Digital Senior Client Manager in London

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.

Nectar360’s Digital Media team is building the UK’s most powerful insight‑and‑data‑led media services capability, connecting some of the nation’s favourite brands with customers to help them live well for less. We’re investing significantly in our Digital Trading Platform (DTP) and data assets to plan, target and measure campaigns across display, social and TV. You’ll join a close‑knit, ambitious team within Nectar360’s Commercial function, partnering with major FMCG and general merchandise brands and their agencies from our Holborn Store Support Centre.

You will own a defined agency patch, acting as the face of Nectar360’s digital proposition to your portfolio. Your focus is simple and meaningful: create and convert a healthy pipeline, deliver revenue and profit against target, and deepen relationships with both warm and new agency contacts. You’ll shape how our offering shows up in market—crafting compelling pitches and materials—and you’ll represent us confidently at all levels.

Day to day, you’ll qualify opportunities, align commitments with our Digital Trading team’s capacity, and provide timely feedback loops so campaigns are implemented to plan. You’ll contribute market and agency insight into new DTP propositions, and report regularly on pipeline health and performance. The role reports to the Digital Client Director and sits at the centre of a supportive ecosystem that includes training programmes, mentoring and industry‑recognised development via IAB courses and internal learning hubs.

You bring strong commercial acumen in digital media and a working knowledge of the media agency landscape. You’re highly organised, comfortable navigating change, and able to manage multiple workstreams without losing sight of the outcome. Your written and verbal communication is clear and persuasive, enabling you to explain data‑driven propositions and next steps to clients, agencies and internal stakeholders alike.

You’re proactive and resilient, able to operate independently while collaborating effectively across trading, product and commercial colleagues. You take accountability for results, act with integrity, and stay hands‑on—especially when it helps a client, a campaign or the team move faster.
