Who the Client Is
A modern, cloud-forward enterprise with a mixed on-prem/Azure footprint, focused on uptime, security-by-default and pragmatic automation.
What You’ll Do
-
Administer and optimise VMware clusters (performance, capacity, patching).

5–7+ years’ systems admin experience across Windows/VMware/M365/Azure.
-
Solid networking (TCP/IP, VLANs, VPNs), security basics and PKI.
-
Proven PowerShell automation; scripting for scale and repeatability.
-
Experience with Veeam (or similar) and DR testing.
-
Clear communicator; structured, detail-driven and service-oriented.

Relevant certs advantageous (e.g., VCP, AZ-104/305, MS-102).
What Success Looks Like

Predictable costs across Azure/M365 with usage and savings tracked.
-
Up-to-date runbooks and a knowledge-enabled support team.
Realistic Preview: You’ll juggle BAU and projects in a live environment—after-hours maintenance windows and urgent escalations happen. The upside: visible impact on uptime, security and developer velocity.
