Principal Power Electronics - Electrical Power System Architect

Principal Power Electronics - Electrical Power System Architect

San Francisco Bay Area

We are supporting an innovative space company seeking a Senior Power Electronics / EPS Architect to own the design and maturation of a high-voltage spacecraft electrical power system, approximately 400V.

This is a technical leadership role responsible for end-to-end EPS architecture, from solar array interfaces through regulation, storage, distribution, protection, and system integration.

Key Responsibilities:

• Own the detailed architecture of a high-voltage spacecraft power system.
• Define solar array regulation including S3R or MPPT, battery charge and discharge, bus regulation, and distribution strategies.
• Lead DC-DC converter topology selection and design, including protection schemes and derating strategy.
• Address high-voltage space environment risks including plasma interaction, insulation, grounding, and compliance with relevant standards.
• Perform system-level fault analysis and FMEA, define safe-mode behaviors, and support integration with control systems and high-power payloads.
• Define and execute verification, integration, and qualification strategy through PDR, CDR, and flight readiness.

Required Experience:

• 10+ years in power electronics and spacecraft EPS design.
• Strong background in high-voltage DC systems, power conversion, and fault-tolerant distribution
• Experience delivering hardware from concept through test and qualification.
• Experience designing for radiation environments and high-reliability aerospace systems.

This is a high-impact opportunity to architect a mission-critical spacecraft power system in a fast-paced, technically rigorous environment.
