About the role
- This role focuses on architecting high-voltage, high-power DC/DC conversion systems that efficiently distribute solar-generated and alternative power sources to GPU clusters and advanced computing hardware in both ground-based and orbital environments.
Responsibilities
- Design and optimize high-voltage, high-power DC/DC converter topologies for solar and alternative power sources to GPU power distribution systems in terrestrial and space-based environments (multi-kW to MW scale)
- Develop end-to-end power conversion architecture from solar/alternative power input through multi-stage distribution to GPU compute nodes, with consideration for both ground and orbital operational requirements
- Lead design of custom magnetic components including transformer and inductor designs for optimal efficiency and thermal performance
- Conduct power integrity analysis and design robust power delivery networks for high-current GPU power rails
- Own PCB design and layout for power conversion stages, ensuring signal integrity, thermal management, and manufacturability
- Perform circuit simulation, thermal analysis, and validate prototypes through bench testing and field deployment
- Collaborate with mechanical, thermal, and systems engineering teams to optimize overall power system performance
- Establish design standards, best practices, and technical roadmap for power electronics platforms
- 10+ years of professional experience in power electronics design and development
- Demonstrated expertise in DC/DC converter design, topology selection, and control strategies
Requirements
- Master's degree or Ph.D. in Power Electronics, Electrical Engineering, or related field
- Proficiency in PCB design and layout for power applications, including high-speed signal routing and thermal management
- Hands-on experience with power supply design for GPU or high-performance computing systems
- Proficiency with circuit simulation tools (SPICE, PSpice, LTspice) and thermal simulation software
- Experience with high-voltage (>48VDC) and high-power (>1kW) converter design
- Strong problem-solving skills, attention to detail, and ability to work in fast-paced environments
Nice to have
- Ph.D. in Power Electronics or equivalent advanced technical degree
- Experience with renewable energy systems integration and solar power applications
- Experience with GaN wide-bandgap semiconductor devices
- Leadership experience in managing power electronics engineering teams
- Knowledge of data center infrastructure and hyperscale computing architectures
- 10 paid holidays per calendar year
- Familiarity with GPU power delivery specifications and requirements
- Relocation assistance if applicable
