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, I²C, 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
Assist with issue identification, debugging, and system‑level fault investigation
