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 involves working within a critical delivery environment and requires experience with infrastructure as code, open-source integration, and hands-on cluster configuration.

You will be responsible for:

• Managing multi-node RKE2 clusters – setup, networking, RBAC, disaster recovery, and failover
• Installing and configuring open-source components – including Prometheus, Grafana, Loki, Alloy, PostgreSQL, Rook Ceph, ActiveMQ Artemis, and Keycloak
• Using Kubernetes native deployment tools - Helm and Kustomize (creating and utilizing), and exposure to FluxCD pipelines
• Service integration and lifecycle management – dashboards, databases, identity, messaging, and object storage
• Maintaining an on-premise delivery mindset – full infrastructure control from installation to runtime without cloud shortcuts
• Communicating clearly and confidently – interfacing with technical teams to ensure stable deployments and smooth handovers

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