Overview
Join to apply for the Systems Administrator role at BAE Systems Australia.
About The OPPORTUNITY: Think of this role as being the guardian of our private cloud. Your day-to-day will involve keeping infrastructure healthy and drama-free: maintaining and updating custom images, applying patches, performing firmware updates, managing an on-prem domain and making sure everything runs smoothly behind the scenes. You may also work with the Infrastructure & Operations teams on BAU tasks, automating repetitive work and providing support when needed. This position can be based out of our Adelaide or Melbourne office with flexible work arrangements such as a 9-day fortnight and hybrid work environment on offer.
We recognise the role as part of a broader mission to deliver projects of global and national significance, contributing to a culture that values wellbeing, inclusion and ongoing learning.
Key Responsibilities
- Keep servers healthy: Admin Linux (Ubuntu/RHEL) & Windows systems
- Tame the hybrid beast: Manage and troubleshoot Private Cloud & On-Prem Domain
- Be the fixer: Respond when Infrastructure/Ops teams report issues
- Automate everything: PowerShell, Bash, Ansible, Terraform – your choice
- Security and compliance: CIS hardening, patching, and maintaining secure, auditable systems
About You
You're a SysAdmin at heart — experienced with Linux and Windows servers and private cloud platforms (Azure Stack, VMware, or similar). You understand patching, image management, and firmware TLC, and you take pride in keeping systems rock solid. You bring a mix of hands-on skills and problem-solving and have some automation experience with PowerShell, Bash, Ansible, or Terraform. You can work across teams, share knowledge, and provide BAU support. You care about security, stability, and future-readiness—and you’re comfortable contributing with a sense of humor. If you don’t tick every box but are excited about the role, you’re encouraged to apply.
As Defence security clearance is required for this role, applicants must be Australian citizens and either possess or be eligible to obtain and maintain appropriate clearances.
