Candidate Profile

• 5+ years experience coordinating enterprise virtualisation platforms.
• Strong hands‑on experience with VMware vSphere/ESXi or equivalent.
• Experience handling VDI deployments at scale (Omnissa Horizon or VMware Horizon preferred).
• Experience managing core infrastructure (AD, DNS, SCM) in virtualised environments.
• Proficient in automation tools and scripting languages such as Ansible, Terraform, PowerCLI, Python, and others.
• Strong problem‑solving abilities across compute, network, and storage.
• Experience with patching, upgrades, and capacity planning.
• Strong understanding of security architecture, hardening practices, and risk mitigation within virtualised environments.
• Experience supporting semiconductor or HPC/EDA environments.
• Familiarity with GPU‑accelerated VDI or compute workloads.
• Knowledge of observability tools (Prometheus, Grafana, Splunk).
• Understanding of high‑performance networking (10/25/40/100GbE, RDMA, etc.).
• Experience with crafting sandbox environments for security and DR testing work.
• Understanding of Kubernetes platforms (Tanzu, OpenShift, Rancher, etc.).
