Network Team Lead

Job Description ASC is Australia’s submarine company. We built the Royal Australian Navy’s Collins Class submarines, sustain them, and are now delivering their Life of Type Extension to increase the boats’ service lives. We have also been selected by the Australian Government to sustain and jointly build the nation’s conventionally armed, nuclear-powered submarines – the largest and most complex industrial undertaking in Australia’s history. Our work is interesting and meaningful, contributing directly to Australia’s national security. We offer rewarding roles that provide the opportunity to grow your career, and the flexibility to balance life and work. A career at ASC is like no other, delivering a deeper purpose we can all be proud of.

You’ll lead a small, skilled team, drive strategic planning, and keep our network governance sharp and up to date. From mentoring and yearly planning to jumping in on the on-call roster and solving complex technical puzzles, this role is perfect for someone who’s hands-on, highly technical (bonus points for Cisco and Palo Alto experience), and thrives on leadership, innovation, and root cause analysis. If you love networks and want to make a real impact, this is your moment. Responsibilities Lead and mentor the network team, managing workloads and supporting professional development. Ensure secure, reliable operation of LAN, WAN, wireless, and perimeter security infrastructure. Conduct site surveys and develop quotes for new or upgraded network capabilities. Maintain and update network governance documentation and knowledge bases. Drive network modernisation initiatives, including automation and cloud integration. Plan and coordinate upcoming work and contribute to yearly infrastructure planning. Participate in the on-call roster and lead incident response and root cause analysis. Ensure compliance with regulatory frameworks. About You Proven experience in enterprise network design, implementation, and support. Strong technical expertise in routing, switching, wireless, and perimeter security. Demonstrated leadership and mentoring experience in a technical team. Excellent troubleshooting and root cause analysis skills. Familiarity with ISM and other cybersecurity frameworks. Strong communication, planning, and stakeholder engagement skills. Ability to manage competing priorities and lead by example in a dynamic environment. Experience with Cisco and Palo Alto technologies (preferred but not essential).
