- Design, implement and support enterprise infrastructure across Microsoft Azure, Microsoft 365 and integrated SaaS platforms.

- Manage and enhance cloud security, identity and endpoint management solutions including Entra ID, Conditional Access, Intune and Microsoft Defender.

- Lead infrastructure, cyber security and technology improvement projects from design through to implementation and operational handover.

- Design and support Azure Virtual Desktop (AVD) environments and associated technologies.





- Maintain and optimise enterprise networking environments including Cisco Meraki, Ubiquiti, VPN and SD-WAN solutions.

- Act as a senior technical escalation point, proactively identifying risks, resolving complex issues and driving continuous improvement.

- Mentor junior team members and contribute to technical standards, documentation and operational best practices.

- Participate in occasional after-hours work for planned critical changes (infrequent).
