We are looking for a Sr. Electrical Engineer - Power Electronics to take ownership of the spacecraft’s power systems, including solar panels, batteries, battery control modules, and the power distribution system. In this role, you will be responsible for designing, developing, and testing the electrical systems that generate, store, and distribute power throughout the satellite. You will also own the development and maintenance of the power budget, and ensure compliance with EMI/EMC design standards.

This is a hands-on, cross-disciplinary role where you will work closely with experienced engineers across electrical, systems, mechanical, and software teams. It is a unique opportunity to build a critical subsystem of a cutting-edge space technology platform.

What You’ll Do:

• Design and develop the end-to-end solution of the satellite’s power subsystem, including solar arrays, batteries, battery control modules, and power distribution hardware

• Develop and manage the spacecraft power budget across all mission phases

• Design and validate battery management systems, including protection, charging, and state-of-health monitoring

• Support integration of power systems with other spacecraft subsystems

• Ensure designs are compliant with EMI/EMC standards and spaceflight reliability requirements

• Conduct schematic capture, PCB layout reviews, and component selection for power electronics

• Participate in electrical testing and validation at the unit, subsystem, and system levels

• Support hardware bring-up, debugging, and performance tuning in lab and flight environments

Requirements

• B.S. in Electrical Engineering or a related field

• Understanding of solar panel and battery technologies, especially for aerospace or high-reliability applications

• Experience with PCB design, including power electronics layout and high-current routing

• Familiarity with battery management systems, power conversion, and safety circuitry

• Basic knowledge of EMI/EMC considerations and applicable aerospace standards (e.g., MIL-STD-461)

• Hands-on experience with electrical testing tools (e.g., oscilloscopes, power analyzers, logic analyzers)

• Strong analytical and problem-solving skills, with attention to detail in design and documentation

• A collaborative, team-oriented mindset and the ability to communicate effectively

• Bonus: Experience with electronics design for space and spacecraft power systems

• Work onsite in Burlingame, CA. You’ll work closely with the satellite team in a dynamic, fast-paced environment.
