Founding Engineer – Stealth AI Startup | London | £100–200k

• Location: London (Onsite)
• Compensation: £100,000–£200,000 + meaningful equity
• Start date: Flexible, but ideally soon

I'm hiring for a stealth-stage AI startup founded by two individuals who have worked at some of the biggest names in the space. Backed by deep technical roots and a bold vision, they’re rethinking how enterprises interact with AI, by teaching systems directly through human decision-making.

They are a small team with less than 10 heads, and they're now looking for a founding-level engineer to join the core London team.

Tech stack:

• Frontend: React, Next.js, TypeScript
• Backend: Python, FastAPI

Happy for candidates to lean towards to backend or the frontend

Why this role stands out:

• Stealth-stage, high-impact: You’ll work on tech that’s pre-launch but already being used by early design partners.
• Truly novel approach: Building systems that learn from human behaviour rather than traditional fine-tuning.
• Deep product involvement: Ship fast, iterate constantly, and help define how AI will interface with the enterprise.

If you're a Full Stack Product Engineer who thrives in fast-paced, early-stage environments and you're excited about the future of AI automation — Apply now!!
