Job description

We're an Adelaide-based technology company delivering centralised infrastructure, monitoring, and connectivity services to a large network of client sites across South Australia. Our technology team supports a large, distributed operational environment and is currently in an active period of infrastructure transformation and platform modernisation.

The role

You'll be the hands-on engineer responsible for our on-premises, cloud, and network infrastructure across a multi-site environment. You'll own infrastructure decisions, work through complex problems independently, and know when to elevate. This is not a helpdesk role.

What you'll do

• Administer and maintain server, virtualisation, storage, and backup infrastructure
• Manage network infrastructure and security appliances across a large number of remote sites
• Maintain Microsoft 365 and on-premises Active Directory environments
• Support the secure client-facing portal used for real-time reporting and data access
• Respond to infrastructure incidents and drive root-cause resolution
• Contribute to patching, change management, and documentation
• Support cybersecurity controls and respond to audit and compliance requirements
• Work alongside senior technical staff and external vendors on project delivery

What we're looking for

• Solid hands-on experience with Windows Server and Active Directory
• Backup and recovery experience
• Network firewall and WAN administration across multi-site environments
• Microsoft 365 administration including Exchange Online, Teams, and Entra ID
• Comfortable working in a regulated environment with documentation and change control disciplines
• Strong troubleshooting instincts and the ability to work through problems methodically

Nice to have

• Scripting skills (PowerShell, Python, or similar)
• Familiarity with ITIL frameworks or formal change management processes
• Experience in a regulated or compliance-heavy industry

Who suits this role

Someone who prefers solving real problems over ticket queues. You take ownership, communicate clearly when something's wrong, and don't wait to be told what to do. You're comfortable working in a small team where your contribution is visible.

Why choose us

We're a small, stable technology company with a technically interesting environment and real responsibility from day one. We provide centralised infrastructure and connectivity services relied on by clients across the state, so reliability and attention to detail matter.
