The Role:
The MQ-4C (Triton Unmanned Aircraft System) team in Edinburgh (SA) is expanding.
Northrop Grumman Australia is seeking a Cyber Security GRC Lead to take ownership of the governance, risk and authorisation activities underpinning one of Australia's most advanced Defence capabilities.
Triton is a first-of-type ISR platform for the ADF, operating across complex systems and classifications. Cybersecurity isn't a tick-box exercise, it needs to be clearly defined, documented, justified and maintained throughout the system lifecycle.
This role sits at the centre of that process. You'll lead the development and maturity of the security artefacts, assessments and governance activities that support Authorisation to Operate (ATO), helping ensure Triton systems remain secure, compliant and trusted.
You'll inherit a solid foundation with established frameworks, templates and artefacts already in place. The opportunity is to take ownership, uplift their maturity, and help shape a professional suite of security documentation that supports the Triton program.
This role is Adelaide-based (RAAF Edinburgh). Australian Citizenship and an NV1 clearance are required to be considered.

You'll lead how cyber risk is assessed, documented and managed, ensuring Triton systems maintain their ATO and continue to meet Defence security requirements.
