The role
This is a profitable, bootstrapped platform rewarding 80 million users globally.
They're one of Europe's fastest-growing companies, building out their first dedicated data and ML presence in London.
You’ll lead that function from day one, growing a team from a single hire to ten over the next year.
This isn't a distant management role: you'll stay a genuine technical contributor, reviewing designs and code, joining model reviews, and staying in the problems.
The work is applied and commercial: reward optimisation, real-time personalisation, offer ranking.
You're building the ground the team will stand on, not just tuning something that already runs.
- The work
- Lead the London data and ML function, defining its roadmap and technical strategy.
- Drive applied ML initiatives across reward optimisation, real-time personalisation, and offer ranking.
- Build and scale a high-ownership team from scratch, setting the technical bar and interview process.
- Contribute technically through design reviews, code reviews, and model reviews.
- Translate business priorities into technical plans, ensuring direct impact on company-level outcomes.
What You Bring
- Strong individual contributor background at senior, staff, or principal level; you want to keep building.
- End-to-end ownership of an applied-ML domain: recommendation, ranking, marketplaces, adtech, or similar.
- Clear examples of business outcomes your technical work directly drove.
- Comfort defining solutions in ambiguous environments, rather than following existing playbooks.
- Experience hiring, coaching, and setting the technical bar for a small, high-ownership team.
