Job Expectations

Position Title: Senior Expert Systems Engineering, Security and AI Enablement

Build your career and Australia’s future. Not many people can say they are working on building Australia’s future. With us you’ll be doing just that, leaving a legacy for all Australians. Plus, there’s equal employment, great training, and true flexible working arrangements.

A bit about your role

As the Senior Expert Systems Engineering, Security and AI Enablement, you will act as a senior technical authority for platform security, DevSecOps and responsible AI across Enterprise DSO. You will define reusable standards, patterns and guardrails across SaaS platforms, internally built applications, integrations and cloud-hosted services, while providing technical assurance for complex cross-domain initiatives. You will lead the transition from manual ClickOps practices to secure, automated engineering using CI/CD, configuration as code, automated testing and repeatable deployment patterns. You will also build and scale reusable AI capabilities, including agents, skills, tool integrations, evaluation approaches and human approval controls, helping teams move from experimentation to secure, observable and supportable enterprise solutions. Working through technical authority rather than direct line management, you will coach engineering teams, influence senior stakeholders and help resolve systemic security, control and technical‑debt issues across the platform portfolio.

A bit about you

The ideal candidate brings strong expertise in enterprise systems engineering, security, cloud and DevSecOps, with the ability to apply secure engineering practices across SaaS platforms, applications and integrations. You’ll have hands‑on experience with agentic AI tools such as GitHub Copilot and Claude Code, including building secure, testable and observable AI workflows with appropriate human oversight. You’ll be comfortable improving automation and DevSecOps practices, assessing AI opportunities across value, security, privacy and risk, and working collaboratively with engineering, architecture, cyber security and business stakeholders. A relevant degree or equivalent professional experience is required, with related security, cloud, architecture or AI qualifications considered an advantage.
