send a note to chrome.braindance@gmail.com that shows what you've built. A resume works, but a quick description of a real project is better. Photos, videos, and links are welcome. We look forward to meeting you!

Dexter is the AI-native spend intelligence platform for complex enterprises. Big enterprises spend hundreds of millions, sometimes billions, every year buying things from suppliers, but most of them have no clear picture of what they're actually paying for. We use AI to read their invoices and contracts and turn that messy data into clear insights, so they can spot savings and make smarter decisions. Procurement is a fascinating function, responsible for huge amounts of spend, managing strategic supplier relationships and negotiations, yet is overlooked when it comes to technology. We’re here to bring them into the AI era. We went through YC in 2024, and have been growing since then. Now we're looking for a Founding Engineer to scale our engineering team, with a strong focus on using AI and automation to move faster than teams ten times our size. ### Role description As a founding engineer, you’ll work on building the Dexter product from the ground up, collaborating closely with the founders and our customers. It’s not just about shipping code, but rather owning projects end-to-end, making product and technical decisions, talking to customers, and making Dexter a successful business. Some of the problems we currently solve for our customers include structured data extraction from documents (invoices, contracts, etc), autonomous agents matching documents and entities together, and AI assistants assisting them in their tasks. It’s the full range of applied AI in the enterprise. ### Key Facts - Location: Berlin, on-site at least 4 days a week - Employment type: Full time - Compensation: €60k–€100k + meaningful founding equity - Tech stack: AWS, Ruby on Rails - Working language: English (German is a plus for our customers) - Work authorization: you already have the right to work in the EU ### Who we are looking for - Velocity: Everything you do, you do with speed - High Agency: “I’ll figure it out” mentality - High Ownership: nobody has to tell you what to do, you just do things - You’re excited to work with AI - You have either: - A Masters in Computer Science, Mathematics, Physics - 4+ years of professional software engineering experience ### What would make you not a good fit - You prefer to work remotely - You want well-defined problems to solve - You want to work 9–5 - You’re in it for the tech, not customer problems ### What we offer - A high-impact role in a fast-growing YC AI startup - Work on cutting-edge AI functionality like autonomous agent systems - Direct, daily collaboration with experienced founders - A steep learning curve with real responsibility from day one - Exposure to sales, strategy, product, and company-building - Competitive compensation that recognizes your value ### About us We’re a team of builders and operators who love solving tough problems. Our founders, Vincent (ex-SoundCloud), Caterina (ex-Uber), and Bella (ex-HubSpot), met while scaling operations at Dance and saw firsthand how critical supply chain and procurement operations are to real-world products. So we built Dexter to help. We’re backed by Y Combinator and growing fast. ### How To Apply Send us an email at jobs@getdexter.co with a short text explaining why you want to join Dexter and your LinkedIn and GitHub profiles.
