About the Team

Join the Business Performance arm of our Customer Insight team, where we partner with divisions across Sainsbury’s to put customers at the heart of every decision. Our team supports senior stakeholders and decision makers, providing actionable customer insights that drive strategic choices and shape the future of our business. You’ll collaborate with a range of Sainsbury’s and agency teams, ensuring a unified view of performance and the highest standards of data accuracy. This is a fantastic opportunity to be part of a dynamic, fast-paced environment where your work directly influences the direction of one of the UK’s leading retailers.

More About the Role

As an Insight Executive in Business Performance, you’ll focus on two key pillars: Insights Generation and Data Integrity. Day-to-day, you’ll develop a deep understanding of customer, market, and commercial data—ranging from CSAT and Customer Mindsets to EPOS and Panel data. You’ll create impactful recommendations by confidently overlaying different data sources, joining the dots to deliver clear, actionable insights.

You’ll support and lead strategic projects across Sainsbury’s brands, building strong relationships with stakeholders such as Commercial Operations, Investor Relations, and Corporate Affairs. Your work will include managing market data queries, validating reports, refreshing data hierarchies, and rolling out self-serve tools to the business. Regular reporting on Sainsbury’s performance will be a core part of your remit, with a focus on ensuring data integrity and consistency across all outputs.

More About You

You’re passionate about data integrity and thrive on analysing information from varied sources to uncover the ‘so what’. Strategic thinking and a hypothesis-led approach help you break down complex problems and deliver clarity to the business. You’re comfortable working with large data sets in a retail or FMCG context, and you know how to bring together first and third-party data, collaborating closely with agencies.

Attention to detail, organisation, and project management are among your strengths. You’re adept at pulling and validating data from different sources, ensuring it’s fit for purpose, and you can explain and interpret outputs in a simple, engaging way. You’re a confident communicator, able to address complex data challenges and drive continuous improvement, and you possess excellent cross-functional collaboration skills to streamline processes and enhance delivery performance.

Essential Criteria

• Ability to analyse, explain, and interpret data or outputs in a clear and engaging manner, providing actionable recommendations.
• Advanced proficiency in Excel and strong grasp of PowerPoint.
• Experience managing stakeholder data queries and data validation processes.
• Proven experience working with large data sets in a retailer or FMCG context, with demonstrable use of market or customer data (e.g., Kantar, Nielsen, CSAT).
• Ability to implement and manage self-serve data tools and platforms.
