The role

Due to continued growth, we are seeking a L2 Systems Administrator to join our Managed Services team in Brisbane. In this role, you will take the lead in standardising, configuring, and automating provisioning, remediation, updates, and roadmaps for desktop environments using Microsoft Intune, SCCM, Autopilot, and related tools.

You’ll be the go-to expert for resolving complex and high-impact technical challenges.

Key Responsibilities

• Develop and maintain standards and best practices for OSD/SOE, Intune, and application deployment across large enterprise environments.
• Design, audit, and optimise end-to-end deployment solutions, from AutoPilotbased provisioning to SCCM-driven SOE rollouts.
• Ensure patch compliance and system updates across client environments using Intune update rings or SCCM.
• Lead pilot rollouts, driver updates, application packaging, and image management.
• Act as an escalation point for complex issues from the Managed Services and Operations teams.
• Support application lifecycle management via Windows Store and SCCM.
• Work closely with cross-functional teams including Network, Product Engineering, and Automation to create and maintain service catalogue items and automation scripts.
• Help clients transition toward a modern hybrid infrastructure, recommending the best approach (Intune/AutoPilot vs SCCM/SOE) on a per-device basis.

Key skills and experience required:

• 5+ years of experience in Endpoint Management within enterprise environments.
• Expert-level knowledge of Wintel environments and a broad range of infrastructure technologies.
• Proven experience with SCCM, including SOE builds, device updates, and application deployment.
• Advanced proficiency with Microsoft AutoPilot and Intune MDM for modern device management.
• Strong understanding of automation capabilities within SCCM and Intune, including API integrations and scripting (e.g., PowerShell).
• In-depth knowledge of patch management using Intune, SCCM, or similar endpoint management tools.
• Familiarity with Tanium or similar endpoint security platforms.
• Experience acting as the final escalation point for complex, high-impact technical issues.
• Strong skills in root cause analysis and problem resolution.
• Solid ITSM queue management abilities and a disciplined approach to ticket handling.
• Experience conducting technical workshops and knowledge sharing sessions with both clients and internal teams.
• Willingness and ability to travel to client sites for hands-on support when required.
• Relevant industry certifications (such as Microsoft, ITIL, Tanium, or equivalent) are highly desirable.

Note: the role requires an ability to obtain NV1 Clearance.

As part of our hiring process, you will be required to undertake a technical test and a National Criminal History Check.
