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.
