Founding AI Platform Engineer — Stealth AI Start-up

Founding AI Platform Engineer — Stealth AI Start-up

£120,000-£160,000 + Equity + Benefits

London - Hybrid

I'm working with a AI start-up (backed by tier-1 European VCs) building a decision platform for high-stakes environments — helping teams navigate uncertainty and make better calls, faster.

What you'll actually be doing:

🔹 Building core product features across backend, frontend & workflow systems

🔹 Turning fast-moving prototypes into reliable, reusable product surfaces

🔹 Designing interfaces that make complex AI outputs feel clear & trustworthy

🔹 Building the platform foundations — auth, permissions, APIs, observability

🔹 Working directly with the founding team — fast decisions, no bureaucracy

What we're looking for:

✅ 5+ years building production software

✅ Strong full-stack chops (Python/FastAPI + React/TypeScript or equivalent)

✅ Solid SQL & data modelling instincts — comfortable in data-heavy B2B products

✅ Bonus: experience with agentic/LLM-powered products, tool use, evals, guardrails

✅ Bonus: API integrations (MCP, webhooks, OAuth) + cloud deployment (AWS)

Direct AI/ML experience isn't a hard requirement — strong product engineering judgment matters more.

📩 DM me or drop your CV/GitHub/portfolio — happy to share more on the product and team (confidential at this stage).
