Descripción de la vacante

Cowboy Space Corp. is seeking a Principal Power Engineer to lead the design of high‑voltage, high‑power DC/DC conversion systems for terrestrial and orbital data‑center infrastructure.

You will architect end‑to‑end power delivery from solar and other inputs through multi‑stage distribution to GPU compute nodes, drive system architecture, optimize efficiency, and mentor the power‑electronics team.

Formación

• Master's degree or Ph.D. in Power Electronics, Electrical Engineering, or related field.
• 10+ years of professional experience in power electronics design and development.
• Demonstrated expertise in DC/DC converter design, topology selection, and control strategies.
• Strong background in magnetic component design including transformer and inductor design, material selection, and optimization.
• Proficiency in PCB design and layout for power applications, including high‑speed signal routing and thermal management.
• Deep expertise in power integrity analysis, including PDN design, component optimization, and control theory.
• Hands‑on experience with power supply design for GPU or high‑performance computing systems.

Responsabilidades

• 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
• Specify and integrate GPU power supply modules, working closely with GPU supplier on power delivery requirements and validation
• 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
• Mentor junior engineers and contribute to continuous technical advancement of the power systems team
