As an Electronic Hardware Engineer, you will play a key role in designing and delivering robust electronic systems for space applications. You will be part of a multidisciplinary team and involved throughout the full development lifecycle, from early design concepts to production support, ensuring high reliability and performance in demanding environments.
In this role, you will:
- Design, test, and validate multilayer PCBs for both high- and low-power systems using tools such as Altium, KiCad, or OrCAD
- Develop and analyze power electronics, including DC/DC converters, DC/AC regulators, protection systems, and thermal management strategies
- Design signal and low-power circuits for sensors, data acquisition, and embedded communication interfaces
- Build, assemble, and debug electronic prototypes, performing detailed characterization and validation
- Prepare and maintain high-quality technical documentation, including schematics, test procedures, and verification reports
- Support industrialization and production phases, ensuring smooth transition to manufacturing
- Collaborate cross-functionally with mechanical, software, and systems engineers to guarantee performance and reliability in space conditions
Your profile
We are looking for a structured and detail-oriented engineer with a strong technical foundation and a passion for solving complex challenges.
- A degree in Telecommunications Engineering, Electronics, or a related field (Master’s degree is a plus)
- At least 2 years of experience in PCB design and electronic hardware development
- Proven expertise in multilayer PCB design and EDA tools (Altium, KiCad, OrCAD)




- Solid knowledge of power electronics, including conversion topologies, component sizing, and thermal management
- Experience with low-power and signal electronics (e.g. amplifiers, ADCs/DACs, SPI, UART, CAN interfaces)
- Understanding of high- and low-power coexistence challenges (EMC, noise, plane separation)
- Experience integrating microcontrollers (STM32, ARM Cortex, or similar)
- Hands‑on experience in prototype assembly, testing, and debugging
- Strong ability to create and interpret technical documentation
It’s a plus if you also have:
- Experience working under aerospace standards (ECSS, MIL‑STD)
- Familiarity with space qualification testing (thermal vacuum, vibration, radiation, shock)
- Knowledge of space communication buses (SpaceWire, CAN, RS‑422, MIL‑STD‑1553)
- Previous experience in space or defense projects
You are:
- Analytical and solution‑oriented, with high technical accuracy
- Well‑organised and able xqbhyrx to meet project milestones
- A proactive team player with strong collaboration skills
- Comfortable working in multidisciplinary and complex engineering environments
- Clear and effective in communication and documentation
Why us?
- Work on real space hardware that will fly in orbit, not just simulations or papers
- Be part of afast‑growing European space startup shaping the future of sustainable space operations
- Hands‑on access to labs, test campaigns and cutting‑edge technology from day one
- Join ahighly collaborative, respectful and supportive team where knowledge is shared openly
- Enjoy agreat work environment that values trust, autonomy, learning and good energy at work
- Strong technical growth path in a scaling company where your work has visible impact and you actively help shape both the technology and the way we work
