About the Role
We are seeking a Senior Data Scientist to join our award-winning Data Science team. This is a hands-on, high-ownership role where you will partner with various business teams to develop and deploy ML and AI solutions that enhance our two-sided marketplace. You will translate ambiguous business problems into production-ready solutions, delivering them end-to-end.
Responsibilities
- Lead data science initiatives from problem framing through to deployment, monitoring, and iteration, ensuring robust, scalable, and performing solutions.
- Design and build LLM-powered solutions for business value, applying them alongside classical ML.
- Connect work directly to business outcomes, building models to improve marketing efficiency, pricing, or recommendation engines.
- Move fast to test ideas, define success metrics, validate honestly, and iterate.
- Partner with Commercial, Marketing, Product, Finance, Engineering, and Operations stakeholders to understand problems and communicate findings.
- Contribute to shared best practices, documentation, and ways of working to raise the bar for the data science function.
- Drive continued adoption of AI capabilities for efficiencies and automation.
Requirements
- Commercial Mindset: Prioritize business impact and understand how models connect to revenue, efficiency, or customer outcomes.
- Stakeholder Partnership: Proven ability to work with commercial, marketing, and product stakeholders, translating business problems into solutions and communicating technical details clearly.
- Sound Judgement: Navigate the tooling landscape with clear eyes, knowing when classical ML, GenAI, or simpler solutions are appropriate. Strong instincts for scalability, reliability, and explainability.
- Marketplace or Two-Sided Platform Experience: Understanding of supply/demand dynamics and how data science creates leverage in a marketplace context.
- Proven ML Experience: Strong track record of building, deploying, and maintaining ML models in Python in a production environment.
- Full-Lifecycle Delivery (MLOps): Comfortable delivering the end-to-end production lifecycle without relying on a dedicated ML engineering team.
- GenAI & LLM Expertise: Hands-on experience building LLM-powered solutions that deliver measurable business value.
- Technical Depth: Solid experience in a cloud ML environment with software engineering principles (version control, code reviews, unit testing, containerisation).
- Quantitative Rigour: Strong foundation in statistical evaluation and experiment design, with the ability to define and defend success metrics.
