About the Role
dunnhumby is the global leader in Customer Data Science, partnering with the world's most ambitious retailers and brands to put the customer at the heart of every decision. We combine deep insight, advanced technology, and close collaboration to help our clients grow, innovate, and deliver measurable value for their customers. Our clients include transformative, iconic brands such as Tesco, Coca-Cola, Nestlé, Unilever, and Metro.

dunnhumby Network Alliance (dna) is an open, collaborative Retail and Commerce Media service designed to unify a fragmented market and unlock growth for brands, agencies, and retailers. Operating as a neutral layer across multiple retail partners, dna brings together audiences, inventory, and intelligence, enabling a single, simplified point of entry to cross-retailer media at scale. Built in partnership with Kevel and powered by dunnhumby's data and expertise, dna connects brand and performance across the full customer journey, delivering more transparent, consistent, and effective outcomes in an increasingly complex media landscape.

As Senior Campaign Manager, you will help deliver campaigns across the dna ecosystem with consistency, care, and a strong eye for quality. This role is about making complex campaign delivery feel seamless—coordinating internal and external stakeholders, processes, and details to ensure smooth activation.

What You'll Be Doing
You will work with brands, retailers, creative, product, operations, and measurement teams to deliver campaigns from briefing to completion, and help build scalable processes and operational models to continually improve delivery and maintain high standards. You will own end-to-end delivery of dna campaigns, including campaign setup, activation, and in-flight management to ensure delivery against agreed budgets and targets. You will ensure campaign readiness and execution by validating assets, formats, tracking, and policy compliance, while coordinating brands, internal teams, and retailers to deliver campaigns on time. You will own campaign status and issue resolution, maintaining clear visibility on delivery, resolving problems, and escalating where required. You will own quality assurance and campaign documentation so delivery is consistent and compliant throughout the process. You will identify opportunities to improve ways of working and simplify delivery across repeat campaign activity. You will operate effectively in a fast-paced, evolving environment, managing multiple campaigns and parallel workstreams, adapting to changing priorities and taking ownership of work beyond core campaign management where required. You will help scale a significant new entry in market.

What You Can Expect From Us
We offer a comprehensive rewards package typical of a leading technology company, including flexible working hours and your birthday off. You will benefit from investment in cutting-edge technology reflecting our global ambition, combined with a nimble, small-business feel that encourages experimentation and learning. We live diversity and inclusion every day with thriving networks supporting gender equality, LGBTQ+ pride, family, accessibility, and wellbeing. We are committed to providing an inclusive recruitment process and flexible working arrangements to support your work/life balance.

Experience
Proven experience delivering digital ad campaigns end to end, with a strong operational focus on consistency, accuracy, pace, and follow-through. Experience managing multiple campaigns and stakeholders simultaneously in a fast-paced environment. Strong understanding of retail media, including retailers, inventory, and audience partners.

About You
Highly organised and operationally strong with excellent coordination skills to keep internal and external teams aligned without unnecessary complexity. Detail-oriented, especially regarding documentation, quality assurance, and delivery accuracy. Comfortable working with ambiguity and motivated to improve processes and drive efficiency. Interested in retail media and excited by the opportunity to help shape and build an industry-leading proposition.

Qualifications
No specific qualifications required; however, relevant experience in campaign management, digital advertising, or retail media is highly desirable. A proactive attitude and willingness to take ownership and drive results are essential.
