The Opportunity

An exciting opportunity has arisen to lead a large-scale enterprise observability transformation within one of Australia's most recognised financial institutions.

This role sits at the centre of a strategic initiative to modernise monitoring and observability capabilities across the organisation, transitioning from AppDynamics to Elastic Observability and establishing OpenTelemetry as the enterprise standard.

You'll drive the technical direction of the migration, help shape modern SRE practices, and build scalable observability foundations that improve reliability, resilience and operational efficiency across a complex cloud and hybrid technology landscape.

This is an ideal opportunity for someone who enjoys combining hands-on engineering with technical leadership, automation and platform strategy.

What You'll Be Doing

• Lead the enterprise-wide migration from AppDynamics to Elastic Observability, ensuring a seamless transition with enhanced visibility and monitoring capabilities.
• Design and implement OpenTelemetry-first instrumentation standards across applications and platforms.
• Build and optimise telemetry pipelines covering logs, metrics, traces and distributed observability.
• Drive adoption of Site Reliability Engineering (SRE) practices, including SLI/SLO-driven monitoring and alerting frameworks.
• Develop automation solutions using Infrastructure as Code, scripting and CI/CD pipelines.
• Create reusable observability patterns, self-service tooling and engineering standards.
• Partner with application, platform, cloud and engineering teams to uplift observability maturity across the organisation.
• Lead the decommissioning of legacy AppDynamics tooling, agents and licensing.
• Mentor engineers and SRE teams while producing documentation, runbooks and operational standards.
