Job description

Founding Senior Full Stack Engineer #2 | YC Healthcare AI

London | £80K-100K + 2% equity | Visa sponsorship | 4-5 days onsite

I'm exclusively hiring Engineer #2 for one of Europe's fastest-growing pre-seed AI startups.

They're building an AI platform for pharma commercial teams, sitting on a healthcare dataset covering 9.2M+ clinicians, 3bn prescribing claims and $11bn in tracked payments.

They've raised $2M at a $20M valuation, are on track for £1M+ ARR in year one and are close to signing one of the world's largest pharma companies.

The Senior Full Stack Engineer role

You’ll join as Engineer #2 and work across the entire product, from the data underneath it through to the features enterprise customers use.

Think data pipelines, mapping and normalisation alongside Python services, AI-powered search, analytics, enterprise workflows and frontend product development.

This needs someone autonomous who can understand the business problem, decide what should be built and ship it without needing a detailed brief.

What they’re looking for

• You were a core engineer on a data/AI-heavy B2B product
• You helped take it from building through to adoption by at least one large enterprise customer
• You’ve worked hands‑on with data pipelines, mapping or normalisation
• You’re genuinely full stack and comfortable across backend and frontend
• You’ve built for a regulated/compliance-conscious industry and understand things like SOC2
• You’re comfortable owning ambiguous product problems in a tiny engineering team

Healthcare is ideal. Fintech, legaltech and other regulated B2B environments translate well.

Stack

Python, FastAPI, TypeScript, Next.js, Azure, MongoDB, Elasticsearch, Databricks and Neo4j.

Exact stack match matters less than the problems you’ve solved.

For this Senior Full Stack Engineer role they’re paying £80K-100K + 2% equity. VISA sponsorship available. 4-5 days onsite in Hammersmith.

They’re running a 3-step interview process and will be making this hire over the next few weeks so get in touch ASAP.
