Customer Campaign Analyst

We’re looking for a collaborative and analytical Customer Campaign Analyst to join our Customer Value Management (CVM) team. In this role, you’ll help maximise value from our customer base through targeted, data‑led marketing campaigns. Working within an agile delivery model, you’ll contribute to accurate campaign performance reporting, meaningful analysis, and clear tracking of the value delivered through CVM activity.

You’ll help ensure our campaign strategies are insight‑driven, continuously improved, and aligned with wider business objectives.

Key Responsibilities

• Manage ongoing reporting and insights for Broadband and PAYG squads, including regular performance updates and in‑depth post‑campaign reviews.
• Maintain and enhance self‑serve Tableau dashboards for X‑Sell and PAYG campaigns.
• Oversee a Python‑based automation process that keeps dashboards updated and reduces manual workload.
• Identify opportunities for test‑and‑learn initiatives (e.g., offers, channels, messaging) grounded in data.
• Support the design, execution, and analysis of structured testing frameworks, including A/B tests.
• Contribute to developing new Tableau dashboards that support reporting on our AEP journey‑based campaign approach.
• Monitor live campaigns to ensure data accuracy, correct volumes, and appropriate delivery labels.
• Proactively escalate and help resolve data quality or campaign‑build issues.
• Input segmentation codes into campaign briefs to enable robust analysis.
• Advise on control group approaches to ensure statistically reliable results.
• Build effective working relationships across teams, including Digital, to support knowledge‑sharing and reduce siloed working.
• Lead regular performance discussions with squads to review results and share insights.
• Maintain the CVM Insights Library to ensure historical post‑campaign analysis is organised, accessible, and used to inform future activity.

• Experience in customer marketing or customer value management within a B2C environment, with a clear understanding of CRM and CVM practices.
• Proficiency in SQL, R, or Python for data querying and analysis, along with experience using reporting and visualisation tools such as Tableau or Power BI.
• Ability to design and evaluate statistically robust testing frameworks—such as A/B tests—to assess and improve campaign performance.
• Skilled at translating analytical findings into clear, practical recommendations that inform decision‑making and support ongoing strategy.
• Comfortable learning new tools and methods, with an open and proactive approach to developing technical and analytical skills over time.
