You will work hands-on across Linux, Kubernetes, automation and day-2 operations. This role owns cluster lifecycle, node networking, storage, CI/CD, and the APIs other teams will use to create virtual machines, networks, and related lab environments for demonstrations, labs, and training on our platform. We work as a small hands-on engineering and design team at the core of the platform and we share ownership and reliability across upgrades, incidents and capacity planning with the operations team. * Build, upgrade, and operate production Kubernetes clusters, including on-premises and bare-metal environments. * Own cluster fundamentals, including Linux nodes, networking, ingress, storage, RBAC, and security baselines. * Run KubeVirt in production, including VM lifecycle, templates, scheduling, live migration, and disk attach. * Enable additional networks for VMs beyond the default pod network, including isolation between tenants or environments. * Integrate the cluster with data-centre networking and storage (CSI), including snapshot and clone workflows for VM disks. * Automate infrastructure and cluster lifecycle using Infrastructure as Code (Terraform and/or Ansible) and GitOps (Argo CD or Flux). * Contribute to Kubernetes APIs used by the product (operators, CRDs, admission, or similar) so VMs and networks can be automated without manual node changes. * Package and standardise deployments with Helm as reusable templates. * Implement monitoring, logging, and alerting (for example Prometheus and Grafana) and help define SLIs/SLOs for cluster and VM operations. * Fix across Linux, KVM/QEMU, Kubernetes, networking, and storage, and support incident response with the operations team when required. * Partner with the operations team on monitoring, alerting, and capacity planning. * Document how the platform is built, operated, and used.
