What we're looking forWe're looking for someone with strong hands-on experience across Microsoft infrastructure who has operated at Senior Infrastructure Engineer, 3rd Line Engineer, Systems Engineer or a similar level.
You'll ideally bring strong experience across Azure, Active Directory/Entra ID, Microsoft 365, Intune and Windows Server, alongside broader infrastructure knowledge such as VMware, backup/DR and endpoint security.
You'll need to be comfortable owning technical problems through to resolution, working within structured change processes and communicating confidently with both technical teams and business stakeholders.
Experience delivering infrastructure projects, migrations, platform improvements or modernisation initiatives would be particularly valuable.
