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 varied 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.
