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 chance 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.

What We're Looking For

Essential Experience

- Robust experience delivering enterprise observability and monitoring solutions.
- Deep expertise with AppDynamics, particularly around migration, optimisation and exit planning.
- Advanced hands-on experience with Elastic Observability including:
- Elastic APM
- Kibana
- Service Maps
- Distributed Tracing
- Log Analytics
- Metrics and Alerting

- Expert-level OpenTelemetry instrumentation and collector engineering experience.
- Robust experience building and managing telemetry architectures at scale.
- Excellent Kibana dashboard design and visualisation skills.
- Advanced ESQL query-writing capabilities for troubleshooting, analysis and reporting.
- Strong automation experience across CI/CD pipelines, APIs, Infrastructure as Code and scripting.
- Practical understanding of cloud-native architectures and platform engineering principles.
- Experience implementing SRE frameworks, including SLIs, SLOs, observability-driven incident response and reliability engineering.

Desirable Experience

- Experience building Agentic AI or AI-assisted operational capabilities.
- Exposure to large-scale cloud transformation programs.
- Financial services or highly regulated enterprise experience.
- Strong governance, cost optimisation and operational risk management mindset.

Why Apply?

You'll be joining a team driving one of the most significant observability modernisation programs in the organisation, with the opportunity to influence engineering standards and platform capabilities at enterprise scale.

In return, you'll benefit from:

- Flexible and hybrid working arrangements.
- Ongoing learning and professional development opportunities.
- Industry-leading banking and employee benefits.
- Career growth within a large enterprise technology environment.
- The opportunity to work on complex, mission-critical platforms supporting millions of customers.
