Every day, millions of Australians connect, work, stream, and stay in touch on the Optus network. When it works seamlessly, it's easy to take for granted. But behind it is a team making thousands of decisions every day - decisions that keep people, businesses and communities connected.

Right now, Optus is focused on getting the fundamentals right - simplifying how we work, lifting standards, and building a more reliable, resilient experience for our customers.

It's not about surface-level change. It's about how we make decisions, how we work together, and how we deliver.

As a Senior Systems Engineer, you will design, develop, integrate, operate, and continuously improve the regulatory systems that support Optus' compliance obligations and reputation. This is a hands-on technical role for a coder at heart, combining full-stack engineering, data science, systems architecture, integration, installation of hardware, routing, firewalls, and operational support across the technology stack.

The role is expected to combine deep hands-on technical expertise with broad systems thinking, practical problem solving, and a strong commitment to continuous learning and operational excellence.
