Your mission 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.

- Design, test, and validate multilayer PCBs for both high- and low-power systems using tools such as Altium, KiCad, or OrCAD - Develop and analyse 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 characterisation and validation - Prepare and maintain high-quality technical documentation, including schematics, test procedures, and verification reports - Support industrialisation 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 defence projects You are:
- Analytical and solution‑oriented, with high technical accuracy - Well‑organised and able 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 teamwhere knowledge is shared openly - Enjoy agreat work environmentthat values trust, autonomy, learning and good energy at work - Strong technical growth pathin a scaling company,where your workhas visible impactand you actively help shape both the technology and the way we work
