IT Systems Administrator

The IT Systems Administrator is instrumental in administering, securing, and operating a hybrid IT estate that spans on-premises infrastructure and a fully cloud-based Microsoft 365 environment. Covering end user support, virtualization, cloud identity, endpoint management, networking, and security, this is a full-spectrum role that balances day-to-day operational support with strategic project execution.

This role spans both systems administration and end user support. The ideal candidate owns and administers the platforms directly Entra ID, Intune, Microsoft 365, VMware, and the broader infrastructure while also handling L1 and L2 support tickets as part of daily responsibilities. The advantage of a true sysadmin in this seat is that they are not just troubleshooting symptoms, they understand and control the systems underneath. When project work is light, additional focus shifts to end user support alongside the helpdesk team.
