Job Description

Staff Engineer - London (Hybrid) - Full-time - paying up to £150k

The Opportunity

One of the world's biggest, most mission-critical markets still runs on PDFs, spreadsheets, and guesswork. We're building the AI-native platform that fixes that - and we're hiring the engineer who'll shape what comes next.

We've found product-market fit, we're scaling fast across new markets, and our customers stick around because the product actually changes how they work. Now we need a Staff Engineer to own the architecture that gets us to the next level.

The Role

This is a hands-on, high-leverage IC role - part architect, part technical rallying point. You'll set the technical vision for our Core Markets org, align 6+ teams around it, and still write code where it counts.

You'll:

  • Own architecture and strategy across Platform, AI, Retrieval, and shared services
  • Design Back End systems and APIs that scale with a fast-growing business
  • Partner with AI/Retrieval teams to push our search and RAG capabilities forward
  • Lead cross-team initiatives from whiteboard to production
  • Raise the bar through design reviews, mentoring, and sharp technical judgment
  • Use AI-assisted engineering to move faster, not just talk about moving faster

You

  • Have built large-scale Back End systems and distributed architectures
  • Think in systems, not tickets, and can lead technical initiatives across teams without needing the authority to force it
  • Know your way around AWS, Kubernetes, APIs, and modern Back End development
  • Have touched RAG, search, or vector databases - or want to go deep on them
  • Code fluently in Python (or an equivalent modern language)
  • Communicate clearly and love levelling up the engineers around you

Bonus points: founding engineer or CTO experience, or a track record of modernizing Legacy systems.

If this sounds like your kind of problem, even if you don't check every box, we want to hear from you.
