The AWS Region Services team combines AWS global cloud leadership with Australian security expertise to deliver highly secure, scalable environments for sensitive workloads. We’re creating innovative ways to use cloud computing, artificial intelligence, and machine learning while maintaining the highest standards of security and operational excellence. The Engineering organisation within Region Services is structured across core capability pillars: Compute & Machine Learning, Security Identity & Compliance, Storage & Databases, and a growing capability domain. Collectively these pillars encompass a team of varying technical skillsets, including Engineers; Technical Program Managers and Subject Matter Experts, organised into focused sub-teams. This is an opportunity to make a lasting impact on Australia’s digital future. You’ll work with AWS services, implement innovative solutions, and help customers succeed in their most important missions. We’re committed to helping our builders grow through continuous learning, mentoring, and collaboration with industry experts. Are you ready to build the future of secure cloud computing in Australia? Key job responsibilities - Define and/or refine system requirements, participate in the development and delivery of operability-related features such as system health monitoring, diagnostics, repair, and other self-healing automation - Develop or further existing application and system management tools and processes that reduce manual efforts and increase overall efficiency - Adapt and improve operations management systems and processes to accommodate rapid and increasing growth in systems and traffic - Participate in the design and execution of production acceptance tests and new hardware evaluations - Monitor the health of the fleet, automating system health, maintenance tasks, and reporting systems as needed - Participate in “on-call” rotations to resolve incidents occurring out-of-hours.

The metrics tell the story: fourteen automated remediations overnight, zero pages to the on-call engineer. You refine a detection threshold that's been slightly too sensitive, commit the change, and watch the next cycle run cleanly. By mid-morning, you're in a requirements session with the team. A new service is approaching production readiness, and you're defining the operability features it needs: what health signals to emit, what diagnostic paths to expose, what self-repair mechanisms to implement. You push for completeness — because the time to think about operability is now, not after the first incident. After lunch, you're deep in code. An existing management tool needs to handle three times its current throughput as the fleet scales into its next growth phase. You redesign the data ingestion layer, implement parallel processing, and write load tests that validate performance at projected scale. The refactored system handles the load with headroom to spare. Later, you join a hardware evaluation session. New server variants have arrived, and you're helping design acceptance tests that will stress them under realistic production conditions. Your test harness is automated and repeatable — results flow directly into a report that the team can act on immediately. Before wrapping up, you investigate a
