Full Stack Data Engineer – AI Research | £92K | Hybrid London (3 Days Onsite)

We’re hiring a Full Stack Data Engineer to join an elite AI research team in London. You’ll be hands-on with end-to-end pipeline development—onboarding, filtering and packaging massive datasets (text, image, video) that will power LLM agents used in cutting-edge automation and FAIR research.

This isn’t your average data role—it’s technical, research-focused, and sits right at the intersection of data engineering and software craftsmanship.

What's in it for you?

• Annual Salary up to £92,000 doe
• Length: Through December 2025, with possibility of extension
• Contract Type: Inside IR35 - PAYE - paid via Principle HR on a weekly basis
• Location: 3 days onsite, Central London

• Build Python-based data pipelines to ingest and filter high-risk datasets
• Clean, transform, validate and repackage data (text/image/video) at scale
• Work closely with data engineers and researchers to mitigate risk in datasets
• Deliver production-grade filtering solutions with minimal overhead
• Participate in daily research discussions—this is an engineering-first role with a research edge

• Solid Python engineer with proven experience in data pipelines
• Comfortable across the stack: you can build tools, services, scripts—not just run notebooks
• Skilled in dataset wrangling, filtering, and data quality control
• Exposure to machine learning or FAIR/LLM-style projects is a strong advantage
• Experience with JavaScript or PyTorch is a bonus, but not required
• Able to thrive in a fast-paced, highly collaborative research team
