Job Description:

Remote working for UK-based candidates.

We’re hiring an Infrastructure Engineer to support a live on-premise deployment and maintenance of Kubernetes clusters using RKE2. This role is within a delivery-critical environment and requires direct experience with infrastructure as code, open-source integration, and hands-on cluster configuration.

You’ll be working across:

• Multi-node RKE2 clusters – setup, networking, RBAC, disaster recovery, and failover
• Installation and configuration of open-source components – including Prometheus, Grafana, Loki, Alloy, PostgreSQL, Rook Ceph, ActiveMQ Artemis, and Keycloak
• Kubernetes native deployment tooling - Helm and Kustomize (creation and use required), plus exposure to FluxCD pipelines
• Service integration and lifecycle management - dashboards, databases, identity, messaging, and object storage
• On-prem delivery mindset – no cloud-native shortcuts, full infrastructure control from install to runtime
• Clear, confident communication – interfacing across technical teams to ensure stable deployments and smooth handover

This role is suitable for Infrastructure Engineers who have shipped, configured, and supported Kubernetes inside real production environments.
