The Role
Our Business Analytics team is growing! We’re looking for a Senior Business Analyst to join our team in London.
In this role you will help turn our Rewards and Core data into clear, trusted answers, building reporting and analysis that the business actually makes decisions on, and learning to do it AI-natively from day one.
Key Responsibilities
Own the vertical commercial reporting end to end, measuring monthly gross profit, reconciling it to Finance and presenting numbers the board can trust
Run and evolve the analytics stack: the semantic layer, per-brand P&L, LTV cohorts and Single Customer View
Turn retention economics into decisions, using cohort and CRM uplift analysis to guide where budget is invested
Partner directly with commercial, CRM and Finance stakeholders to answer the questions that move the vertical
Set the reporting standards and mentor junior analysts as the pod grows
About You
Senior analytics experience owning a commercial vertical end to end, with strong SQL and BigQuery and confident dashboarding in Tableau and via LLMs
Extensive experience building reporting pipelines and, just as important, challenging them: interrogating the taxonomy, definitions and formulas rather than accepting them as given
AI native in how you work: you build and ship reporting with LLM tooling as a default way of working, not an add-on
Grounded in retention and lifetime value economics, cohort analysis and CRM driven measurement, not only acquisition
Commercial, board facing judgement: you can turn analysis into a recommendation and defend a number to senior stakeholders
You thrive when working as part of a team
Comfortable in a fast-paced environment
What You’ll Get
Private Health Care (Bupa)
Hybrid Working (3 days in office)
Travel Insurance
Competitive Base Salary
Company Bonus Scheme
Paid for AI Subscription (Claude / ChatGPT / Gemini)
Market-Leading Training Programme
