Systems Engineer in Sydney

G'day! You've found an opportunity that could define your next chapter. Applicants must be Australian citizens and hold or be eligible to obtain an Australian Government Security Clearance with the ability to successfully complete an Organisational Suitability Assessment.

The Mission - Why This Program, Why Now? 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.

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.

Key job responsibilities:

• 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, Private DNS configurations, Geo DNS routing, and failover architectures.
• You'll write production-quality code daily, building automation frameworks, developing monitoring systems, or creating tooling that multiplies your team's effectiveness.
• Integration is where you'll truly shine, connecting Route 53 with the broader AWS ecosystem and collaborating across teams.
• Operational excellence runs through everything you do, building and refining runbooks, leading incident response, and conducting root-cause analyses.
• You'll mentor teammates, share knowledge generously, and help build a culture where engineering excellence is the baseline.

A day in the life: Your day starts with purpose. Over your morning coffee, you review overnight metrics dashboards. Mid-morning finds you in a design session with your team, sketching out a new Geo DNS architecture. After lunch, you're in flow state — writing automation code that will reduce DNS change propagation time. The afternoon brings a cross-team integration session where you explain complex DNS concepts clearly.
