Hardware Electronics Engineer – High Voltage & Power Electronics

Your mission

We are looking for a Power Electronics / High Voltage Hardware Engineer capable of designing and validating electronic systems that generate, regulate and distribute power for space propulsion applications.

The ideal candidate has practical experience developing DC/DC converters, high-voltage electronics, and power conversion architectures, and is comfortable taking designs from concept through laboratory validation.

You will work closely with RF, Plasma, Systems and Mechanical Engineers to develop the next generation of electric propulsion hardware.

Key Responsibilities

• Design, develop and validate power electronics hardware for space propulsion systems.
• Develop DC/DC converters, high-voltage power stages and power distribution architectures.
• Support component selection, PCB design reviews, hardware debugging and thermal management solutions.
• Define and execute laboratory testing, performance analysis and system validation activities.
• Contribute to the development of future Power Processing Units (PPUs) and collaborate with multidisciplinary engineering teams.

Your profile

• Bachelor's or Master's Degree in Electronic Engineering, Electrical Engineering, Telecommunications Engineering, Power Electronics or a related field.
• 3+ years of experience in power electronics development.

Essential Technical Skills

• Experience designing DC/DC converters and switched-mode power supplies (SMPS).
• Understanding of voltage conversion, control loops and converter stability.

• Experience with high-voltage systems and circuits operating above 300V.
• Knowledge of insulation, protection strategies and HV safety requirements.

• Schematic capture, PCB design and analog circuit development.
• Experience selecting power components such as MOSFETs, IGBTs, GaN or SiC devices.

• Hardware bring-up, debugging and root cause analysis.
• Experience using laboratory instrumentation and validating power electronics performance.
