Platform Engineer

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.

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 Policy as Code (OPA / Gatekeeper) and enforce security, compliance, and safety guardrails

• Contribute to the Infrastructure as Code stack (Terraform) and CI/CD pipelines for cluster and platform changes

• Build and maintain observability (metrics, logs, traces) across clusters and workloads

• Partner with development teams to onboard new workloads and improve the platform's developer experience

• Solid experience with Kubernetes in a production environment, ideally on a managed cloud provider

• Hands-on experience with AWS — EKS, IAM, VPC, networking, EC2

• Strong Infrastructure as Code background, in particular Terraform

• Experience with cluster autoscaling (Karpenter, Cluster Autoscaler, or equivalent)

• Comfortable with Linux, containers, and networking at a deep level

• Strong understanding of security and multi-tenant cluster design

• Pragmatic, collaborative, and enjoy working across teams to make a platform usable

Nice to have:

• Experience with OPA / Gatekeeper or other policy-as-code tooling

• Observability stacks (OpenTelemetry, Prometheus, Grafana, Loki, or similar)

• GitOps tooling (ArgoCD, Flux) or progressive delivery

• Service mesh experience (Istio, Linkerd, Cilium)

• Experience running specialised or non-standard workloads — privileged pods, GPU/accelerator workloads, virtualisation, or other infrastructure-heavy use cases

• Contributions to open source in the cloud-native ecosystem
