The business also builds capabilities that can be used for a wide range of applications in both traditional and non-traditional environments; providing leadership in the advancement of technological modernisation of complex enterprises within Government.

The Opportunity

As a Site Reliability Engineer within our AGO GEO SPACES program, you'll play a key role in delivering and sustaining technology solutions that support critical national security outcomes. Working in a secure, highly regulated environment, you'll help ensure the reliability, performance and resilience of mission-critical platforms while collaborating with engineering and operational teams to maintain exceptional service standards.

• Enhance automation, infrastructure-as-code and CI/CD practices across the environment, partnering with development and platform teams to enable consistent, secure and reliable deployments.

About You

You are someone who enjoys solving complex operational challenges and takes a thoughtful, collaborative approach to improving system reliability. You bring a combination of infrastructure expertise, automation capability and a continuous improvement mindset, enabling you to contribute effectively within high-availability environments supporting critical business outcomes.

• Experience working as a Site Reliability Engineer, Systems Engineer or in a comparable infrastructure-focused role supporting production environments.
