Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

• 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

• 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

• Graduate degree in Electrical Engineering, Aerospace Engineering, or a related field
• 9 or more years of power electronics or power systems development experience for space or other harsh environments
• Experience with solar array simulators and I-V curve characterization equipment for qualification and production acceptance testing
• Experience in high-rate production electronics environments, including DFM/DFT optimization, production test development, and yield improvement
• Familiarity with eclipse/sun transition power management, battery charge regulation, and the downstream interactions between the SAR and power management and distribution hardware
• Experience designing and integrating high-dissipation electronics with mechanical structures for…
