Job Description

We're seeking a senior executive to join the Executive Leadership Team, working directly with the CEO on security, sovereignty, resilience and government engagement.

You will lead NEXTDC's physical security operations and critical infrastructure protection programs, own our sovereign security credentials, and represent the company with government, Defence, intelligence and regulatory stakeholders. You'll also oversee our obligations under the Hosting Certification Framework, SOCI and the Critical Infrastructure Risk Management Program.

You'll build and maintain trusted executive relationships across Defence, ASD, ACSC, ASIO, Home Affairs, law enforcement and government agencies, and represent NEXTDC in policy discussions on digital infrastructure, AI,



critical infrastructure resilience and sovereign capability.

As our executive sponsor for security assurance, you'll cover hyperscale, government, Defence, national security and regulated industry customers, translating security and sovereignty into commercial differentiation.

This is a physical security, sovereignty and government affairs role, separate from our Cyber Security function, which sits within the CTO organisation and is not part of this position.

We're happy for this role to be based in Sydney, Melbourne or Canberra.
