We’re looking for a hands‑on Infrastructure Engineer to support a hybrid Microsoft environment, with a strong focus on BAU, ticket resolution, and operational stability.

• Support Active Directory / Entra ID, including users, groups, and access management
• Troubleshoot issues across Windows Server, M365, and cloud infrastructure
• Write and maintain PowerShell scripts for automation and admin tasks
• Support Intune / endpoint management where required
• Work closely with service desk and wider IT teams to ensure smooth operations

Required Skills & Experience

• Strong experience in a BAU / support‑led infrastructure role
• Good working knowledge of Microsoft Azure (portal‑based admin)
• Solid PowerShell skills (scripting, automation, troubleshooting)
• Experience with Microsoft 365 (Exchange Online, Teams, SharePoint)
