CesiumAstro is seeking a Staff Power Electronics Engineer to join the spacecraft payload development team. This is a hands-on technical leadership role spanning the full development lifecycle of next-generation power electronics hardware for satellites and space power systems—from architecture definition and trade studies through detailed circuit design, simulation, PCB layout, verification testing, production transition, and manufacturing support.
Key responsibilities include:
- Define electrical power system architecture and derive power subsystem requirements
- Design DC-DC power converters, motor drives, inverters, and power management/control circuits from concept to production release
- Perform detailed design of analog and power electronics circuits ranging from single converters to multi-output power supply modules
- Execute modeling and analysis including worst-case circuit analysis, stress analysis, small signal modeling, FMEA, reliability analysis, and power integrity analysis
- Develop design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans
- Lead board bring-up and design verification testing of power electronics circuits and modules
- Lead system integration, qualification campaigns, and production release of analog and power electronics designs
- Mentor younger engineers and foster knowledge sharing across the team
- Lead a small team of power electronics engineers to drive project execution
- Monitor power electronics industry trends to drive innovation and generate intellectual property
The role requires a deep technical foundation in power electronics combined with leadership capability. You will work in a dynamic, cross-functional environment on cutting-edge space and airborne communication systems.
Note: U.S. citizenship or eligible immigration status is required to comply with U.S. Government Space Technology Export Regulations.
REQUIREMENTS:
- Bachelor of Science degree or higher in Electrical Engineering (or related field) from an accredited university
- Minimum 9 years of experience designing analog and power electronics
- Experience working with electrical power systems and subsystems, including developing power architecture, performing SWAP-C trade studies, selecting power converter topologies, and defining power management and control blocks
- Proficiency in circuit simulation tools (SPICE, LTspice, etc.) and PCB design/layout tools
- Experience with analog and power electronics design for reliability, fault tolerance, and thermal management
- Programming skills to support hardware test and data processing (Python, MATLAB, etc.)
- Knowledge of MPPT for solar power applications, battery sizing and management systems, power conversion for electric propulsion, power conditioning, and power distribution units for spacecraft
- Experience designing and testing power electronics units to meet industry standards (FCC, CISPR, UL safety, ECSS, NASA, MIL standards) in automotive, industrial, space, or military markets
