The Role and the Team

This is a brand new Principal role, reporting to the Data Director. You'll be a subject matter expert and influential voice on experimentation and product insight, setting the standard for how we test, learn and scale what works. Beyond your own analytical output, you'll serve as a technical and strategic anchor for the Product Data Science team, mentoring colleagues, shaping best practice, and ensuring the quality and impact of data analytics work across the organisation. This role is the natural progression for an experienced and senior professional and is designed to enable the activation of deep specialism, whilst influencing and helping set the strategic direction of the focused areas as a senior contributor.

What You'll Do

• Own the strategic vision, roadmap and culture for experimentation and test and learn, setting company-wide standards, tooling and governance in partnership with Engineering
• Lead the design and development of complex, high-impact data products and models that inform product strategy and member experience
• Own and evolve our product and digital analytical practice, including instrumentation strategy, funnel and engagement work and product KPI frameworks
• Partner with Product Managers and engineering colleagues to understand member behaviour across our app, web and transactions, and turn it into clear, actionable insight
• Champion one source of truth by owning the definition of key metrics and supporting consistent methodology across the business
• Share findings with clarity and conviction with senior audiences, including our executive team, using data storytelling to support better choices
• Mentor Product Data Scientists, run code and methodology reviews and support new colleagues to settle in and thrive
• Own experimentation capability-building across Blue Light Card teams, training and enabling non-specialist teams to run rigorous tests independently

What You'll Bring

• Extensive experience working with data in an analytical and scientific capacity, ideally in a digitally native technology environment
• Experience leading an experimentation programme or testing tool, applying statistical modelling and experimentation methods to real business problems
• Strong proficiency in SQL plus Python or R
• Experience with BI platforms such as Lightdash, Looker or Tableau, with the storytelling skills to bring insight to life
• The ability to turn complex findings into clear business narratives and present data-led arguments with confidence to senior stakeholders
• Experience mentoring or coaching colleagues, with the interpersonal skills and growth mindset to raise capability and influence without direct management authority
• Experience building roadmaps for data products, balancing multiple priorities with sound judgement
• Experience with dbt would be a bonus, but is not essential
