About the role

L3Harris Communication Systems is a world leader in ground tactical and airborne mission communication solutions and a global provider of ground based C4 systems and transportable SATCOM terminals. We are focused on delivering advanced systems to meet the needs of our customers, uniting multiple forms of communication together, and covering communication over air, ground, sea, and space.

Left the uniform behind but still want to make a difference? This role keeps you connected to capability — in the field, alongside the people who use it.

You’ll work shoulder-to-shoulder with military units, support training, configure, deploy, and troubleshoot advanced tactical communications systems in operational conditions.

This isn’t a desk job. It’s hands-on, mobile, and mission-critical — the kind of work that keeps you close to the action without the postings cycle!

You’ll work both independently and as part of a highly skilled team, ensuring reliable performance and ongoing support of critical communication systems.

What the role will involve

The responsibilities of your role will include the following:

• Deploying to support military units across Australia (and occasionally overseas)
• Training operators on tactical radio systems and capabilities
• Configuring radios and networks to meet mission requirements
• Advising commanders and planners on communications employment
• Supporting RF and IP-based networks, including MANET systems
• Running demos, briefings and capability showcases
• Installing and integrating systems on vehicles and platforms
• Troubleshooting faults in the field — quickly and effectively
• Willingness to travel — often and sometimes at short notice

What you’ll bring

The role requires the following experience and skills:

• Current Commonwealth of Australia security clearance, minimum Negative Vetting (NV1).
• Military communications background (essential)
• Strong experience with tactical radios (operation, setup, fault finding)
• Understanding of RF networks and tactical comms architecture
• Comfortable working directly with operators and command elements
• Able to work independently, including in remote or austere environments
• Clear communicator — able to deliver concise briefings, instruction, and reporting

Bonus:

• TAE (Cert IV Training & Assessment)
• Experience with Battle Management Systems
• 8+ years in a relevant role
