Platform Engineer

About the team Kubernetes is a core part of CDP — the internal platform that powers and standardizes most of Coretura’s engineering workloads. Kubernetes is the backbone of all of it: development environments, CI/CD pipelines, build systems, and a large-scale virtualised test platform on AWS. As CDP evolves, we'll operate one or more clusters regardless of final architectural direction, whether cloud-agnostic or built around AKS, EKS, or GKE. We work closely with security, DevOps, and platform to set the standards for how Coretura runs software in the cloud, including Infrastructure as Code, Policy as Code, observability, and cost governance. What you'll do This is a senior role at the intersection of Kubernetes engineering and platform engineering. You'll work hands-on with the cluster — node provisioning, networking, upgrades, scaling — and you'll also think a layer up: what abstractions should the rest of engineering see, what defaults should be safe, what should be self-service vs. paved-road vs. off-limits. We need someone who's comfortable in both areas. You'll work at two levels. Hands-on: building, scaling, and hardening EKS clusters — node provisioning, networking, upgrades, security, the deep cluster work. And one layer up: defining the abstractions the rest of engineering consumes — namespaces, RBAC, ingress, secrets, paved-road defaults, self-service patterns. You think about Kubernetes as a platform that other teams build on, not just infrastructure to operate. You've designed abstractions, paved roads, or self-service patterns that other engineers actually used. You will: Design and operate production Kubernetes clusters on AWS (EKS), including upgrades, scaling, and reliability Drive dynamic node provisioning (Karpenter), including mixed instance types, Spot strategies, and cost optimisation Build and own the platform abstractions — namespaces, RBAC, networking, ingress, secrets, and shared services — that internal teams rely on Implement Pol
