Insight Manager - Business Performance in London

Join Sainsbury's Retail & Digital Insights team, the home of customer and market understanding that powers decision‐making across our stores, digital channels and brands. We connect the dots between customer behaviour, market performance and commercial outcomes to shape best‐in‐class experiences across Food, General Merchandise and Clothing. Working closely with colleagues in Supply Chain, Commercial, Finance, Property Analytics, Channel Operations and eCommerce, we turn data into clear, actionable insight that helps leaders make faster, smarter choices for customers—today and for the future.

As Insight Manager – Business Performance, you'll be the go‐to expert on continuous data sources (Panel and EPOS) and the custodian of a single, reconciled view of performance across channels, regions and clusters. You'll lead the creation of regular insight packs and the periodic Business Performance packs for Retail leadership forums, triangulating customer, financial, operational and research data to explain the 'why' behind trends and highlight where to act. You'll provide business context in forums such as RLT and pre‐pulse, supporting Directors of Stores and channel leaders with decision‐ready narratives and clear options.

You'll partner across Retail & Digital to enhance our in‐store customer feedback programme ("iCare"), define and track KPIs for service initiatives, and surface emerging customer and market trends that shape our omni‐channel strategy. You'll lead cross‐functional reviews (e.g., Christmas, price investment, loyalty and promotions), manage day‐to‐day priorities and agency resources, and champion adoption of self‐serve tools (e.g., SIP, Nielsen, Kantar) so teams can access and interpret insight with confidence. While your centre of gravity will be Food & GM in Retail channels, you'll bring a holistic, omni‐channel perspective that spans Sainsbury's and TU.

You're comfortable being the single point of contact for senior stakeholders, translating complex data into concise stories that inform choices and drive action. You're source‐agnostic, confident working across continuous panel, EPOS, CSAT, financial and operational datasets, and you know when to commission new work with analytics and agency partners. You plan ahead, balance day‐to‐day needs with forward‐looking exploration, and you're pragmatic—testing, learning and scaling what works.

You enable others: encouraging self‐serve, raising data literacy, and embedding consistent standards for quality and timeliness. You collaborate in a true HIVE mentality—joining up insight across commercial, brand, digital and customer experience—to create a single, shared picture of performance and opportunity.
