Job summary

CXC seeks a Lead Platform Engineer to oversees technical operations for an on-premises infrastructure and container platform, from bare metal to workloads. You will own runbooks, automation, and GitOps pipelines, and line-manage engineers while handling L3 escalation during major incidents.

You will coordinate cross-functional teams, manage on-call processes, and ensure platform reliability with strong focus on scalability and auditability.

Qualifications

• Scale-enabled server/infrastructure provisioning and lifecycle management using bare-metal tooling (MAAS/Foreman).
• End-to-end node lifecycle workflows: drain, reassign, reprovision, validate, return to service.
• Container image lifecycle: build, scan, sign/approve, promote and replicate OCI images in a registry (Artifactory/Harbor).
• Kubernetes administration across multiple clusters: lifecycle, upgrades, CNI, CSI-backed storage.
• Strong networking fundamentals: TCP/IP, DNS, routing, load balancing, VLANs, Ethernet troubleshooting at scale.

Responsibilities

• Own technical standards and runbook estate, ensuring versioning and reviews stay current.
• Own automation and GitOps pipelines, including Git-backed config, Ansible, and ArgoCD-managed Kubernetes state.
• Own rota and on-call escalation across coverage bands, balancing rotation with risk.
• Line-manage senior engineers and coordinators, setting objectives and developing talent.
• Act as L3 escalation point and incident commander for major incidents, restoring service.

Job description

Leads technical operations for a newly built, large-scale on-premises infrastructure and container platform, from the as-built reference set through to the runbook estate. Owns the rota and on-call escalation chain, and line-manages the engineering team. Acts as the technical anchor between design and live operations, able to speak to the platform end to end, from bare metal through to the workloads running on it, and the person the team turns to when something goes seriously wrong.

Key responsibilities

• Own technical standards and the operational runbook estate, keeping the versioning and review procedure enforced so it stays accurate rather than decaying into shelfware.
• Own the platform's automation and GitOps pipelines, including Git-backed configuration, Ansible playbooks and ArgoCD-reconciled Kubernetes state, so change across the estate is auditable and repeatable.
• Own the rota and the on-call escalation chain across multiple coverage bands, balancing fair-share rotation against real operational risk.
• Line-manage senior engineers, engineers and coordinators, setting objectives, holding the competency bar, and developing them toward the next level.
• Act as the L3 escalation point and incident commander for major incidents, owning the technical response until service is restored.

Essential skills and experience

• Server and infrastructure provisioning and lifecycle management at scale: imaging, inventory, node role assignment, and firmware/OS patching, using a bare-metal provisioning platform (for example MAAS, Foreman or a comparable tool).
• Comfortable owning node lifecycle workflows end to end: drain, reassign, reprovision, validate, return to service.
• Container image lifecycle management: build, scan, sign/approve, promote and replicate OCI images through a registry pipeline (for example JFrog Artifactory, Harbor or equivalent).
• Real, current Kubernetes administration across multiple purpose-built clusters (for example separate admin, workload and platform-services clusters), covering cluster lifecycle, upgrades, CNI, and CSI-backed persistent storage.
• Strong networking fundamentals: TCP/IP, DNS, routing, load balancing, VLANs and Ethernet troubleshooting at scale.
