Job Summary

Job Description

Who We Are

We're an iconic Aussie brand with a global footprint. Our purpose is to build a connected future so everyone can thrive. We're all about providing the best experience and delivering the best tech on the best network.

This includes making Telstra the place you want to work. For you, that means having a career that grows with you and working with a team powered by human connection that prioritizes wellbeing and choice.

About the Role

Telstra continues to strengthen network‑level prevention capabilities in response to rising customer harm, expanding network scale, and increased regulatory scrutiny. Within Converged Core Engineering, protection is no longer a peripheral activity; it is a business‑critical network capability that must operate at scale, by default, and with high confidence. This role sits at the intersection of network engineering, software platforms, cloud infrastructure, and commercial decision‑making. It owns the Packet Core Multi Mediation (PMM), Telstra Multi Mediation (TMM), Equipment Identity Register (EIR) and Calltrack capabilities and applications supporting complex voice, scam and threat problems into scalable, reliable and defensible network capabilities embedded directly within Telstra’s core and wireless networks. The role is designed as the successor to the Numbat PO / Scam Lead / CTL role, with clear headroom to grow into broader domain or portfolio leadership over time. 

Focus of the Role

The Product Owner – Core Network Enablement owns the end‑to‑end product outcomes for network‑embedded (PMM, TMM, EIR and Call track) operations, fraud and scam prevention and strategic capabilities across core and wireless environments. The role ensures that protection capabilities are engineered into the network, not layered on top, balancing customer protection, network resilience, regulatory obligations and commercial outcomes. The Product Owner acts as the single point of accountability for vision, prioritisation, delivery and operational outcomes, partnering closely with network engineering, cyber security, data, legal, compliance and commercial stakeholders.
