HYPRSPACE

POWERING AEROSPACE FUTURE WITH THE NEXTGEN PROPULSION TECHNOLOGY

At HyPrSpace, our mission is clear: to make advanced propulsion technology affordable and accessible for a wide array of applications, from civilian to defense. With our pioneering hybrid rocket engine, we're introducing a new era of aerospace capabilities—more efficient, cost-effective, safer, and sustainable.

Role overview :

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

Your profile :

Education :

• 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)

Ready to launch your career with us and help develop engines that fly ? 

Apply now and join our fast-growing team of more than 90 engineers shaping the future of launch systems. You will have a direct impact on real hardware tested on test benches—not just presentations—and you will join an agile, human-scale team with short decision-making loops and a high level of responsibility.

HyPrSpace is an equal opportunity employer, committed to building a diverse and inclusive team. Our recruitment process is based solely on the skills required for each position. If you want to make a meaningful impact, come as you are—we look forward to meeting you.

We offer a competitive compensation package, meal vouchers for each working day, and 75% coverage of public transportation costs.

We also place great importance on well-being, offering flexible working hours, a €300 annual sports allowance, and regular team events—all in the heart of the dynamic city of Bordeaux, a true crossroads of culture, vineyards, and coastal life.
