I’m partnering with a fast-growing fintech looking for a hands-on, AI-native Head of Data Science to own its data science strategy and build the models that enable smarter, faster and safer lending decisions.

This is a high-impact opportunity for a technically strong leader who can combine strategic ownership with hands-on delivery, building and deploying machine learning models and AI agents that directly influence business performance.

• Apply LLMs and agentic AI to real-world business decisions, taking solutions beyond proof of concept and into production.
• Take end-to-end ownership of models, from development and testing through to deployment, monitoring and governance.
• Work closely with Product, Engineering, Credit, Operations and Collections to turn data science into measurable commercial outcomes.
• Lead the data science roadmap, using analytics and management information to demonstrate impact and inform senior leadership.
• Report directly to a highly regarded, award-winning data leader in the UK, with the opportunity to work alongside an established figure in the data community.
• Help shape the future of a growing fintech, with significant autonomy and influence from day one.

What We’re Looking For

• Strong hands-on Python, SQL and machine learning skills, with a track record of building and deploying models into production.
• Practical experience applying LLMs and AI agents to real-world business decisions, including evaluation, guardrails and governance.
• Strong production engineering skills across Git, testing, CI/CD, cloud platforms and model monitoring.
• A product-minded, commercially driven individual who can balance risk management with customer experience.
• Someone who enjoys building from scratch, taking ownership and translating technical solutions into tangible business results.
