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.
