You will work across customer-facing platforms to improve system availability, automate operational processes, enhance observability, support incident management, and leverage AI technologies to reduce operational toil and improve engineering efficiency.
Key Responsibilities
- Improve service reliability, availability and operational resilience through robust monitoring, resilience testing, disaster recovery planning, and management of SLIs, SLOs and error budgets.
- Design and enhance observability capabilities including monitoring, alerting, dashboards, synthetic monitoring, automated health checks, and visibility across customer journeys and cloud environments.
- Develop automation, self-healing capabilities, operational tooling, Infrastructure as Code and CI/CD practices to reduce manual effort and improve platform reliability.
- Participate in major incident response, service restoration, root cause analysis and continuous improvement initiatives to minimise customer impact and improve recovery times.
- Design and implement AI-driven operational solutions, utilise LLMs for incident triage and remediation, and drive adoption of GitHub Copilot and AI-assisted engineering practices.

- Demonstrated experience in Site Reliability Engineering (SRE), Production Engineering, DevOps or Platform Engineering, with a strong understanding of distributed systems, cloud technologies and modern application architectures.
- Hands-on experience with AWS and/or Azure, Kubernetes, container platforms, CI/CD pipelines and Infrastructure as Code (IaC) practices.
- Strong expertise in observability and monitoring using tools such as Splunk, Dynatrace, Grafana, Prometheus, OpenTelemetry or similar enterprise monitoring platforms.
- Proficiency in programming and scripting languages including Python, Java, Go, PowerShell or equivalent technologies to support automation and platform engineering initiatives.
- Experience using AI-assisted development tools such as GitHub Copilot, Microsoft Copilot, Claude or ChatGPT, with knowledge of LLMs, AI agents, agentic workflows, prompt engineering and responsible AI practices.
- Strong operational excellence capability across incident management, problem management, change management, root cause analysis, performance engineering, capacity planning, disaster recovery testing and operational readiness.
- Banking or financial services experience is highly regarded, particularly supporting mission-critical digital banking or payment platforms, with knowledge of APRA CPS 230 Operational Resilience requirements and experience developing AI agents, AIOps solutions or autonomous operational capabilities.
