Technical Consultant: Systems & Infrastructure Engineer

Aryon Pty Ltd | Brisbane, QLD | Full time | Hybrid, with client site work across South East Queensland

About Aryon

Aryon is a Queensland-based professional and managed IT services firm. We help clients make their technology more secure, resilient and easier to manage through sound architecture, disciplined delivery and trusted long-term advice.

Our work spans cloud, infrastructure, networking, cyber security and modern workplace capability. We are particularly robust in education, health, the public sector, not-for-profit and mid-market environments where reliability, clarity and risk reduction matter.

At Aryon, systems administrators are more than ticket resolvers. We value people who understand the client environment, diagnose issues methodically, implement practical improvements, document their work properly, communicate clearly and take ownership through to resolution.

The opportunity

We are looking for an experienced Systems Administrator to join our Managed and Professional Services team, supporting and improving a diverse range of client environments.

This is a hands-on, client-facing role with responsibility across day-to-day administration, complex incident resolution, technical maintenance and planned improvement work. It suits someone who enjoys solving difficult problems, reducing recurring issues and taking ownership beyond a conventional service desk role.

The ideal candidate will bring strong capability across Microsoft 365, Azure, Windows Server, identity, virtualisation, backup and endpoint management. Experience in an MSP or other multi-client environment will be highly regarded.





What you will do

· Administer and support Microsoft 365, Azure, Entra ID, Windows Server, Active Directory, Group Policy, virtualisation, backup and endpoint environments.

· Own complex incidents and service requests through investigation, resolution, documentation and client communication.

· Monitor platform health, capacity, backup status, security alerts and patch compliance, and address risks before they become service-impacting problems.

· Plan and deliver maintenance, upgrades, migrations, remediation and small infrastructure improvement activities.

· Manage user lifecycle, identity, access, permissions and authentication controls in line with approved procedures and least-privilege principles.

· Troubleshoot issues across servers, cloud services, endpoints, applications, networking and security controls, working with specialists where required.

· Maintain accurate technical documentation, configuration records, knowledge articles and handover notes in Aryon’s documentation systems.

· Communicate clearly with clients about impact, progress, risk, options and next steps.

· Work with consultants, project managers, account managers and other engineers to transition project outcomes cleanly into managed support.

· Contribute to operational standards, automation, reusable procedures,



problem management and technical knowledge sharing.

· Mentor less experienced engineers where appropriate while remaining accountable for your own commitments.

What you will bring

· Practical systems administration experience in an MSP, systems integrator, consulting or comparable multi-site environment.

· Strong hands-on capability across Microsoft 365, Azure, Entra ID, Windows Server, Active Directory, Group Policy and PowerShell.

· Experience administering virtualisation, backup, endpoint management, patching, monitoring and remote management platforms.

· A sound understanding of DNS, DHCP, TCP/IP, VPNs, firewalls and network troubleshooting.

· Experience with security controls including multi-factor authentication, conditional access, endpoint protection, privileged access and vulnerability remediation.

· The ability to investigate methodically, identify root causes and implement fixes that reduce repeat incidents.

· The ability to write clear technical documentation that other engineers can trust and clients can rely on.

· Strong client communication skills, including the ability to explain technical risk, options and operational impacts in plain language.

· A delivery mindset: you manage commitments, surface risks early, follow change control and see work through to a clean outcome.

· A professional approach to quality, time recording, escalation and handover.

· Unrestricted work rights in Australia. Depending on the client engagement, you may also need to complete background screening or obtain a national police check, Queensland Blue Card or other client-specific clearance.
