Lead DevSecOps Engineer

Streamline and secure the deployment and management of Hadrian, Praetorian’s AI-enhanced command and control system coordinating autonomous defence against drone swarms. About Praetorian Praetorian Aeronautics builds advanced autonomous aerial systems designed to protect and defend against the rapidly evolving threat of drone warfare. Headquartered in Adelaide, we are developing an integrated ecosystem of counter-autonomy systems including: Arrow – an autonomous, high-speed, low-cost, VTOL interceptor for neutralisation of multiple UxS threat-types beyond visual range Dagger – a new class of modular, low-cost, autonomous, high-speed interceptor for long-range, high-altitude kinetic neutralisation of UxS targets Hadrian – an AI-enhanced command and control system enabling operators to deploy interceptors at scale Venator – a long-endurance autonomous mothership UAS capable of deploying interceptors and extending operational reach Together, these systems enable defence operators to detect, assess, and defeat autonomous threats while maintaining situational dominance in contested environments. Why This Role Matters Offensive drone capability and their collective use in swarms represent one of the fastest-growing threats in modern warfare. Hadrian provides the command and control layer that allows operators to understand swarm behaviour, plan responses, and coordinate autonomous interceptors. As a DevOps Engineer on Hadrian, you’ll help build and secure the platform that turns advanced autonomy research into operational defence capability and ensure capability updates are readily deployable in an assured and cyber-aware manner.
