Why You'll Love It At AC3

We make technology real, not robotic. We're the crew keeping Australia's critical systems online and secure 24/7. Our Site Reliability team is expanding, and we're looking for a Linux (RHEL) Admin who's ready to step beyond maintenance mode and into engineering evolution.

If you love RHEL, live for automation, and get a buzz from solving the unsolvable, this is where you belong.

What You'll Be Doing

  • Running and refining AC3's RHEL environments, provisioning, patching, and performance tuning.
  • Automating everything with Ansible, Puppet, Bash, or Python.
  • Keeping mission-critical systems humming for government and enterprise clients.
  • Collaborating across Cloud, Security, and Platform squads, you'll never be siloed.

What You'll Bring

  • 3+ years in Linux Systems Admin, with deep RHEL experience.
  • Hands-on with automation/orchestration tools (Ansible, Puppet, etc).
  • Scripting chops in Python, Bash, or Ruby.
  • A problem-solver's mindset - curious, collaborative, and calm under pressure.
  • Australian citizenship (Baseline Security Clearance required).

Why AC3?

We're a homegrown tech company that blends enterprise scale with start-up energy. You'll get autonomy, mentorship, and exposure to major projects, all inside one of Australia's most awarded tech cultures.

  • You'll grow fast.
  • You'll learn daily.
  • You'll be heard.
  • You'll make an impact that matters.

Ready to Do More Than Just 'Keep the Lights On'? Apply now and bring your Linux passion to a team that's redefining what secure, human centered tech looks like in Australia.

AC3 - Make technology real.
