About the Role

As the Data Analyst, you will be responsible for delivering insight that drives improvements across the full commercial ecosystem spanning customer experience on, retailer investment effectiveness, marketing and sales performance, and the broader post-purchase, onboarding and promotional landscape.

This role requires strong analytical capability, expertise in data modelling and SQL, and the ability to translate complex commercial questions into dashboard logic and actionable recommendations.

  • Design, build and maintain a marketing and sales performance dashboard in Looker Studio, underpinned by Big Query, combining sell-out sales data, market volume and share data, and campaign activity logs.
  • Define the underlying data model, transform source files and design the reporting layer to support consistent, scalable KPI delivery.
  • Identify and quantify the impact of retailer investment, including uplift in sales and market share during campaign periods.
  • Analyse correlations between campaign activity and commercial performance to determine which marketing levers are most effective.
  • Measure and report on halo effects across products and retailers resulting from promotional and campaign activity.
  • Define and calculate key performance metrics including uplift, baseline, market share, activity intensity and halo effects.
  • Work with GFK or other syndicated market data sources to enrich performance analysis with market volume and share context.
  • Customer Experience & Digital Analytics
  • Conduct analysis of the current customer experience, including user behaviour, content and campaign performance and conversion pathways.
  • Benchmark key customer journeys against competitor websites to identify gaps and opportunities.
  • Provide regular insight into paid promotions, post-purchase experience and customer satisfaction trends.
  • Support planning, optimisation and operational management of post-purchase and onboarding experience.
  • Analyse content utilisation, engagement and drop-off points, and recommend enhancements.
  • Collaborate with HQ and local teams on onboarding content production and implementation.
  • Support feature management including evaluation, testing performance and monitoring adoption, with ongoing analysis of content effectiveness and customer experience updates.
  • Reporting, Dashboards & Stakeholder Insight
  • Build and maintain dashboards, reports and ad hoc analyses across customer experience, onboarding, e-commerce, retail performance and promotion activity.
  • Translate data into clear insights that guide decision-making within marketing, CX, digital and commercial teams.
  • Present findings clearly to stakeholders at all levels, ensuring insight is embedded in planning and operational processes.
  • Use platforms like GWI to build digital personas and audience profiles that support broader marketing planning.
