Front End Software Engineer (egui / ImGui)

About the role

Praetorian Aeronautics builds autonomous counter-drone systems for defence operators, headquartered in Adelaide with offices in Melbourne and Darwin. Its Hadrian battle-management system lets a single operator detect, decide and defeat complex threats, and the role is to build its operator interface in Rust using egui, turning real-time sensor, track and system data into fast, readable displays on native, web and ruggedised hardware.

Key responsibilities

• Build high-performance operator interfaces in Rust with egui (and Bevy where needed) for native and WebAssembly targets
• Render real-time tracks, maps, telemetry and system status without compromising responsiveness
• Turn operator workflows into simple, intuitive interactions based on user and trial feedback
• Integrate with backend services, data links and third-party C2 systems
• Support field trials to see the work in operational use

Required profile

• Experience building with an immediate-mode GUI framework: ideally egui in Rust, or Dear ImGui in C++ with a willingness to work in Rust
• Strong understanding of performance in real-time, data-heavy interfaces
• Experience shipping cross-platform applications, ideally including WebAssembly
• Good UX instincts and comfort in a fast-moving startup
• Nice to have: Bevy, mapping/geospatial or 3D visualisation (walkers, wgpu), defence/C2/TAK or MAVLink exposure, robotics/drones or safety-critical systems background
• Full rights to work in Australia, with PR and a pathway to citizenship within 12 months, or citizenship of a Five Eyes nation; no security clearance required now

What we offer

• Hybrid work and flexible start and finish times
• Direct ownership of your work, with code in operators' hands at trials
• Access to the Employee Share Option Plan (ESOP)
• A defined engineering career framework
• Work alongside specialists in flight sciences, electronics, autonomy and test, with direct access to leadership
