  • Contribute to system builds, automation, and continuous improvement initiatives
  • Ensure compliance with Defence security standards and accreditation requirements
  • Provide support to live simulation exercises and operational events
What We’re Looking For
  • Extensive experience within Defence or Defence-aligned environments (ESSENTIAL)
  • Strong hands-on experience with Linux system administration (enterprise environments)
  • Experience working in highly secure, classified environments
  • Understanding of ITIL-based service management
  • Exposure to virtualisation (VMware/KVM) and enterprise storage solutions
  • Ability to operate in high-pressure, mission-critical scenarios
Why This Role?
  • Work on nationally critical Defence platforms
  • Be part of a highly skilled, specialised technical team
  • Engage in cutting-edge simulation and training environments
  • Long-term, secure program of work in Bungendore
