CDI - Embedded Software Technical Leader

By joining HyPrSpace as an Embedded Software Technical Leader, you will join our embedded software team to develop and maintain critical embedded software for our launch vehicles Baguette One and OB-1.

You will work hand-in-hand with the rest of the development teams to bring robust, certifiable flight software to life, contributing to systems that actually fly while applying rigorous engineering standards in a high-stakes aerospace environment.

Your key responsibilities :

As part of your missions, you will be entrusted with the following responsibilities:

• Actively contribute to the full development lifecycle of embedded software, from requirements definition to integration and testing
• Write and maintain C++ code for safety-critical embedded systems
• Lead the day-to-day technical activities of the software team across the full software lifecycle
• Organize, plan, and follow up on technical work
• Work with the systems team on software requirements analysis, specification, and traceability
• Contribute to and validate software design, implementation, and low-level testing (unit and integration)
• Apply and follow critical software development standards (e.g., ECSS, DO-178)
• Act as a technical referent, providing guidance and technical support to the rest of the team
• Ensure software development supports validation, qualification, and certification processes
• Collaborate with electronics, systems, and quality teams to ensure robust and compliant software delivery
• Conduct code reviews and participate in root cause analysis of software issues

Do you have experience in Software development?, Do you have a Master's degree?, * Master's degree in Software Engineering, Computer Science, Aerospace Engineering, or a related field

Experience :

• 7+ years of experience as an embedded software engineer
• Experience working on complex and critical embedded systems, preferably in structured development environments

Skills :

• Strong foundation in embedded C++ programming and real-time systems
• Knowledge of standard peripheral communication buses (I2C, SPI, UART)
• Familiarity with microcontrollers and bare-metal environments
• Experience developing critical software
• Familiarity with software development methodologies for safety- or mission-critical systems (V-model, ECSS, DO-178, ISO 26262)
• Comfortable reading datasheets, working with technical standards, and producing clear documentation
• Experience with version control and CI tools (Git, GitLab)
• Curious, meticulous, and team-oriented mindset, with a willingness to share knowledge

Bonus points if you have :

• Knowledge of modern C++ (e.g. C++20)
• Familiarity with RTOS, STM32, or automotive microcontrollers
• Experience with debugging tools, simulators, or hardware-in-the-loop setups
• Experience with Rust programming
• Knowledge of build systems (Make, CMake, Bazel, Yocto)
• Exposure to Python or scripting tools for automation and testing
• Experience with deterministic Ethernet-based protocols
• Knowledge of field buses (MIL-STD-1553, CANopen)
