At nbn, senior security engineers help shape the future of Australia by protecting critical national infrastructure. The role focuses on the integrity and resilience of the network security platforms that support the country’s broadband backbone.
You will work within agile DevSecOps pods alongside over 500 engineers, delivering secure and scalable solutions for both enterprise and active network domains. The position combines hands‑on technical delivery with operational support, and you will champion best‑in‑class security practices throughout the organisation.
Successful candidates are experienced security professionals with deep knowledge of network protection—proxies, IDS/IPS, VPNs and secure architecture—and are comfortable applying Agile and DevSecOps methods. Strong leadership, collaboration and a proactive, empathetic mindset are essential for guiding teams and removing obstacles.
This is a permanent full‑time role open to applicants with full Australian working rights. Interested candidates should submit a resume (no cover letter required) by the closing date, and can contact the recruitment accessibility line for any adjustment needs.
nbn is committed to an inclusive, flexible workplace that values diversity and provides a supportive environment for all staff.
