Practical, applied understanding of aerospace control systems
Ability to develop behavioural/application-level autonomy software
Experience with version control ( Git ) within an agile team, including documentation
Strong skills with STM32 microcontrollers and associated toolchains (IDEs, debuggers, compilers)
Knowledge of low-level interfaces: CAN, SPI, IC, UART, PWM, ICU, etc.
Complementary understanding of embedded hardware
Ability to support a full testing ecosystem - from automated unit testing to flight testing
Flexibility, ownership mindset, and ability to deliver high-quality, real-world-ready software
Experience with open-source autopilot ecosystems (e.g., Betaflight, Ardupilot, PX4, MissionPlanner )
Nice to Have
Background or interest in aviation or RC model aircraft
Willingness and ability to travel, plus a driving licence and access to a vehicle
Key Responsibilities
Requirements capture and creation of technical specifications
Development of safety-critical flight-control software to exceptionally high reliability standards
Support test activities: automated unit tests, hardware-in-the-loop, field tests, and flight trials
