Job description

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.

dunnhumby employs nearly 2,500 experts in offices throughout Europe, Asia, Africa, and the Americas working for transformative, iconic brands such as Tesco, Coca-Cola, Nestlé, Unilever and Metro.

dunnhumby Network Alliance

dna (dunnhumby Network Alliance) 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.

The Role

Own the architecture that makes dna work in the real world, across dunnhumby, Kevel, retailers and publishers. This is enterprise architecture and customer-facing solutioning in a single seat: set the patterns, then prove them on live opportunities and partner integrations.

What You'll Be Doing

Own dna's target-state architecture across platform, data, integration and security, and the guardrails that keep it coherent as partners are added.
Turn business, product and partner requirements into end-to-end solution designs covering integration patterns, data flows, deployment models and non-functional requirements.
Lead the technical side of retailer and publisher onboarding, from discovery through to a working integration, so each new partner lands faster than the last.
Define reusable platform patterns that reduce bespoke, client-specific builds and improve scalability, consistency and cost-to-serve.
Act as the senior technical voice in partner and client conversations, including with Kevel, shaping credible options and explaining the trade-offs behind them.
Feed delivery reality back into product and engineering, spotting where recurring needs should be productised, standardised or simplified.

What You'll Bring

Strong enterprise, solution or platform architecture background across cloud, data and integration environments.
AdTech and MarTech fluency: ad servers, SSPs and DSPs, identity, bidding, event pipelines, tagging and closed-loop measurement.
Proven experience integrating third-party platforms and partner ecosystems at scale, including API and data-contract design.
Experience with clean rooms, privacy-enhancing technologies and data collaboration across organisational boundaries.
Customer-facing solutioning, technical pre-sales or proof-of-concept experience, with strong communication to commercial and leadership audiences.
The judgement to balance long-term architectural intent with pace, shipping practical designs under real delivery constraints.
