Head of Data Science

Head of Data Science (London, Hybrid)

We’re partnering with a high-growth, profitable UK scale-up building a category-defining product at the intersection of technology, finance, and sustainability.

They’ve already reached significant scale (hundreds of thousands of users), have strong unit economics, and are now entering the next phase of growth, where data science becomes a core competitive advantage.

You’ll start as a hands-on leader, owning and deploying production-grade machine learning models that directly impact revenue, risk, and customer experience, while simultaneously building the function around you.

What you’ll actually be doing:

• Designing and deploying ML models across areas like risk, churn, and personalisation
• Owning projects end-to-end (problem → model → production → monitoring)
• Working directly with senior stakeholders across product, engineering, and commercial
• Defining the long-term data science roadmap
• Building a high-performance team over time

What they’re looking for (non-negotiables):

• ~7+ years in data science / ML with production deployment experience
• Strong academic background (STEM / quantitative discipline preferred)
• Proven ability to translate models into commercial impact
• Comfortable operating as a hands-on IC + leader
• High ownership mindset — you take responsibility for outcomes, not just output

Why it’s interesting:

• Profitable, scaling business
• Data is already central, you’re not starting from zero
• Direct impact on core business levers
• Clear path to building and leading a team
• Hybrid (3 days/week in London)
