Founding Full-Stack AI Engineer | AI Startup | London | Backed by a top-tier US VC
Hybrid in their new London Office.
Up to £130k + Equity
I'm working with a stealth-mode AI startup building AI agents for complex, real-world operations, systems that don't just answer questions but actually learn how people work and get things done.
Founded by AI and operations experts with backgrounds spanning top US universities, Tesla, and Bosch, and backed by one of Silicon Valley's leading venture funds, they're now hiring their first Founding Full-Stack Engineer in London.
The role
You won't inherit a finished product or a fixed stack. You'll help build the architecture, the product, and the engineering culture from the ground up, working across backend, frontend, infrastructure, and AI.
What you'll be doing
- Building the backend services, APIs, and data models that let AI agents operate reliably in production
- Working hands-on with LLMs, agents, tool calling, RAG, and multimodal AI
- Owning features end-to-end, from architecture through to deployment and monitoring
- Helping define technical standards and engineering practices as one of the earliest hires
What they're looking for
- 3-5+ years of software engineering experience, with strong full-stack skills and particular depth in backend engineering
- Solid experience with APIs, Postgres, system design, distributed systems, and production reliability
- Comfortable with TypeScript/Node.js and React (Python or Go backgrounds also welcome)
- Genuine curiosity about AI and a fast learning curve, prior AI experience is a bonus, not a requirement
- Comfortable owning infrastructure: cloud, CI/CD, Docker, monitoring
Nice to have: early-stage startup experience, 0 1 product experience, workflow orchestration tools (e.g. Temporal), or ambitious side projects.
This is a rare chance to join at the true starting point of an AI company with strong backing and a clear, differentiated thesis. If you're the kind of engineer who looks at a problem you've never solved before and thinks "I'll figure it out," I'd love to hear from you.
