Optus Network Engineering keeps Australia connected. We own the design, planning, delivery, and operation of one of Australia's largest and most critical telecommunications networks, keeping 11 million customers online every day. We support the IP infrastructure that powers mobile, broadband, and digital services across the nation, and we're looking for a Senior Platform Engineer to lead the platform engineering effort within our team.
The IP Automation & Tooling team develops and operates automation, observability, and data platforms spanning IP Core, Edge, Aggregation, and Optical domains. We own the end-to-end roadmap for transforming our IP network into an intelligent, self-healing platform. Part of that platform runs on physical infrastructure in Optus data centres. We are building an on-premises private cloud to run containerised workloads at scale, and evolving it into a multi-tenant shared service across the business. The team builds and operates this together. This role leads the platform engineering effort within it.




You will be joining a team of software engineers, network engineers, and data scientists who work alongside you. The platform is in active development, and you will lead the work of establishing the tenancy model, capacity framework, hardware lifecycle standards, and operational practices the team's workloads depend on. Platform reliability is a shared team outcome, and this role is the specialist driving it.
What You'll Do
- Lead the design and operation of a production-grade container and virtualisation platform on bare metal, covering cluster lifecycle, node management, upgrade cycles, and VM workloads via OpenShift Virtualization.
- Contribute automation in Go or Python to manage platform operations, build internal tooling, and reduce manual toil for the team.
- Establish GitOps and infrastructure-as-code practices for all platform configuration, ensuring every change is version-controlled, p
