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:
Nectar360 is Sainsbury’s loyalty, data and marketing services business. We use first‑party Nectar data to unlock customer understanding across Sainsbury’s and our FMCG and General Merchandise clients. You’ll join a fast‑growing, dynamic commercial team focused on combining and commercialising data and media to deliver ambitious digital growth across in‑store, onsite (e‑commerce) and offsite channels.
More about the role:
As Senior Data Strategist, you’ll be the planning expert for one or more major categories and 1–2 key FMCG clients. You’ll build insight‑led, data‑driven media strategies that align client goals with Sainsbury’s category and corporate objectives. Day‑to‑day, you’ll translate complex customer and ecommerce data into clear, persuasive plans and recommendations, partnering closely with Client Service, Analytics, Data & Insights, Campaign Media Management and Trading.
You’ll also contribute to strategic initiatives that shape our future proposition – from enhancing our Digital Trading Platform to supporting flagship programmes such as Pollen and the continued growth of offsite digital media. This is a highly visible, client‑facing role where consultative selling and ‘live planning’ in meetings are part of how you create measurable impact.
More about you:
You are an exceptional data planner who can handle large, complex datasets and distil them into simple, compelling stories for senior stakeholders. You’re confident presenting, influencing and bringing cross‑functional teams together to solve client and category challenges. You’re comfortable with ambiguity, proactive in identifying opportunities and generous in sharing your expertise to upskill colleagues and support the wider team.
Experience in retail media is highly valued, and we welcome applicants from agency‑side senior data/media planning backgrounds. Familiarity with loyalty, market research and ecommerce data – and how targeting, segmentation and profiling drive direct and digital media – will help you hit the ground running.
Essential criteria:
• Ability to translate complex customer/ecommerce data into clear, client‑ready strategies and plans.
• Proven skill in aligning recommendations to both client outcomes and retailer/category objectives.
• Demonstratable experience of presenting to senior stakeholders and influencing cross‑functional teams.
• Evidence of leading significant projects (e.g., platform improvements or cross‑team initiatives) to measurable outcomes.
• Practical knowledge of targeting, segmentation and profiling techniques for direct and digital media.
We are committed to being a truly inclusive retailer, so you’ll be welcomed whoever 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. Here are some of them:
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 20% 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, interest free car loan of up to £10k, 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, you will also be eligible for private healthcare too.
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).
