• Administer and optimise VMware clusters (performance, capacity, patching).
• Manage Active Directory / Entra ID (users, GPOs, DNS / DHCP, hybrid identity, PKI).
• Operate Microsoft 365 (Exchange Online, SharePoint, Teams) and hybrid Exchange.
• Build / support Azure (VMs, storage, networking); enforce security and cost guardrails.
• Run Veeam backups / replication; test recoveries to agreed RPO / RTO.
• Oversee Cloudflare (DNS / WAF / CDN) and core network dependencies.
• Automate with PowerShell; maintain CMDB and clean documentation.
• Perform health checks, patching and upgrades; follow ITIL for incidents / changes.
• Provide 3rd-line support and deliver improvement projects with peers.

What You Bring

• 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

• Stable, well-patched platforms with clear observability and low incident rates.
• Fast, reliable restores; DR tests passed to target RPO / RTO.
• Automated routines reducing toil and mean-time-to-resolve.
• 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.
