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.
Full JD + Apply: https://uctalent.io/referral/Huynh_Nhu_Bao_Nhan221138/DNwhgw...
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.
Must overlap ~6 hrs with US Eastern (9am-4pm ET).

Proton builds the privacy-first alternative to Big Tech: Mail, VPN, Drive, Pass, Calendar, and Lumo AI. We're profitable, have no VC control, and are majority owned by the nonprofit Proton Foundation, so no one can force a change in mission.
The Drive Foundation team builds the core SDK powering every Proton Drive client,C#, TypeScript, and Rust daily, with Swift and Kotlin bindings for mobile. It's foundational work: what you build here ships to every Drive client, and there's a crypto model revamp plus a Rust based next gen SDK on the roadmap.
Looking for someone with 5+ years of professional software experience and strong Rust expertise (ownership, concurrency), plus experience building libraries for client applications (web/mobile/desktop). Don't check every box but think you'd be a strong fit? We say apply anyway.

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.
Namecoach has spent 10 years building the largest verified pronunciation dataset of its kind: ~2M self-recorded name pronunciations, plus a large corpus of human-verified phonetic spellings.
We're now building Euphonia (https://euphonia.namecoach.ai/), a provider-neutral middleware layer that makes any TTS engine pronounce names, acronyms, and other out-of-vocabulary terms correctly. The new wave of TTS (models from OpenAI, ElevenLabs, etc) sounds great but gives you almost no phoneme-level control, so it gets lots of names and words wrong and you can't easily fix it. 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. Series A closed, bridge to B in motion.
Full JD: https://wellfound.com/l/2ChdJ2
Email hiring+hn@name-coach.com with a short note on what interests you and a link to something you've built. G2P / TTS / ASR open-source work gets read first.
Lumen (https://lumenresearch.ai) is building the cognitive layer for physical AI. Most robotics efforts today learn from thousands of hours of human teleoperation; we think that has a ceiling. White paper: http://lumenresearch.co/paper
Team of two ex-founders — you'd be #3. Pre-seed, runway well into 2027, raising a seed later this year.
We test many model architectures against many sims, and hooking them together is our biggest pain point. We use Gymnasium and Shimmy as the plumbing and upstream useful pieces as open-source contributions. You'd build per-sim adapters to a shared interface contract, bridge single-env vs. GPU-vectorized and sync vs. async paradigms, and own our eval harness.
Looking for: strong Python, Gymnasium (especially the vector API), hands-on experience with Isaac, MuJoCo, or Gazebo, and a track record of getting models running in sims where they didn't before.
Email hi@lumenresearch.co about you and your projects — link one where you got a model working in a sim it wasn't built for and you'll jump the pile.

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
ResortPass is rebuilding the web experience behind one of the largest hospitality marketplaces. We're rewriting ~75% of resortpass.com this year, focusing on Core Web Vitals, SEO, performance, and developer experience.
Roadmap this year is aggressive: international expansion (Mexico/Caribbean, then Europe), moving search off Algolia in-house, a new Hotel SaaS product, Spa as a new business line. AI features (concierge chat, AI booking assistant) are also landing on this frontend, so there's exposure there too.
You'll help lead large frontend initiatives, define architecture, mentor engineers, and work closely with Product and Backend teams.
Tech: React 19, Next.js 16 (App Router), TypeScript, Tailwind, shadcn/ui, Playwright, Datadog, Node.js, Ruby on Rails, PostgreSQL, MongoDB, AWS.
Looking for engineers with 6-10 years of experience building production web applications and deep expertise in React/Next.js.

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. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. 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.

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. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

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. First job is the fused Triton/CUDA dequant+attention kernel — turning a validated 22× memory result into production speed. Then you own the serving stack.
Process: call → NDA → paid 1–2 week trial on the real kernel → decide together. We report negative results straight; you should want to work somewhere that does.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

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.

