Location: Vigo, Galicia, Spain (onsite / hybrid)

Industry: Space Systems | Satellite Engineering | Power Electronics

About the Role

Our client, a leading European space technology company, is seeking an experienced Power Electronics Design Engineer to join their growing satellite engineering division. You will play a key role in the design, development, and qualification of advanced power subsystems for spacecraft platforms, working closely with multidisciplinary teams across systems, electrical, and mechanical engineering.

Key Responsibilities

• Design and develop DC-DC converters, power distribution units (PDUs), and battery management systems for satellite applications.
• Perform schematic design, component selection, circuit simulation, and PCB layout reviews for space-grade power systems.
• Conduct worst-case, thermal, and radiation analysis to ensure compliance with ESA and ECSS standards.
• Support hardware testing, validation, and environmental qualification (thermal vacuum, vibration, EMC).
• Collaborate with systems engineers to define power budgets, interface requirements, and redundancy strategies.
• Generate and maintain technical documentation, test procedures, and design reports throughout the development lifecycle.
• Provide technical support during integration and launch campaign phases.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics, or related field.
• 3+ years of experience in power electronics design—preferably within the aerospace, defense, or high-reliability sectors.
• Strong understanding of DC/DC converter topologies, power conditioning, and control loop design.
• Experience with SPICE simulation tools (LTspice, PLECS, etc.) and Altium Designer or similar CAD tools.
• Familiarity with ECSS or ESA standards, space-qualified components, and radiation effects mitigation techniques.
• Proficiency in English (written and spoken); Spanish is an advantage.

Desirable Skills

• Experience with FPGA-controlled power systems or digital power regulation.
• Knowledge of battery systems, solar array regulation, or EPS architectures for satellites.
• Hands-on experience with hardware testing, debugging, and validation in laboratory environments.

What’s on Offer

• Competitive salary and relocation package (if applicable).
• Opportunity to work on cutting-edge European satellite missions.
• Supportive, international engineering environment with career development pathways.
