Take a proven drone prototype and transform it into production-ready technology that's revolutionising critical infrastructure. You'll architect and develop the core software that directly controls autonomous drones, with an incredibly short feedback cycle - see your code flying in real-world operations within days.

Work alongside a talented team where technical discussions thrive and your individual growth is prioritised. You'll have real ownership over projects with tangible outcomes - watching drones execute missions powered by software you've built and refined.

You'll be involved across the entire drone software stack, from low-level flight control systems to 3D pilot applications and simulation tools. Your architectural decisions will directly influence how safely and effectively our drones operate in demanding environments.

What you'll do

Architect and develop our C++20 drone software stack, making key technical decisions as we transition from prototype to global production deployment. You'll balance urgent operational fixes with long-term system improvements to ensure mission-critical reliability.

Build and optimise safety-critical flight control software, 3D rendering systems for pilot applications, and simulation tools that support real-world drone operations. You'll work on everything from low-level drone control to post-flight data analysis.

Collaborate with Integration and Operations teams to rapidly test and deploy new features, solving operational challenges and improving system robustness. You'll also share best practices and contribute to technical discussions that drive the team's expertise.
