In this position, you will contribute across the entire development lifecycle of next-generation power electronics hardware for military and commercial power systems-from leading the definition of power system architectures and trade studies to detailed circuit design, simulation, printed circuit board (PCB) layout, verification and integration testing, production transition, and manufacturing support.\nJOB DUTIES AND RESPONSIBILITIES\nLead the development of power system architectures and derive power subsystem requirements.\nDesign DC-DC power converters, power supplies, and power distribution systems ranging from a few watts to more than 20 kW of power in the 0.8 V to 400 V range. \nDesign single-phase and three-phase AC-DC power supplies and power distribution systems ranging from a few kilowatts to more than 20 kW. \nPerform comprehensive analysis of AC-DC and DC-DC power supplies including worst-case circuit analysis (WCA), stress analysis, small signal modeling analysis, failure modes and effects analysis (FMEA), reliability analysis, and power integrity analysis. \nDevelop design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans for power converters and power supplies. \nLead board bring-up and design verification testing of analog and power electronics circuits. \nLead system integration, qualification campaigns, and production release of power supply modules and power systems. \nMentor younger engineers and foster knowledge sharing. \nLead a small team of power electronics engineers to drive project execution. \nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university. \nMinimum of 8 years of experience designing analog and power electronics \nExperience 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 \nExperience designing, testing and qualifying single-phase and three-phase off-line AC-DC power supplies, and DC-DC power supplies for industrial, airborne, or military systems \nKnowledge of control theory and stability of power electronics, including experience characterizing control loops and impedances in the laboratory \nExperience designing power filters for low noise outputs and for power line electromagnetic compatibility (EMC) \nExperience developing design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans \nExperience performing worst-case circuit analysis (WCA), stress analysis, failure modes and effects analysis (FMEA), and reliability analysis for power supplies \nExtensive 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 \nExperience with analysis and simulation tools such as SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, MathCAD, ANSYS Q3D and SiWave, or HyperLynx \nExperience with isolation and grounding, failure mode effects analysis and fault tolerant design, and thermal management of power electronics \nExperience designing and testing power electronics units to meet industry standards and requirements in the automotive, industrial, aircraft, or military markets (e.g., FCC, CISPR, UL safety standards, ECSS, NASA, MIL standards) \nExcellent written and verbal communication skills \nPREFERRED EXPERIENCE\nExperience designing and testing isolated and non-isolated DC-DC power converters (e.g. discrete linear regulators, Buck, Boost, Buck-boost, Flyback, Forward) \nExperience designing or specifying custom power magnetics for power supplies and power line filters \nKnowledge of power stage design and control methods for power factor correction (PFC) converters and active rectifiers \nExperience generating statements of work and requirements for external vendors, vendor selection, and vendor management for power supply and power system rack developments \nExperience with electronics schematic capture and printed circuit board (PCB) layout tools such as Altium, OrCAD, Allegro or Xpedition \nExperience running board-level power integrity simulation using tools such as Ansys SiWave, or HyperLynx \nKnowledge of soft switching and resonant power converter topologies (e.g. LLC, CLLC, series resonant, phase shifted full bridge, dual active bridge, etc.) \nProgramming skills to support hardware test and data processing (Python, MATLAB,