We manage over $3B for CPG brands like OLIPOP, Tropicana, and Dr. Squatch. We 5x'ed revenue last year and are on track to 4x this year.
The role is engineering + customer implementation: working closely with customers that are household names to run their implementations to ground, as well as enable the broader set of customers.
Stack is Rails, Python, TypeScript, Postgres, and AWS.
Job Description: https://jobs.ashbyhq.com/confido/e3d42ff2-4ab4-4469-9091-d24...
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.
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.

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.

Construction/logistics/field-industry experience is a plus.
Competitive salary, health/dental/vision, high autonomy, early team impact.

NODA AI is the defense software company that built and fielded the original vendor-agnostic autonomy orchestrator. Founded in 2024 and headquartered in Austin, Texas, NODA builds the software layer that enables heterogeneous uncrewed systems to coordinate, adapt, and execute complex missions using human intent across contested multi-domain environments. NODA’s orchestration software is operationally deployed, hardware- and software-agnostic, and purpose-built for the complexity of modern autonomous warfare.
The demand for NODA's capabilities are growing rapidly. We're looking for engineers motivated by the opportunity to see their work applied in the real world. Our team's work goes from concept to field test in days, not months. With numerous positions currently open, you will gain access to solving real world challenges with unlimited capabilities, such as autonomous behaviors and path planning, agentic AI/LLM orchestration, distributed systems, interoperable UI and simulations, CJADC2, and edge deployment across mixed fleets.
U.S. Citizenship required due to ITAR regulations & the ability to obtain and maintain a Department of Defense (DoD) security clearance. Open engineering roles are all Austin-based unless otherwise noted. We welcome candidates who are local or open to relocating; relocation assistance is available and may be included in the offer package where appropriate.

3Play makes content accessible across disability and language. Our human-QA'd captioning, audio description, subtitling, and dubbing services are used by over 10,000 media, higher ed, creator, enterprise, and government customers. We’ve worked on really cool projects: recent examples including captioning the 2024 Paris Olympics and providing quality AI dubbing for high-profile YouTube creators.
I'm leading the Growth team, and we're working to build new, beautiful UI experiences on our long-loved services. Our stack is a Remix/Rails product and Astro/Sanity marketing site, both backed with modern design system foundation (what you might expect with Typescript, Tailwind, ShadCN, Tanstack, etc). I'm looking for a principal-level engineer with strong taste in front-end: someone who cares about UX and styling, takes accessibility and page weight seriously, builds strong validation / testing harnesses, and keeps a dependency tree sane instead of letting it metastasize.
The other part of this role is contributing to our agents and workflows. We've invested heavily here with the right mix of enthusiasm, guardrails, and budget. You'll have heavy influence over how it evolves: what we hand to agents vs. keep in human hands, how work gets specified and parallelized, how we keep the results beautiful, and where the security and review gates live. There’s a ton of opportunity to work with the latest AI tooling and determine best practices as the industry matures. We’re a small team happily working over 15 years with high impact, high autonomy, and low bureaucracy. Come join us! Apply at https://www.3playmedia.com/company/jobs-post/?gh_jid=7761973.... Mention HN when you apply!
Check out the jobs page on our website, or email sid@ with (HN) in your subject line.

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.

You'll own the full bug lifecycle, wire tests into CI/CD as reliable quality gates, and partner with product and engineering to build testability in from the start.
Ideal fit: 3+ years in QA testing web apps, across both manual and automated testing with modern frameworks (Playwright, Selenium) and unit/component tooling (Jest, Vitest). Comfortable testing SPAs and REST APIs, with enough JavaScript/TypeScript to write and debug test code. Bonus points for React, Vite, monorepos, micro-frontends, GitHub Actions. Above all, a user-focused mindset — catching problems before customers do.
3. Senior DevOps Engineer
We're hiring a Senior DevOps Engineer to standardize application deployments, containerization, and release processes across our org. You'll build shared CI/CD pipelines, containerize apps with Docker/Kubernetes, and create the tooling and golden paths that let teams ship reliably. Ideal fit: solid experience with CI/CD (GitHub Actions/GitLab CI/Jenkins), IaC (Terraform/Helm), and cloud providers (AWS/Azure), plus a track record of driving standardization at scale. Pragmatic, collaborative, and motivated by making other teams more productive.
