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.

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.

AI usage today is basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows yet. 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.

Need: 3+ yrs SWE with 1-2+ yrs shipping production AI systems, 10+ real agentic/LLM workflows built end-to-end, a genuine platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript, and relevant sector background (e-commerce, 3PL, logistics, or similar B2B).

Nice to have: RAG pipelines, vector DBs, multi-step agent orchestration, eval frameworks.

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.
