• Follow and apply critical software development standards (e.g., ECSS, DO-178).
• Being a technical referent and provide technical guidance to the rest of the team
• Ensure that the development goes in the right direction to support validation, qualification, and certification processes.
• Collaborate with electronics, systems, and quality teams to ensure robust and compliant software delivery.
• Conduct code reviews, and in root cause analysis of software issues.

Who we are looking for :

You are a embedded software enginner with 7+ years of experience 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)
• Familiarity with microcontrollers and bare-metal microcontrollers.
• 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 share your knowledge.

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)
