What you’ll do

Reliability & Resilience Engineering

• Design and automate production operational processes, including deployments, monitoring, alerting, and self-service capabilities.
• Relentlessly optimise best practice, balancing between ITIL process rigour and lean principles.
• Improve system resilience, incident recovery, observability, and performance.
• Deliver resilience and recovery testing, including chaos engineering and performance scenarios.
• Balance development speed with reliability targets through well-defined SLOs and engineering standards.

Operational Excellence & Observability

• Analyse metrics across OS, platform, and application layers to support tuning, fault diagnosis, audits, and capacity planning.
• Oversee the SDLC for reliability-focused features, including code reviews, white-box testing, and maintaining test frameworks.

Change & Incident Management

• Participate in automated change delivery, including resilience testing, verification, change control, and user communication.

• Resilience Engineering: Assess whether current patterns withstand unexpected scenarios and ensure services recover automatically.
• Stress Testing: Identify breaking points and understand system behaviour during and after failure conditions.
• Reliability Engineering: Validate that critical operations (e.g., key rotations, scaling events) occur with zero customer impact and maintain stability under load.
• Observability: Skill in proving production reliability, resilience, and performance using metrics, logs, traces, dashboards, and SLOs.

Why join us?

• Work on systems central to Australia’s financial ecosystem.
