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
