Create your best future and join Westpac as a Site Reliability Lead Engineer.

What’s the role?

This role sits within the Customer Platform unit, which owns a critical enterprise platform delivering customer data capabilities across onboarding, servicing, and product origination through both staff-facing and digital channels. Ensuring high availability, strong performance, and resilience at scale is essential to enabling seamless and reliable customer experiences.

This is not a traditional SRE leadership role. It is a hands‑on engineering position with a robust focus on AI driven performance testing and intelligent automation at a platform level. The role is centred on building automation first capabilities, reducing manual effort, and driving predictive reliability through modern tooling and AI adoption.

Responsibilities

- Design and implement AI-driven performance testing and automation frameworks to validate scalability, resilience, and system reliability.
- Embed shift-left, automation-first testing practices into CI/CD pipelines to enable continuous, low-touch validation.
- Use AI and advanced tools to generate test scenarios, analyse performance trends, and identify bottlenecks early.
- Define, monitor, and maintain SLIs, SLOs, and performance baselines to ensure consistent reliability outcomes.
- Establish intelligent observability and AIOps practices, including proactive monitoring and self‑healing capabilities to improve issue detection and resolution.

What do I need?

- Strong experience in performance testing tools (e.g. JMeter, Gatling, k6, LoadRunner).
- Proven expertise in automation frameworks and scripting (Python, Java, or similar).




- Hands‑on experience with CI/CD, DevOps, and infrastructure automation.
- Solid understanding of SRE principles , including SLIs, SLOs, and reliability engineering practices.
- Experience with observability and monitoring tools (e.g. Splunk, Elastic Observability).
- Exposure to AI-enabled testing, AIOps, or intelligent automation tools.
- Experience in banking or regulated environments, exposure to enterprise platforms (Oracle/Siebel), knowledge of resilience practices, and an interest in AI adoption would be considered advantageous.
