Nectar 360 - Ecommerce Client Executive

About the team

Join Nectar360, the retail media and loyalty business within Sainsbury’s, where we’re focused on delivering an exceptional digital experience for customers shopping on Sainsbury’s Online. You’ll be part of one of the fastest‑growing, most dynamic areas of the business, helping to power supplier‑funded campaigns across Sainsburys.co.uk, the Sainsbury’s App and our On‑Demand channels so brands can connect with customers at the moments that matter. 

More about the role

As an eCommerce Client Support Executive, you’ll manage end‑to‑end delivery of supplier‑funded media activations—planning, trafficking and QA through to reporting—ensuring every campaign lands on time and to plan across our digital channels. You’ll be the central point of contact for delivery queries, troubleshooting issues swiftly, and maintaining our shared team inbox so colleagues and clients get clear, timely answers. 

You’ll create weekly and ad‑hoc performance reports using Adobe Analytics and the Sainsbury’s Insight Platform, translate findings into actionable recommendations, and keep supplier activation packs and web pages up to date. You’ll also support proposal development for Food eCommerce, maintain accurate financial admin with 100% billing accuracy, and build collaborative relationships across Nectar360 and Sainsbury’s teams to keep work moving smoothly. 

More about you

You’re organised, methodical and comfortable managing multiple workstreams in a fast‑moving environment with changing priorities. You take responsibility for your work, keep yourself current on processes and communications, and show strong attention to detail—especially when working in Excel and with analytics tools. You communicate clearly with internal and external stakeholders and know when to escalate. 

You plan and prioritise effectively, work well both independently and as part of a team, and bring a positive, proactive approach—anticipating next steps, spotting risks and opportunities, and taking action. You’re committed to ongoing personal development and open to evolving ways of working that improve how we deliver. Experience in Marketing/Digital, working with commercial teams or suppliers, or familiarity with media plans/analytics is a bonus, but not essential. 

Essential criteria Experience of managing multiple workstreams in a demanding environment. Experience of working with ambiguity and changing situations. Proficient in the use of Excel. Effective communicator, with experience of working with internal and external stakeholders.
