Full Job Description
Overview As a Senior Systems Engineer, you will lead the organisation’s transformation from a VMware-based environment to Red Hat OpenShift Virtualisation. This role is responsible for the full migration lifecycle, as well as the day‑to‑day operation, optimisation, and maintenance of Virtual Machines (VMs) running on OpenShift. You will serve as a senior technical resource, providing deep expertise in virtualisation, Linux, Kubernetes/OpenShift, and enterprise infrastructure. Job Description Duties and Responsibilities: Infrastructure Design: Assist with the design of Bare Metal OpenShift clusters optimised for virtualisation, ensuring high performance for compute-heavy VM workloads. Modernisation & Migration: Lead the end-to-end migration lifecycle from VMware vSphere to OpenShift. This includes leveraging the Migration Toolkit for Virtualisation (MTV), performing pre-migration discovery, and executing "Warm Migrations" to minimise downtime for critical business stateful workloads. Storage Management: Experience configuring Portworx as the storage provider on top of Pure Storage. Backup & DR: Experience with managing backup and DR within Red Hat OpenShift environments. Assisting the DR team in configuring run books for Client DR Testing. Operational Excellence: Manage VM-specific "Day 2" operations, including Live Migration, node maintenance/draining, and high-availability (HA) scheduling. Optimize & Maintain: Proactively monitor our systems with CheckMK, manage storage on Pure Storage and HPE. Troubleshoot & Resolve: Act as a final escalation point for complex technical issues, performing deep-dive root cause analysis and collaborating with support teams to ensure timely resolution. Collaborate & Innovate: Work closely with a team of skilled engineers to share knowledge, improve processes, and evaluate emerging technologies. Provide Critical Support: Participate in a rotating on-call schedule to provide after-hours support for critical infrastructure. Flexibility:
