Job description

Singapore Telecommunications – Macquarie Park NSW

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 Solutions Architect, you will collaborate with cross-functional teams across the organization, including engineering, operations, security, and business stakeholders, to develop and implement high-level and low-level designs that align with our strategic objectives. You will also play a crucial role in driving technology innovation, lifecycle management, and governance to ensure our network infrastructure remains resilient, scalable, and future proof.

This role requires a blend of technical expertise in muti-technologies areas, leadership, and strategic thinking to design, implement, and manage robust network solutions that support an organization's objectives. The role will report to the Director – IP Core and Access Engineering/Networks.
