Highly Desirable * Automotive, used-car, classifieds or dealer-network experience, including B2B marketplace dynamics. * Databricks and dbt experience, including Spark for large-scale feature engineering. * Experience delivering explainable models through a CRM such as Salesforce. * Marketplace pricing, dynamic pricing or price-index development. * Exposure to LLMs and generative AI, with an understanding of where they add genuine value. * Experience mentoring or managing Data Scientists, or establishing a Data Science function. * Power BI or equivalent for surfacing model outputs to business users. ## Description Reporting into the Director for Data, this is Cazoo's inaugural Data Science role: a senior, hands-on individual contributor who will establish Data Science as a discipline, set its standards and deliver its first production models, with the opportunity to grow the team over time. This is not a research role. You will work alongside Data Engineering & ML Ops to productionise models, using our evolving Databricks platform, and partner with Analytics and BI to ensure outputs drive commercial decisions. You will own the data-science roadmap, prioritising opportunities such as dealer churn propensity, Customer Lifetime Value, vehicle pricing, stock recommendations, buying propensity and Next Best Action, alongside Marketing Attribution and Marketing Mix Modelling. As the function grows, you'll help hire, develop and mentor Data Scientists, beginning with a planned mid-level hire. If you'd rather ship a well-understood model today than a perfect one next year, and are as comfortable explaining a propensity score to an Account Manager as you are tuning it, you'll feel right at home. Establish Data Science at Cazoo * Define the Data Science operating model, from identifying and sizing opportunities through to model development, deployment, monitoring and measuring business value. * Set technical standards for code quality, reproducibility, model governance and explainability across the wider data function. * Work with Data Leadership to own and prioritise the data-science roadmap, aligned to Cazoo's commercial goals and focused on measurable value. * Shape ML tooling on Databricks alongside Data Engineering & ML Ops, including feature pipelines, experiment tracking, deployment and monitoring. Prove the value, every time * Frame every model around a measurable hypothesis, using holdouts, uplift and control groups to demonstrate commercial impact for Cazoo and its dealers. * Contribute to business-wide quarterly OKR planning, ensuring Data Science initiatives have clear hypotheses, measurement frameworks and expected value. * Balance rigour with practicality, choosing the simplest reliable model that delivers measurable results. Be the Data Science partner the business needs * Keep dealers at the centre, building data products that help them sell stock faster, improve pricing and generate higher-quality leads. * Partner with Commercial, Account Management, Finance, Product and Marketing to turn model outputs into actionable business decisions. * Work closely with the Analytics CoE to inform model development and embed outputs into dealer reviews and commercial playbooks. * Mentor Analysts in statistical and machine-learning methods, raising Data Science capability across the business. * Represent Data Science at sprint playbacks and Leadership Team reviews.
