London (King’s Cross, mostly in-person). We’re an AI health startup building the future of preventative healthcare. We’re reimagining the entire system from first principles, with AI at the core. We’re hiring two founding engineers to bring this vision to life.
What You’ll Actually Do
- Build it all: From scratch. No tech debt, no legacy systems. You’ll own the frontend, backend, and early infrastructure.
- Design the architecture: This is your system to shape: tools, patterns, infra. You decide what “great” looks like.
- Think like a founder: We’ll lean on you to help us hire, scale, and avoid dumb decisions. You’re early, and it shows.
- Be here: We’re in-office most days. Fast, fun, chaotic. In-person energy is our unfair advantage.
Why This Might Be The One
- Founding title, real equity: We over index on equity - on principle. We want you in this with us for the long haul.
- Blank canvas: No migration plans or duct tape builds. You’re starting the engine, not fixing someone else’s car.
- Experienced founders, no ego: We’ve built and scaled companies before. We move fast, avoid drama, and make time to teach. If you’re ambitious and want to learn, you’ll grow quickly here.
- Shape the product: You’ll be side-by-side with product and design. The best engineers think in user stories.
- Shape the team: This isn’t a solo ride. You’ll play a key role in who joins next - and how we work together.
What We’re Looking For
- You’ve built and shipped full-stack apps (React, Next.js, TypeScript, etc.).
- You’re AI-curious (or experienced), and have familiarity with LLM APIs.
- You’ve integrated third-party APIs - ideally in messy, real-world domains.
- You thrive in fast-moving, ambiguous environments.
- You’re London-based and love building in the room with smart, mission-driven people.
- You want meaningful equity - and you’re ready to earn it.
Bonus points
- Experience with workflow automation tools.
- Any experience in HealthTech or regulated environments.
- Former founder / early eng hire.
