The Opportunity

This is a pivotal role within a high-performing IT function that supports large-scale enterprise infrastructure.

• Managing Intune and SCCM for endpoint onboarding, policy deployment, and software packaging.
• Overseeing server patching processes and infrastructure monitoring, including WSUS/AUM configuration and third-party update scheduling.
• Supporting high-priority incident resolution, root cause analysis, and the documentation of best practices and knowledge articles.
• Driving continual service improvement and supporting major infrastructure and cloud transformation projects.

• Ideally a minimum of 7 years' experience in systems administration or infrastructure engineering.
• Strong knowledge across Active Directory, Windows Server, Microsoft 365, Exchange Hybrid, Azure, PowerShell scripting, and endpoint management tools like Intune and SCCM.
• Experience supporting high-availability environments, with a focus on security, resilience, and user experience.
• Excellent problem-solving skills and a proactive approach to automation and process improvement.
• Previous experience leading or coaching junior team members.
• Professional certifications in Microsoft technologies or cloud platforms (highly desirable).
