Linux Product Team Lead (AU)

About the role

We are looking for a Linux Product Team Lead to lead and grow the C2 Linux Product Team, owning the Linux platform that underpins the DroneSentry-C2 ecosystem. This is a hands-on technical leadership role focused on Linux platform engineering, reliability, security, automation and observability across development, production and deployed customer environments.

Initially focused on the Linux platforms supporting the DroneSentry-C2 ecosystem, the role will progressively expand to establish platform standards, Linux capabilities and engineering practices across DroneShield's broader portfolio of internal and customer-facing products. You will lead the Linux Product Team and work closely with Software, AI, Security, Infrastructure and Product teams to deliver secure, scalable and highly reliable Linux platforms and services.

Key areas of ownership include:

• DroneSentry-C2 and ruggedised field hardware
• Development and maintenance of secure Linux SOEs
• Testing Linux compatibility and performance across server and edge platforms
• Infrastructure supporting Linux device manufacturing
• Software supply chain security
• Secure remote access platforms
• Platform observability, monitoring and reliability
• Providing L3 support for OS and system-level issues across production and deployed assets

If you're interested in solving hard problems, building platforms that need to withstand the attention of nation-state adversaries, and working alongside red and blue teams to continuously test, break and improve our systems, this is the role for you. You'll help build the platforms that power real-world defence capabilities, where security, reliability and operational excellence aren't nice-to-haves, they're mission-critical.

This role reports to the Director, AI Systems & Platforms.
