Observability Engineer

What’s the role?

As an Observability Engineer, you will play a key hands-on role in transitioning Westpac’s enterprise observability capability from AppDynamics to Elastic Observability, using OpenTelemetry as the standard for telemetry collection and instrumentation.

You will help shape and execute the technical approach for vendor decoupling, rebuild and enhance existing observability use cases in Elastic, and introduce automation across deployment, validation and decommissioning activities. You will also embed Site Reliability Engineering practices by moving from traditional health-rule monitoring towards SLI and SLO-based observability and alerting. Working across a large and complex enterprise environment, you will provide technical leadership, develop migration runbooks and self-service capabilities, and help improve the reliability, scalability and operational effectiveness of Westpac’s observability platforms.

Key responsibilities will include:

• Decomposing existing AppDynamics implementations and rebuilding the required APM, logging, metrics and tracing use cases in Elastic Observability.
• Implementing OpenTelemetry collectors and automating their deployment, configuration and validation.
• Developing SLI and SLO-based alerting and embedding observability quality checks into CI/CD pipelines.
• Automating integrations with event and incident management systems and supporting the safe decommissioning of AppDynamics agents, configurations and licences.
• Providing technical guidance, migration runbooks and self-service assets to support engineering teams across the organisation.

What do I need?

• Extensive hands-on experience with AppDynamics APM, including the ability to assess existing implementations and support migration and exit planning.
• Advanced experience with Elastic Observability, including APM, distributed tracing, logs, metrics, service maps, dashboards and alerting.
• Strong knowledge of OpenTelemetry and modern observability practices, including SLIs, SLOs, incident diagnostics and service reliability.
• Experience using Infrastructure as Code, CI/CD pipelines, APIs and scripting to automate platform deployment, configuration and operational processes.
• Strong communication and stakeholder-management skills, with the ability to provide technical leadership and collaborate across a large enterprise environment. Experience with ES|QL, platform governance, cost optimisation and risk management will be highly regarded.
