About the Role

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.
