Harry Maxwell are recruiting for an intermediate Systems Administrator on behalf of an established Australian engineering and construction business, with a mix of corporate and project-based operations across the country. This is a great opportunity to join a stable, well-regarded business and take genuine ownership of the systems that keep it running.

About the Role

Reporting to the Group Manager, Information Systems and Technology (IS&T;), you will take ownership of day-to-day systems administration across the business — working closely with the wider IS&T; team, project sites and external vendors to keep infrastructure, security and endpoint systems running smoothly.

This is a genuinely diverse role at the centre of the business's IT operations. Systems administration — infrastructure, network, cloud and project work — is the vast majority of the role, with a small amount of desktop support for corporate and project staff. It's suited to someone a few years into their systems administration career who wants ownership of real infrastructure, rather than someone coming purely from a desktop support background.

Key responsibilities

- Manage day-to-day operations of corporate and project IT systems, including monitoring, configuration, maintenance and repairs
- Manage backup and disaster recovery processes, restoring data within agreed timeframes
- Work with internal staff and external vendors to patch and upgrade hardware and software
- Lead third-level support, resolving issues within agreed SLAs
- Design, deploy and maintain hardware and software for remote project sites
- Manage endpoint and identity controls using Intune,



Entra ID and Defender XDR
- Support Conditional Access policy configuration and Entra PIM role management
- Support the maintenance of Essential Eight maturity level 2 controls
- Provide desktop support to corporate and project staff
- Identify and drive opportunities to improve IS&T; operations and services between remote sites and central infrastructure
- Maintain software licensing, backup procedures, virus checks and an accurate technology asset inventory

About you

- 3-5 years' experience in a Systems Administrator role, ideally in engineering, construction or a similar project-based industry
- Diploma or tertiary qualification in Information Technology preferred
- Working knowledge of the Microsoft 365 admin centre, Entra ID (Conditional Access, PIM), Intune (device/app/config management), Defender XDR and Sentinel
- Advanced knowledge of SharePoint Online administration
- Excellent interpersonal, written and verbal communication skills
- Ability to manage multiple conflicting priorities and complex problems with a strong delivery focus
- Self-motivated, well organised, with a positive can-do attitude
- Australian citizenship or permanent residency required (visa holders cannot be considered for this role)

Highly regarded
- Certifications such as MS-102 (Microsoft 365 Administrator), SC-300 (Identity and Access Administrator) or SC-200 (Security Operations Analyst)
- Exposure to Essential Eight maturity uplift and ISO 27001 control environments
- Palo Alto firewall experience
- Experience in a business of similar size and complexity, supporting both corporate offices and remote/project sites
