• Document your work thoroughly to support validation, qualification, and certification processes.


• Collaborate with electronics, systems, and quality teams to ensure robust and compliant software delivery.


• Participate in design and code reviews, and in root cause analysis of software issues.

Who we are looking for:

You are a recent graduate or early-career engineer who is motivated to work on complex and critical embedded systems.

You are excited by the idea of contributing to real flight software in a demanding, structured development environment.

Your core qualifications, skills and mindset:

• Master’s degree in Software Engineering, Computer Science, Aerospace Engineering, or a related field.


• Solid foundation in embedded C++ programming and real-time systems.


• Knowledge of usual peripheral communication buses (i2c, SPI, UART)


• Educational or project experience in developing critical software (e.g., via coursework, internships, or academic projects).


• Familiarity with software development methodologies used for safety/mission-critical systems (e.g., V-model, ECSS, DO-178, ISO 26262).


• Comfortable reading datasheets, working with technical standards, and documenting your work clearly.
  


• Experience with versioning (Git, Gitlab) and CI tools


• A curious, meticulous, and team-oriented mindset, with a willingness to learn from senior engineers.

Bonus points if you have:

• Knowledge of modern C++ (eg.
  
  20)


• Familiarity with RTOS, STM32, automotive MCUs.


• Experience with debugging tools, simulators, or hardware-in-the-loop setups.


• Experience with Rust programming.


• Knowledge of build tools (make, cmake, Bazel, Yocto)


• Some exposure to Python or scripting tools for automation and testing.


• Experience with deterministic ethernet-based protocols


• Knowledge of field buses (1553, CANOpen)
