Electrical Engineer – High Voltage DC Power
MOMENTUS, Santa Clara, CA, USA
The Electrical Engineer will participate in both flight spacecraft system development and research projects in collaboration with science and engineering staff. This is a hands-on role that requires theoretical understanding and practical application of power electronics, high frequency switching systems, high voltage systems, circuit design, rapid prototyping, and related disciplines. The ideal candidate has 4 plus years of high voltage (kV) design and development experience and an Electrical Engineering BS, MS, or PhD. Prior experience with space applications preferred.
Specify, architect, design, and develop innovative analog and mixed-signal electronic systems, especially high voltage DC power electronics systems.
Design high power (1kW+) multi-kV power supplies with focus on safety, reliability, high efficiency, and robustness for a space environment
Work closely with external magnetics vendors on transformer design
Board bring up, testing, and debugging of power supply hardware
Produce system level, sub-system level, and block level design including circuit architecture, circuit element selection, circuit and sub-system simulations.
Develop and use mixed-signal behavioral models and behavioral simulation techniques and tools to verify sub-system and system functionality and performance.
Contribute to package selection/evaluation and validation of board and packaging design.
Create validation plans and scripts, and collect and assess validation results.
Support cross-functional teams including digital design, product engineering, test engineering, and production engineering
Create clear and thorough documentation of design and product development activities to ensure high quality designs and to support dissemination of important design information to cross-functional teams
Education & Work Experience
Minimum BS plus 4 years experience in high voltage DC power supply design,
Preferred BS, MS, or PhD in Electrical Engineering plus 8 years analog and power electronics design and verification experience
Experience in high voltage DC-DC power supply design for multi-kV systems.
Intimate knowledge of major power supply topologies buck, boost, flyback, full bridge boost, and other isolated schemes
