Senior Data Scientist
Location: Central London (Hybrid, 3 days in office)
Position Type: Contract outside IR35
A high-growth, market-leading online automotive marketplace is hiring a Senior Data Scientist to join an award-winning central data science team.
Operating across both sides of a massive two-sided consumer and commercial platform, this role focuses on designing, building, and deploying production-grade machine learning and generative AI systems that directly influence revenue, pricing, marketing efficiency, and operations.
Key Responsibilities
- Take full end-to-end ownership of ML and AI solutions from problem framing through to production deployment, monitoring, and iteration
- Deliver production-ready code and manage model lifecycles independently without relying on a dedicated ML engineering team
- Build and scale GenAI and LLM-powered systems for practical operational automation, search, and content understanding
- Design pricing models, propensity signals, and recommendation engines across marketing and core platform products
- Partner directly with Commercial, Product, Operations, and Marketing leadership to translate complex business problems into structured technical solutions
- Champion robust engineering standards, documentation, and experimentation best practices across the team
