Senior Power Electronics Engineer: Solar Array Regulator

Blue Origin; Denver (CO); On-site; USD 144,000 - 202,000; Full time

Job summary

Blue Origin is inviting a Senior Power Electronics Engineer to lead the Solar Array Regulator design for the TeraWave spacecraft. You will own the SAR from requirements through production release, impacting yield, cost, and reliability at constellation scale.

The role emphasizes rigorous space-grade reliability, manufacturability, and transition of ATE and testing for qualification per MIL‑STD‑1540 and related standards, across a challenging aerospace power system.

Qualifications

• Bachelor's degree in Electrical Engineering or closely related field with 7+ years of hands-on electronics hardware development experience.
• Experience with solar array regulation topologies (S3R, MPPT, PPT) in space or high-reliability power systems.
• Design of high-voltage power electronics above 50V, including bus architecture and protection circuits.
• Hands-on hardware qualification leadership per MIL‑STD‑1540, SMC‑S‑016, ECSS‑E‑ST‑10‑03, or similar standards.

Responsibilities

• Lead circuit design for the Solar Array Regulator (SAR) including high‑voltage topologies for a spacecraft power bus.
• Characterize electrical performance across illumination, temperatures, and eclipse scenarios to define margins and inform control algorithms.
• Define thermal dissipation requirements and validate heat rejection across all modes.
• Maintain SAR design package incl. schematics, PCB layouts, BOMs, drawings, and analysis in PLM.
