Qualifications
Bachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university.
Minimum of 9 years of experience designing analog and power electronics
Experience working with electrical power systems and subsystems, including developing power architecture and power requirements, performing trade studies for size, weight, power, and cost optimization (SWAP-C), selecting power converter topologies, and defining power management and control blocks
Experience with modeling and control of DC-DC converters and power stage design of different isolated and non-isolated DC-DC power converters (e.g. discrete linear regulators, Buck, Boost, Buck-boost, Flyback, Forward, Half-bridge, Full bridge, and Resonant converters)
Experience with power stage design for inverters and motor drives
Experience designing custom signal and power magnetics, and power filters for low noise and electromagnetic compatibility (EMC)
Experience developing design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans
Experience performing worst-case circuit analysis (WCA), stress analysis, failure modes and effects analysis (FMEA), and reliability analysis for power supplies
Extensive hands-on experience with testing and troubleshooting electronics and power converters using laboratory instruments such as oscilloscopes, impedance analyzers, spectrum analyzers, electronic loads, and signal generators
Experience with electronics schematic capture and printed circuit board (PCB) layout tools such as Altium, OrCAD, Allegro or Xpedition
Experience with analysis and simulation tools such as SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, MathCAD, ANSYS Q3D and SiWave, or HyperLynx
Excellent written and verbal communication skills
Experience
Master of Science or PhD in Electrical Engineering with research focus in power electronics
Experience designing high-reliability analog and power electronics for space or defense applications
Knowledge of space radiation environments and radiation effects in electronics
Experience in power electronics applications utilizing GaN or SiC wide bandgap power semiconductor devices
Experience running board-level power integrity simulation using tools such as Ansys SiWave, or HyperLynx
Experience with soft switching and resonant power converter topologies (e.g. LLC, CLLC, series resonant, phase shifted full bridge, dual active bridge, etc.)
Experience with modeling and control of inverters and motor drives
Experience with advanced control schemes for DC-DC power converters (e.g. voltage mode with feedforward control, constant on-time control, V2 constant on-time control, phase shift modulation, average current mode control)
Experience with isolation and grounding, failure mode effects analysis and fault tolerant design, and thermal management of power electronics
Programming skills to support hardware test and data processing (Python, MATLAB, etc.)
Experience with maximum power point tracking (MPPT) for solar power applications, battery sizing and battery management systems, power conversion for electric propulsion systems, power conditioning, power management, and power distribution units for spacecraft technology
Experience designing and testing power electronics units to meet industry standards and requirements in the automotive, industrial, space or military markets (e.g., FCC, CISPR, UL safety, ECSS, NASA, MIL standards)
