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.

We're looking for a Senior Full Stack Engineer to join our Application Platform team in Manchester, on a hybrid basis. You'll be one of the first product engineers on dunnhumby's new continuous-deployment paved road, building a customer-facing analytics product end-to-end and showing the rest of engineering what "production-ready on the platform" looks like.

What we expect from you:

Senior-level experience building and running production services in C# / ASP.NET Core and TypeScript / Next.js / React — with working knowledge of the other side and an appetite to grow into both.
Comfortable owning a service on Kubernetes — deployments, probes, autoscaling, NetworkPolicies, RBAC — and debugging real failures from kubectl alone.
Solid working knowledge of Kubernetes operators and CRDs — you understand reconciliation loops, custom resources, and how operator-driven infrastructure differs from imperative provisioning.
Hands-on with at least one of GCP (GKE, Cloud SQL, Pub/Sub, Secret Manager) or Azure (AKS, Azure DB for PostgreSQL, Key Vault), and willing to learn the other.
Clear written communication — RFCs, ADRs, runbooks, PR descriptions other engineers can act on.

Nice to have:

Crossplane experience — authoring Compositions, CompositeResourceDefinitions, or custom providers.
GitOps fluency with ArgoCD and Helm, and CI/CD authorship in GitLab.
Building custom Kubernetes operators with the Operator SDK or Kubebuilder.
Service mesh experience (Istio or Linkerd).
Prior experience migrating a product from bundled releases to continuous deployment.
Backstage or internal developer portal contributions.

Responsibilities:

Shape clear, testable acceptance criteria with Product and Design
Build and own end‑to‑end products across .NET services, TypeScript frontend, PostgreSQL, and GitOps deployment
Design scalable backend systems (APIs, event handling, clean architecture patterns)
Deliver high‑quality frontend experiences with accessible components and strong data/state management
Work with cloud‑native, declarative infrastructure (Kubernetes, Crossplane, CRDs)
Maintain high standards across testing (unit, integration, contract) and code quality
Apply strong security practices across backend and frontend systems
Build meaningful observability (tracing, logging, SLOs) focused on real user impact
Take a cost‑aware approach to scaling and resource usage
Participate in an on‑call rotation once ramped up
Use AI‑assisted development tools (e.g. Copilot, Claude) effectively in day‑to‑day work
