Network Development Engineer, Network Core (Relocation support available)

Description 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. More information regarding security clearances can be found at https://www.agsva.gov.au/. 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. You won't be inheriting someone else's design choices. You'll be making them. Your Opportunity What if you could build the cloud rather than just use it? As a Network Development Engineer, you'll be at the heart of the infrastructure that powers the world's largest cloud computing platform — not configuring services on top of it, but engineering the very fabric that makes it all possible. This is your chance to work at a scale few engineers ever experience. You'll design, build, and operate next-generation network infrastructure where every decision you make ripples across millions of customers worldwide. You'll collaborate with some of the most talented engineers in the industry, sharing ideas and pushing boundaries in an inclusive culture that doesn't just welcome bold thinking — it demands it. Here, your passion for learning meets limitless opportunity. You'll work with leading tools and technologies that haven't reached the mainstream yet, solving problems that require permanent, sustainable, and scalable solutions. If you've ever wanted your engineering decisions to matter at a global scale, this is where that happens. Benefits - Learning & development - AWS training and certification support, access to internal learning platforms. - Health, income protection and life cover - Amazon subsidises private health insurance premiums, and group salary continuance and life insurance are included at no cost to you - Military differential pay launching in Australia - Australian employees taking defence reserve leave may receive up to 52 weeks of military differential pay to help cover the difference in pay while serving - Employee Assistance Program - Free, confidential support 24 hours a day, 7 days a week for you and your family - mental health, financial coaching, legal questions, and everyday life events. - Family-building benefit - Access to Maven for fertility treatment, adoption support, surrogacy, and parenting coaching - Amazon Extras & employee discount - cashback and discounts across hundreds of retail, fitness, travel, and lifestyle partners. Key job responsibilities You'll own the engineering, implementation, and evolution of networks that operate at a scale most engineers only read about. Your work will span the full lifecycle — from deploying next-generation network infrastructure to ensuring it runs with the reliability and performance that millions of customers depend on every single day. You'll lead network projects that shape how our infrastructure grows and adapts: scaling initiatives, technology refreshes, deployment implementations, and optimisation efforts that push the boundaries of what's possible. When customer-impacting events occur, you'll be the engineer who responds decisively — troubleshooting with precision, resolving with speed, and then building the automation that ensures the same issue never surfaces again. Your analytical mindset will drive you to interrogate the network using advanced tools and metrics, ensuring every component operates correctly, safely, and securely. When complex technical issues arise, you'll investigate them scientifically and thoroughly, tracing root causes and implementing fixes that are permanent rather than temporary. But you won't just maintain what exists — you'll invent what comes next. You'll develop automation and mechanisms that eliminate manual operations, design sustainable and repeatable processes, and identify bottlenecks before they become problems. You'll evaluate emerging networking technologies and develop strategies for safely integrating them into our environment. Every solution you deliver will embody the principle of choosing the best approach over the quickest fix — because at this scale, shortcuts don't exist. A day in the life Your morning begins with a pulse check on the network — reviewing metrics dashboards, assessing overnight alerts, and confirming that the infrastructure you've engineered is performing as designed. You notice a subtle anomaly in traffic patterns and dig deeper, using advanced diagnostic tools to trace the signal through layers of network fabric. By mid-morning, you're collaborating with your team on a scaling project that will expand capacity across a critical network segment. The whiteboard fills with architecture diagrams as you debate approaches, challenge assumptions, and converge on a solution that's both elegant and sustainable. Your colleagues bring diverse perspectives, and the energy in the room reflects a team that genuinely enjoys solving hard problems together. After lunch, you shift focus to automation. A recurring operational task has been consuming engineering hours, and you've designed a mechanism to eliminate it entirely. You're refining the code, testing edge cases, and documenting the approach so others can build upon your work. There's deep satisfaction in knowing this automation will free your team to focus on higher-value engineering. Late afternoon brings a customer-impacting event. You move swiftly into troubleshooting mode — methodically isolating the issue, applying your deep networking knowledge, and coordinating with team members to restore service. Once resolved, you capture the root cause and begin designing the preventive measure that ensures it won't recur. You end the day knowing that your work directly enables Australia's national security community to operate with confidence — and that tomorrow will bring an entirely new set of challenges worthy of your talent. About the team The Network Development team drives engineering, implementation, scalability, operations, reliability, and sustainability for all of the network fabrics that underpin the software services and platforms used within an AWS region.
