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.
More about the role
- You will be working in one of the fastest growing and dynamic areas of the business, driving significant growth from Nectar360’s data-driven General Merchandise media and digital offering – in and around store, onsite (Sainsburys & Argos e-Commerce), above the line and offsite (including our proprietary platform, Pollen)) monetisation.
- Using customer data you’ll create impactful, strategic recommendations to deliver long term positive change for our clients (suppliers and agencies), total Argos and Nectar. You’ll be responsible for the creation, presentation and evaluation of insight led media activation recommendations and client plans across the Argos and Sainsbury’s channel toolkit. You’ll work with some of the biggest and best tech, toys, electrical and home brands in the world.

More about you
- You’ll need to be a master of customer and digital data literacy from your experience in GM/ FMCG/ retail environments and be able to successfully mould complex data from various sources (inc. analytics) into a compelling story that inspires others to act based on your recommendations.
- You’ll have extensive experience in targeting, profiling and demographic audience segmentation in a digital environment.
- You will have great digital retail media knowledge (ecommerce and offsite ideally) and evidence of your ability to manage and positively challenge multiple senior stakeholders whilst maintaining long term relationships.
- You’ll be motivated by innovation and ambiguity and relish the opportunity to continue to build the Planning capability and expertise within the Argos and General Merchandise sectors so Nectar360 can continue to lead the industry.
- You’ll act as the subject matter expert for data-led media planning, monetisation and act as the customer champion for cross-functional initiatives (i.e. with Product/Tech teams), with strong project management skills to drive projects forward.
- You’ll have experience of developing and mentoring others around retail media and data planning techniques (inc. use of ecommerce data, customer data and testing methodologies), client relationship skills and commercial acumen
Essential criteria:
- Ability to translate complex customer/ecommerce data into clear, client‑ready strategies and plans.
