We’re seeking an experienced and driven Lead Network Systems Administrator to head a high-performing team responsible for the design, security, and performance of complex network infrastructures in a mission-critical defence environment.
In this role, you will not only apply your deep technical expertise to deliver secure, high-availability infrastructure, but also lead and manage a team, providing guidance, support, and professional development to ensure operational excellence.
As the Lead Network Systems Administrator, you’ll take charge of designing, implementing, and managing robust, secure systems that support essential software development operations in a high-security setting.

You’ll be joining a forward-thinking, high-impact team working at the heart of national defence capability. We offer a secure and supportive environment where innovation, leadership, and teamwork are highly valued — and where your contribution truly matters.
Applicants are required to be Australian Citizens and be eligible to hold and maintain an Australian Defence Security Clearance. Eligibility requirements can be found at www.defence.gov.au/security/clearances.
