Job Description
Founding Engineer – Stealth AI Startup | London | £100–140k
Location: London (Onsite) Compensation: £100,000–£140,000 + 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!!
