Data Engineer

London - 4-5 Days per Week in Office

£70,000-£90,000 + Equity + Benefits

We're working with a rapidly growing, YC-backed healthcare AI startup building a market-leading data platform used by pharmaceutical, biotech and healthcare organisations.

The Opportunity

This is not a role where you'll maintain legacy pipelines or work on a small corner of an established platform. The team is specifically looking for engineers who have experience taking products, platforms or major features from 0-1 .

You should be able to demonstrate that you've:

Built something from scratch rather than simply maintained existing systems

Worked through ambiguity with limited requirements

Designed architecture and made key technical decisions

Owned delivery from idea through to production

Worked closely with product teams, users or founders to shape solutions

Shipped products that generated real business value

The successful candidate will help build and scale the core data infrastructure powering the company's platform, taking ownership of projects from raw data acquisition all the way through to production-ready products.

What You'll Be Doing

Building scalable ETL/ELT pipelines using Python and SQL

Designing and developing data ingestion frameworks

Working with large, complex and often messy datasets

Leveraging AI and LLM technologies for extraction, classification and enrichment

Building data products that directly support customers

Designing schemas, entity resolution and data quality processes

Collaborating closely with engineering, product and leadership teams

Taking projects from concept through to production deployment

What We're Looking For

Essential

Strong Python and SQL skills

Experience building production-grade data pipelines

Proven ownership of end-to-end engineering projects

Experience building products, platforms or major capabilities from 0-1

Ability to operate independently in a fast-moving environment

Strong problem-solving skills and technical foundations
