What you will do

• Define electrical power system architectures, derive subsystem requirements, and perform trade studies for next-generation spacecraft payloads.
• Design DC-DC converters, power conditioning, power management, control circuits, and multi-output power supply modules from concept through production release.
• Model and analyze analog and power electronics designs, including worst-case, stress, reliability, power integrity, and failure modes and effects analyses.
• Develop verification, compliance, integration, qualification, and production acceptance test plans.
• Lead board bring-up, design verification, system integration, qualification campaigns, and production transition.
• Mentor engineers, research industry trends, support manufacturing, and generate intellectual property.

Requirements

• Bachelor of Science degree or higher in Electrical Engineering or a related field from an accredited university.
• At least 5 years of experience designing analog and power electronics.
• Experience with electrical power systems and subsystems, including power architecture, power requirements, SWAP-C trade studies, converter topology selection, and power management and control blocks.
• Experience designing common DC-DC converter topologies, including discrete linear regulators, Buck, Boost, Buck-boost, Flyback, and Forward converters.
• Experience modeling and characterizing voltage-mode and peak-current-mode control for DC-DC converters, including control-loop and impedance characterization in the laboratory.
• Knowledge of control theory and power electronics stability, as well as power filters for low-noise outputs and power-line EMC.
• Experience developing design verification, requirement compliance, system integration, qualification, and production acceptance test plans.
• Experience performing worst-case circuit, stress, FMEA, and reliability analyses for power supplies.
• Extensive hands-on experience testing and troubleshooting electronics and power converters with oscilloscopes, impedance analyzers, spectrum analyzers, electronic loads, and signal generators.
