Senior Network Development Engineer

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/](https://www.agsva.gov.au/). Based in Melbourne - we offer relocation support for candidates moving from other states. ## 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. As a senior engineer, you'll be the one making them - and setting the technical direction that others build upon. ## Your Opportunity What if you could build the cloud rather than just use it? As a Senior 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. Working directly with network fabrics from Top of Rack to Border/DX - managing intra-AZ, inter-AZ, and inter-Region connectivity - you'll develop both high-level and low-level designs and maintain parity with commercial AWS network standards. 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. You'll pioneer first-ever deployments in isolated environments, guide network planning cycles, and shape scaling strategies alongside our managers and program leads. If you've ever wanted your engineering decisions to matter at a global scale - and to set the direction for an entire programme - 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 - and you'll define the technical direction for how those networks grow. Your work will span the full lifecycle, from architecting
