Job summary

Blue Origin's TeraWave Spacecraft Bus team is seeking a Senior Power Electronics Engineer focused on Solar Array Regulation to own the SAR design from definition through production release. You will balance space-grade reliability with cost and manufacturability while shaping the electrical power subsystem for thousands of units.

The role demands hands-on hardware development experience with high‑voltage power electronics, EMI/EMC, and qualification campaigns per aerospace standards, with a

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a closely related field, plus 7 or more years of hands-on electronics hardware development experience.
• Demonstrated design experience with solar array regulation topologies — specifically shunt regulation, S3R, MPPT, or PPT — in a spacecraft or high-reliability power system application
• Design experience with high-voltage power electronics above 50V, including bus architecture (regulated, unregulated, or semi-regulated) and protection circuit design
• Hands-on experience leading or substantially contributing to a hardware qualification campaign per MIL-STD-1540, SMC-S-016, ECSS‑E‑ST‑10‑03, or a directly comparable standard, including test plan development and anomaly resolution
• Experience with radiation‑tolerant or radiation‑hardened design practices for space environments, including component selection and total ionizing dose (TID) analysis

Responsibilities

• Lead circuit design for the Solar Array Regulator, including S3R, PPT, and MPPT topologies for a high-voltage spacecraft power bus
• Characterize solar array electrical performance across illumination angles, temperature ranges, and eclipse/sun transition scenarios to define design margins and inform control algorithm development
• Define thermal dissipation requirements for shunt elements and collaborate with thermal engineering to validate heat rejection across all operating modes
• Derive and maintain SAR hardware requirements, interface control documents (ICDs), and design specifications in coordination with systems engineering and adjacent subsystems including thermal, structures, harness, avionics, and the solar array supplier
• Participate in FMEA/FMECA activities and drive single-point failure elimination throughout the design
• Optimize the SAR design for high-rate manufacturing, including component commonality, DFM/DFT compliance, and unit cost targets without compromising reliability or performance
• Define and transition Automated Test Equipment (ATE) from development to production, including solar array simulation capability and fault coverage validation
• Develop and execute hardware qualification plans per MIL-STD-1540, SMC-S-016, or equivalent standards, and lead anomaly investigation and resolution
• Serve as the technical authority for the SAR during vehicle integration and flight acceptance test campaigns
• Own and maintain the complete SAR design package — schematics, PCB layouts, BOMs, drawings, and analysis reports — within the PLM configuration management system
