• Contribute to emerging initiatives including AI-driven operational capabilities

What We're Looking For:

• Strong experience with Elastic Observability, OpenTelemetry, and modern observability engineering
• Deep AppDynamics knowledge, particularly around migration and decommissioning strategies
• Expertise in Kibana, Elasticsearch, ESQL, and telemetry data analysis
• Automation-first mindset with IaC, CI/CD, and scripting experience
• Solid understanding of Site Reliability Engineering (SRE) principles
• Strong stakeholder engagement and enterprise-scale delivery experience

Why Apply?

Join a high-impact transformation program where you'll influence engineering practices across a large, complex environment while working with modern cloud-native technologies and observability tooling.

If you're passionate about reliability, automation, and building world-class observability platforms, we'd love to hear from you.

Please note that for you application to be considered, you must be based in Australia with Permanent Residency or Australian Citizenship as a minimum.
