Full 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, or 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 Lin
