Your strong grasp of emerging technologies and real‑world attack vectors will position you to deliver secure, user‑focused solutions that empower innovation while safeguarding Telstra’s digital assets.

• Security control design and implementation.
• Demonstrated success in driving technical and security leadership.
• Zero Trust architecture (cloud and on‑premises).
• Endpoint and identity protection (e.g., CrowdStrike, BeyondTrust, Lookout).
• Privileged access and secrets management (e.g., CyberArk, LastPass).
• Data and API protection (e.g., Cequence, Netskope, Microsoft Purview).
• Work‑life integration – flexibility around where and when you work.
• 16 weeks paid parental leave for primary and secondary carers.
• Laptop/Device allowance renewed every 2 years.
• Purchased Annual Leave scheme.
