Offer description

About the role:

Our client is a large Commonwealth department. Within its CIO Division, the ICT Operations Branch manages all ICT services across the organisation. The End User Services section is responsible for the department's communication and collaboration platforms, including the standard operating environment (SOE), corporate device management, Exchange, Exchange Online and Microsoft Teams.

Responsibilities:

You will manage and enhance the department's hybrid Exchange environment, including ongoing migration of Exchange mail data to Exchange Online and maintenance of Enterprise Vault archiving. You will investigate and resolve complex technical problems across the messaging stack, produce technical documentation, represent the team at project meetings and facilitate technical workshops as required. This is a Canberra-based onsite role; remote working will not generally be suitable for this opportunity.

* Maintain Exchange Server infrastructure and Enterprise Vault archiving solution
* Migrate mail data, groups and archive data to Exchange Online
* Investigate and resolve complex technical problems across the hybrid Exchange stack
* Develop migration approaches, decommissioning plans and as‐built/design documentation
* Cross‐skill team members and support related teams including the service desk
* Represent the team at project meetings and facilitate technical workshops as required

Essential criteria:

* Expert knowledge of Exchange Server, Exchange Online and hybrid Exchange deployments, including implementation, upgrades and day‐to‐day management in a complex multi‐forest environment
* Proven experience in Exchange migrations including to Exchange Online, cross‐forest and from legacy Exchange versions
* High‐level Exchange troubleshooting skills including mail flow, mail gateway technologies and on‐premise/cloud‐based resource connectivity
* High‐level knowledge of Windows Server fundamentals (Active Directory, DNS, DFS) and Group Policy configuration including AGPM
* Experience with Australian Government IT cyber security processes including ISM, Essential 8 and ACSC hardening guides
* Strong experience writing technical documentation including design documentation and standard operating procedures
* You must hold a current Baseline security clearance at commencement – this is non‐negotiable as the role requires immediate access to PROTECTED information and systems

Desirable:

* Experience with Arctera Enterprise Vault, Microsoft Purview Information Protection (MPIP), Microsoft Intune MDM and Intune policy
* Experience with broader Microsoft 365 services

This is a hands‐on infrastructure team within a large department's ICT Operations Branch. The End User Services section manages critical communication and collaboration platforms and values deep technical expertise. You will work alongside other infrastructure specialists in a supportive environment focused on operational excellence and knowledge sharing.

Benefits:

* Long‐term contract opportunity (up to 3 years with extensions)
* Complex hybrid Exchange environment with genuine migration and modernisation work
