About Flux IT We are a premier, Perth-based managed IT and cybersecurity provider architecting robust technical infrastructure for expanding SMB and mid-market enterprise clients both nationally and globally. Because our client environments process complex transactional data spaces and strict up-time demands, we engineer system workflows that prioritize ironclad stability, fast mitigation loops, and high-fidelity operational response every single day.
The Blueprint This is not a static tech-refresh or repetitive call-logging role. As a Level 3 IT Support Engineer at Flux IT, you will operate as a core escalation authority, actively solving complex infrastructural emergencies, configuring edge network boundaries, and deploying enterprise-grade cloud parameters. If you look at chaotic, challenging infrastructure problems as an avenue to learn, scale your technical capabilities, and mentor an expanding team, you will thrive here. No two days across our network plane look the same.

HARDCORE ENVIRONMENT STACK
Technical Capabilities Required- Hypervisors: Expert-level administration of Windows Server, VMware ESXi, and Hyper-V architectures.
- Identity & Cloud: Advanced directory configuration across Microsoft 365 core, Exchange, Entra ID (Azure AD), Teams, and SharePoint.
- Networking Core: Deep alignment with multi-vendor firewall policies, VLAN structures, routing optimization, and modern wireless perimeters.
PREFERRED ACCELERATORS
Advantageous Qualifications- Background: Direct operational background within an active MSP or multi-tenant corporate environment.
- Certifications: Validated milestones including Cisco CCNA, Microsoft MCSE, ITIL, CompTIA A+, or advanced VMware validations.
- Hardware Plane: Direct engagement with Dell bare-metal enterprise server architecture, high-capacity storage controllers, and advanced backup immutability arrays.
- We fundamentally understand that top-tier talent requires room to evolve.
- At Flux IT, we provide a genuinely flexible, supportive workspace where your career development isn't capped by bureaucracy.
- We systematically fund continuing education paths, expose our engineers to a highly diverse array of bleeding-edge technical stacks, and encourage deep strategic involvement across high-level client architectures.
- You will grow as a technical leader here.
