• Participate in component selection in accordance with space standards (ECSS, MIL-STD, etc.)
• Collaborate in HW‑SW system integration with other departments (software, systems, integration and testing)
• Prepare technical documentation in compliance with aerospace standards
• Support environmental test campaigns (EMC, vibration, thermal‑vacuum, etc.)
• Collaborate with suppliers for the manufacturing and assembly of electronic boards
• Participate in design reviews (PDR, CDR) with clients or agencies (ESA, NASA, etc.)

University degree in Electronic Engineering, Telecommunications Engineering, Aerospace Engineering or similar

A minimum of 8 years in electronic hardware design, preferably in high‑reliability environments (aerospace, defense, automotive)

Experience in multilayer PCB design, high‑speed design, and environments with thermal or electromagnetic constraints

• Knowledge of ECSS, DO-254, IPC

• Analytical and complex problem‑solving skills
• Teamwork in multidisciplinary environments
• Proactivity, autonomy and results orientation
