Senior Software Engineer

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

The strongest signal is something you've already built:

• 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.
