You’re joining at the defining moment of one of the most significant technology programmes Australia has ever undertaken. This programme will build and operate the dedicated cloud giving Australia’s national security community and its allies the capability to see more, share more, innovate and act faster than ever before.

The architectural decisions being made now - how we structure networking, implement security controls, and automate at scale - will shape how Australia’s national security community operates for the next decade. You won’t be inheriting someone else’s design choices. You’ll be making them.

Your Opportunity Picture yourself at the intersection of sovereign cloud innovation and one of the world’s most critical DNS infrastructures. As a Systems Engineer within our Region Services team, you’ll be redefining how AWS designs, builds, and operates cloud regions - enabling new infrastructure and services offerings that serve customers across every industry, from ambitious start-ups to the public sector organisations safeguarding our nation.

Route 53 isn’t just another DNS service - it’s the nervous system of the internet operating across 50+ global locations with a 100% availability SLA. You’ll be engineering latency-based routing, Private DNS architectures, Geo DNS solutions, and failover mechanisms that millions depend on without ever knowing your name. The distributed systems you’ll build here are among the largest and most complex on the planet, and the challenges waiting for you are the kind that make exceptional engineers come alive.

Whether you choose Melbourne or Sydney as your home base, you’ll join a team of adaptable, passionate engineers who thrive on complexity and refuse to accept “good enough.” Your technical expertise and development abilities will drive innovation that echoes far beyond a single service - you’ll be shaping how Australia’s sovereign cloud capability operates for a generation., You’ll own the full engineering lifecycle of Route 53’s DNS infrastructure within this programme - and that means your fingerprints will be on everything from initial architecture through to operational excellence at scale.

Your core mission is designing and implementing DNS solutions that leverage Route 53’s advanced capabilities: latency-based routing that shaves milliseconds off critical queries, Private DNS configurations that enable secure service discovery, Geo DNS routing that directs traffic with surgical precision, and failover architectures that ensure zero downtime when it matters most.

You’ll write production-quality code daily. Whether it’s building automation frameworks that accelerate change propagation, developing monitoring systems that surface anomalies before they become incidents, or creating tooling that multiplies your team’s effectiveness - your development skills are as essential as your systems expertise.

Integration is where you’ll truly shine. You’ll connect Route 53 with the broader AWS ecosystem, collaborating across teams to ensure seamless interoperability between services. You’ll participate in architectural reviews, challenge assumptions constructively, and propose solutions that balance innovation with the reliability this programme demands.

Operational excellence runs through everything you do. You’ll build and refine runbooks, lead incident response with calm expertise, conduct root-cause analyses that prevent recurrence, and continuously raise the bar for system reliability. You’ll mentor teammates, share knowledge generously, and help build a culture where engineering excellence is the baseline, not the aspiration.

A day in the life Your day starts with purpose. Over your morning coffee, you review overnight metrics dashboards - not out of anxiety, but curiosity. You notice a subtle shift in query patterns across one routing policy and make a mental note to investigate. This is the kind of signal that separates good engineers from great ones, and you’ve trained yourself to see it.

Mid-morning finds you in a design session with your team, sketching out a new Geo DNS architecture on a whiteboard. The Region Services context adds fascinating constraints - you’re not just solving for performance, you’re solving for sovereignty, security, and scale simultaneously. A colleague challenges your approach, you refine it together, and the final design is stronger than either of you could have produced alone.

After lunch, you’re in flow state - writing automation code that will reduce DNS change propagation time within the programme’s environment. Every function is clean, every edge case handled, every test passing green. You push your changes through the CI/CD pipeline you helped build, watching them propagate with the confidence that comes from engineering done right.

The afternoon brings a cross-team integration session. Another team needs Route 53 health checks woven into their monitoring framework, and you’re the expert who makes it happen. You explain complex DNS concepts clearly, draw architecture diagrams that illuminate rather than confuse, and leave the room knowing the broader system is more resilient because of your contribution.

As you wrap up from your Melbourne or Sydney office, you review a teammate’s pull request with the care and thoughtfulness you’d want applied to your own code. Today, like every day here, your work made Australia’s sovereign cloud infrastructure more capable, more reliable, and more ready for whatever comes next.
