Position Overview

The Senior Data Scientist, Government will be the primary quantitative specialist within the dedicated analytics team supporting the UK Government account. A central pillar of this role is ownership and development of WPP Media's Government Benchmarking Database – a strategic asset that will underpin campaign measurement & planning across the account. Working closely with the wider analytics team, the Senior Data Scientist will translate analytical challenges into well-designed, rigorous statistical solutions – taking ownership of the technical approach, model development and delivery once the problem has been scoped collaboratively.

• Government Benchmarking Database
  • Take ownership of the Government Benchmarking Database, including responsibility for maintaining and evolving its underlying structure as the tool develops.
  • Support the wider analytics team in effectively accessing and leveraging the database, including producing advanced query templates and delivering training to ensure analysts can work with the data confidently and independently.
  • Lead the scoping and delivery of new analytical capabilities within the platform, including the development of models that estimate expected campaign lift for a given level of spend based on historic performance data.
  • Ensure outputs from the benchmarking platform are surfaced in a clear and intuitive way, taking a lead role in how modelled results and benchmark data are visualised for planning and client teams.
• Analytical Solution Design & Delivery
  • Work closely with the wider analytics team to understand and scope analytical challenges arising from UK Government campaign activity, contributing to the design of appropriate quantitative approaches to address them.
  • Take ownership of the technical execution of agreed analytical solutions – selecting and applying the most suitable statistical or machine learning methodologies, building and validating models, and delivering outputs that are robust and actionable.
  • Own the end-to-end development of statistical and machine learning models – including forecasting models, attribution frameworks, response curve modelling and audience/behaviour change models – using Python or R.
  • Conduct regular audits of current analytical infrastructure and capabilities, prioritising improvements based on effort-versus-return.
  • Synthesise outputs from multiple analytical workstreams into coherent performance narratives – clearly articulating what is working, what isn’t and what future actions are recommended.
  • Collaborate with planning and activation teams to ensure model outputs and analytical learnings are fed back into future planning cycles.
  • Contribute to target-setting and forecasting for future campaigns, drawing on historical performance trends and modelled relationships.
  • Develop understanding of non-marketing performance drivers to contextualise model outputs and provide a broader view on maximising campaign effectiveness.
• Technical Development & Innovation
  • Proactively explore and evaluate innovative statistical methodologies, data sources and tooling that can enhance the analytical capability of the government team.
  • Contribute to the development of scalable, reproducible analytical pipelines and tools that can be reused across the government account.
  • Build business cases for incremental investment in advanced analytical solutions, grounding recommendations in modelled evidence.
  • Participate in relevant industry bodies and stay current with developments in data science, causal inference and media measurement best practices.
• Team Leadership & Development
  • Manage and mentor junior analysts and data scientists on a day-to-day basis, fostering their technical growth and development.
  • Contribute to thought leadership promoting excellence in data science and analytical rigour within WPP Media and the wider industry.
