Senior System Development Engineer, Core Networking (Relocation support available)

Gday! Youve 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 Mission - Why This Program Why Now
Youre 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 Australias 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 Australias national security community operates for the next decade. You wont be inheriting someone elses design choices. Youll be making them.

Your Opportunity
What if you could not only build the cloud but lead the engineering that makes it resilient self-healing and world-class As a Senior System Development Engineer in Core Networking youll be the driving force behind the software services and platforms that build operate monitor and assure the network within an entire region and youll set the technical direction for how those systems evolve.

This role sits at the intersection of software engineering leadership and operational excellence. Youll develop deep expertise across 170 network services built by teams spanning the globe services that cannot be directly accessed or operated by their creators within this environment. That makes you the critical bridge between innovation and execution the senior engineer who not only ensures these services run flawlessly but who architects the permanent solutions that prevent issues from ever recurring.

Youll own the dual mandate that defines this level: operational excellence today and engineering innovation for tomorrow. Youll identify patterns in operational burden and engineer them away at scale building automation and tooling that gives your team back hours days and weeks. Youll mentor fellow engineers contribute to architectural decisions that shape the programmes future and champion operational best practices that raise the bar for the entire team.

Your internal customers are your network engineer colleagues and through close collaboration you share a common goal: serve external customers and grow through learning and innovation. Youll work across multiple programming languages and frameworks lead the design of complex distributed solutions and carry full-stack responsibilities from architecture through to operational management. The breadth and depth of exposure youll gain here across AWS services technologies and complex challenges goes far beyond what a traditional service team role could offer.

This is an environment where operational problems become engineering opportunities where every recurring issue is a chance to automate at scale and where your technical leadership directly powers Australias national security capability.

Key job responsibilities
Youll own the software services and platforms that keep the AWS network running within the region and youll lead the engineering effort to continuously reinvent them to be more resilient more automated and more scalable.

Your dual mandate operational excellence today and engineering innovation for tomorrow means no two weeks look the same. Youll own the health and reliability of critical network software systems responding to operational events with the calm precision of someone who understands the architecture end-to-end. But you wont stop at firefighting. Youll identify patterns in operational burden and engineer them away building automation that transforms manual runbooks into self-healing workflows.

Your engineering work spans the full lifecycle of complex distributed systems. Youll lead the design and implementation of solutions that reduce operational toil at scale develop automation that minimises human intervention and collaborate with global service teams to enhance stability and functionality. Youll design and implement entirely new software components products and services that improve operational efficiency on behalf of your network engineer customers.

When technical issues arise youll lead the investigation diagnosing at the code or systems level performing root cause analysis implementing long-term fixes and articulating technical requirements back to service owners with clarity and precision. When incidents arise youll lead with clarity and purpose. When the dust settles youll lead the retrospective that ensures the same issue never surfaces again.

Youll mentor fellow engineers guiding them through operational deep-dives and passing on the craft of systems thinking. Youll contribute to architectural decisions that shape the programmes future champion best practices that raise the bar for the entire team and build the relationships with global service teams that ensure successful deployments and effective problem resolution.

A day in the life
Your morning begins with a health check across the services your team owns reviewing deployment pipelines scanning monitoring dashboards and confirming that overnight automated processes completed successfully. A minor anomaly catches your eye; you investigate trace it to a configuration drift in a network service and push a fix before it becomes a customer-impacting event. Thats the kind of proactive engineering that defines your approach.

By mid-morning youre deep in code. The automation framework youve been architecting is nearly ready once deployed it will eliminate a recurring operational issue that currently consumes hours of engineering time each week. Youre working across an unfamiliar codebase from a global service team reading their implementation understanding their design patterns and developing a solution that integrates cleanly with their architecture while scaling to meet the unique demands of this environment.

After lunch you join a collaboration session with a service team on the other side of the world. Theyre preparing a major deployment and need your expertise on how their service will behave in this environment. You provide detailed technical guidance flag potential issues based on your deep operational experience and agree on a deployment plan that minimises risk. You then shift to a cross-team design review where a colleague proposes a new approach to service monitoring you ask the questions that sharpen the design and volunteer to prototype a component.

Later in the afternoon you pair with a newer team member whos working through their first operational deep-dive. You guide them through the investigative process how to read the signals where to look next when to escalate passing on the craft of systems thinking that makes this team exceptional.

Before you wrap up you update the engineering backlog with a new automation opportunity you identified this morning and review a pull request from a teammate. Every day the systems get a little better because you were here.
