Lumen Labs | Simulation/RL Integration Engineer | REMOTE (US/Canada), then ONSITE SF from fall 2026 | $130k–200k + early equity | Visa OK
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.

BW Events Tech | Senior Software Engineer | REMOTE | CONTRACT (~40 hrs/wk, hourly, rate DOE + location) | Python/Django/React, AWS + GCP
We build ShowUp, the software that runs live events end to end: check-in, badging, session scanning, lead capture, exhibitor portals. It runs in real time, on-site, where there's no second chance to get it right. We work with teams of every size, including three of the Fortune 5, across hundreds of events a year worldwide.
We're hiring one senior engineer to own core platform development - improvements, integrations, reliability — and ship it end to end. You'll work with our eng lead, who sets architecture and reviews the work, while you run with a lot of autonomy. We want someone who can take an ambiguous problem, scope it, and ship it without needing it broken down first. Builder role: no reports, real ownership.
We're an AI-forward team and lean on AI tooling heavily to punch above our size; we expect you to use it to amplify your judgment, not replace it.
Stack: Python, Django, React, on AWS and GCP. More detail: https://docs.google.com/document/d/18F2bypRBJxQDTsTNdazpz2SB...
Looking for: 8+ years, senior experience owning complex domains, fast ramp in unfamiliar codebases, strong judgment on ambiguous work, fluent everyday use of AI tools, clear communication. Event-tech or integration-heavy background is a plus. Rate: 60-100/hr USD DoE.
Individuals only — no agencies, staffing firms, or third-party recruiters.

Portless | AI Engineer (Founding seat) | Remote (North America) | $180k-$230k
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.

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

Comograph — replacing resumes with verified proof of work. Engineers complete real challenges, get a capability score, and are hired on evidence, not credentials. We're two pre-seed founders looking for a founding Product Designer/PM — someone to own the entire design system and UX (engineers + employers) from scratch, and help shape the roadmap, not just execute briefs. Looking for someone who's shipped real products, thinks in systems, pushes back on bad ideas, and is comfortable with total ambiguity. Two-sided platform/marketplace experience a big plus. Honest caveat: no salary yet, pre-revenue. What's on offer is founder-level equity and real ownership. If you've looked at hiring platforms and thought "this is solvable" — email ceo@comograph.com with a portfolio and a note on what you'd fix about hiring today (that part matters more). comograph.com

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.

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.
