Ecommerce Client Executive

Salary: Competitive Plus Benefits

Location: London Store Support Centre and Home, London, EC1M 6HA

Contract type: Permanent

Business area: Nectar 360 Ltd

Closing date: 27 January 2026

We’d all like amazing work to do, and real work‑life balance. That’s waiting for you at Sainsbury’s. Everything our Nectar team does is powered and fuelled by data — and by great relationships with some of the UK’s favourite brands. The Nectar 360 team focuses on developing loyalty programmes, turning amazing data into something that makes a difference, traditional media and digital. It’s like an agency‑within‑a‑retailer, and retail media is crucial. The culture might not be what you expect either, because there’s no set‑up quite like this one. The team is a real priority because it’s connected to everything the business does and drives profitability. It’s where you can take risks, learn from them and be recognised.

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 elevate. 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.

• 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.

We are committed to being a truly inclusive retailer, so you’ll be welcomed whatever you are and wherever you work. Around here there’s always the chance to try something new—whether that’s as part of an evolving team or somewhere else across the business—and we take development seriously and promise to support you. We also recognise and celebrate colleagues when they go the extra mile and, where possible, offer flexible working.

When you join our team, we’ll also offer you an amazing range of benefits. Starting off with colleague discount, you’ll be able to get 10% off at Sainsbury's, Argos, TU and Habitat after 4 weeks. This increases to 15% off at Sainsbury’s every Friday and Saturday and 15% off at Argos every pay day. We’ve also got you covered for your future with our pensions scheme and life cover. You’ll also be able to share in our success as you may be eligible for a performance‑related target bonus of up to 5% of salary (which may vary for Nectar360), depending on how we perform. Your wellbeing is important to us too. You’ll receive an annual holiday allowance and you can buy additional holiday. We also offer other benefits that will help your money go further such as season ticket loans, cycle to work scheme, health cash plans, pay advance (where you can access some of your pay before pay day) as well access to a great range of discounts from hundreds of other retailers. And if you ever need it there is also an employee assistance programme. Moments that matter are as important to us as they are to you which is why we give up to 26 weeks’ pay for maternity or adoption leave and up to 4 weeks’ pay for paternity leave.

Please see www.sainsburys.jobs for a range of our benefits (note, length of service and eligibility criteria may apply). Please note, due to the volume of applications we receive, our roles may close early.
