Job Summary

Shape the future of secure tech with us!

At Telstra, we’re more than Australia’s leading telecommunications company — we’re a tech powerhouse with a global presence in over 22 countries. We're on a mission to build a connected future where everyone can thrive, and we know that starts with our people.

We believe in creating a workplace where you feel supported, valued, and empowered — a place where your career grows with you, and where wellbeing, flexibility, and purpose are part of the everyday experience.

As a Security Architect

You will be passionate about shaping secure, forward-thinking solutions that protect millions of users and systems. In this role, you’ll be a trusted expert, helping define and embed security architecture and standards across major strategic initiatives.

Crucial : We are seeking hands‑on Security Architects with proven experience in cyber architecture assessment . This capability is highly valued because it ensures you can directly evaluate and design secure solutions rather than only oversee the process.

While leadership experience is respected, this role is best suited for professionals who have personally delivered architecture assessments and solution designs, not just led teams executing the work.

Risk assessment experience is advantageous , but your primary expertise should be in security solution assessment , as this is the core skill we’re looking for.

You will work closely with stakeholders across the business to provide security thought leadership, steer architectural decisions, and make sure our solutions are resilient, future‑ready, and aligned with Telstra’s Cyber Security Strategy.

This role suits someone who thrives in complex environments, communicates clearly, and loves bringing people together to solve tough problems.
