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.

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.
