About the Role
Nectar360 is Sainsbury's loyalty, data and marketing services business, built around the power of Nectar first-party data to unlock a deeper understanding of customers across Sainsbury's brands and our FMCG and GM supplier partners. Within Nectar360, the Commercial team brings data and media together to create relevant, digital-first solutions that help clients and the business grow in a fast-moving market where customer understanding is a true differentiator.
As a Data Strategist, you will sit within one of the fastest-growing and most dynamic areas of the business, helping to drive profit growth through Nectar360’s data-driven media and digital offering—in and around store, onsite (Sainsbury’s), and offsite, including our Digital Trading Platform (DTP). You will be responsible for how we combine and leverage data to create compelling strategies that resonate with customers and deliver commercial impact.
The role is hybrid and reports to a Client Planning Director. Day to day, you will lead client account brand planning aligned to Sainsbury’s corporate, marketing and category objectives, translating insight into clear recommendations. You will partner closely with analytics to deliver evaluations that tell an effective story of performance and the value of first-party data.
You will also act as a category expert for selected categories and key FMCG client accounts, playing a leading role in major cross-business events involving Nectar360, Marketing and Trading—managing stakeholders across varying seniority and agendas to deliver campaigns that drive trade and meet broader objectives.
The Nectar360 team focuses on developing loyalty programmes, turning data into impactful solutions across traditional media and digital. The culture encourages taking risks, learning from them and being recognised. This team is a real priority as it is connected to everything the business does and drives profitability.

Experience
- Demonstrable experience leading insight-led brand or campaign planning aligned to wider business, marketing and category objectives, with clear outcomes and measures of success.
- Evidence of creating data-driven proposals including data selection, segmentation/profiling approach, and compliant processes in line with customer data guidelines.
- Proven ability to partner with analytics to deliver evaluation and effectiveness storytelling, communicating the impact of first-party data in a clear narrative for stakeholders.
- Track record of presenting to and influencing clients and senior stakeholders using structured materials (e.g., PowerPoint) and sound numerical reasoning (e.g., Excel-based analysis).
- Experience working with loyalty or CRM data to plan and optimise targeted communications, using segmentation and profiling techniques for direct marketing/loyalty campaigns.

About you
You are a strategic thinker with strong data literacy and a genuine passion for data-driven marketing and understanding customer behaviour. You bring a blend of shopper marketing knowledge, digital channel understanding, and the ability to build trusted relationships—using evidence and insight to influence decisions with clients and senior stakeholders. You are comfortable shaping complex information into simple, persuasive narratives, whether in proposals, presentations, or evaluation read-outs. You are organised and effective at planning and prioritising multiple workstreams in a fast-moving environment. You take ownership as a custodian of data within planning, strategy and targeted communications, proactively spotting opportunities using client context, Nectar insights and market trends to create new value. You also contribute to team capability by mentoring colleagues, sharing best practice, and helping to strengthen data planning techniques, client partnership skills and commercial thinking across Nectar360.

We are committed to being a truly inclusive retailer and welcome candidates from all backgrounds. While specific qualifications are not detailed, a strong foundation in data-driven marketing, analytics, or related disciplines is implied.
