You have built your career in technical cybersecurity and enjoy improving environments rather than simply maintaining them.

You understand that effective cybersecurity isn't just about monitoring alerts or responding to incidents. It's about implementing practical controls, validating security outcomes and working closely with technology teams to strengthen resilience across the organisation.

In most organisations, security controls, operating models and provider relationships have evolved over many years.

Here, you're helping establish them.

ACEREZ is building the enterprise technology environment that will support the Central West Orana Renewable Energy Zone. Cybersecurity capability needs to be embedded from the beginning, not added later.

Working closely with the Cybersecurity Manager, you'll help turn cybersecurity strategy into practical capability across enterprise technology while providing technical oversight of the managed security environment.

This is an chance to work across cloud, infrastructure, identity, operational technology interfaces, managed security services and regulatory assurance within one of Australia's most significant critical infrastructure programs.
