CesiumAstro is seeking a Staff Power Electronics Engineer to lead the development of next-generation power electronics hardware for satellite communication (SATCOM) terminals serving military and commercial applications. This is a hands-on technical leadership role spanning the full development lifecycle: power system architecture definition, circuit design, PCB layout, verification testing, production transition, and manufacturing support.
Key responsibilities include:
- Leading power system architecture development and deriving power subsystem requirements
- Designing DC-DC converters, AC-DC power supplies, and power distribution systems ranging from watts to 20+ kW across voltage ranges of 0.8V to 400V
- Performing comprehensive analysis including worst-case circuit analysis (WCA), stress analysis, small-signal modeling, FMEA, reliability analysis, and power integrity analysis
- Developing design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans
- Leading board bring-up and design verification testing of analog and power electronics circuits
- Leading system integration, qualification campaigns, and production release of power supply modules
- Mentoring junior engineers and fostering knowledge sharing across the team
- Leading a small team of power electronics engineers to drive project execution
The role requires deep expertise in power electronics design for aerospace and defense applications, with emphasis on reliability, compliance with military/aerospace standards, and hands-on laboratory validation.
REQUIREMENTS:
- Bachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university
- Minimum 8 years of experience designing analog and power electronics
- Experience with electrical power systems and subsystems, including power architecture development, SWAP-C trade studies, converter topology selection, and power management/control block definition
- Proven experience designing, testing, and qualifying single-phase and three-phase AC-DC power supplies and DC-DC power supplies for industrial, airborne, or military systems
- Knowledge of control theory and power electronics stability, including laboratory characterization of control loops and impedances
- Experience designing power filters for low-noise outputs and EMC compliance
- Experience developing design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans
- Hands-on experience performing WCA, stress analysis, FMEA, and reliability analysis for power supplies
- Extensive hands-on laboratory experience with oscilloscopes, impedance analyzers, spectrum analyzers, electronic loads, and signal generators
- Proficiency with analysis and simulation tools (SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, MathCAD, ANSYS Q3D, SiWave, or HyperLynx)
- Experience with isolation, grounding, FMEA, fault-tolerant design, and thermal management of power electronics
- Experience designing and testing power electronics to meet industry standards (FCC, CISPR, UL, ECSS, NASA, MIL standards) in automotive, industrial, aircraft, or military markets
- Excellent written and verbal communication skills
PREFERRED EXPERIENCE:
- Experience with isolated and non-isolated DC-DC converter topologies (linear regulators, Buck, Boost, Buck-boost, Flyback, Forward)
- Experience designing or specifying custom power magnetics
- Knowledge of power factor correction (PFC) and active rectifier design
- Experience generating statements of work and managing external vendors for power supply development
- Proficiency with schematic capture and PCB layout tools (Altium, OrCAD, Allegro, Xpedition)
- Board-level power integrity simulation experience (SiWave, HyperLynx)
- Knowledge of soft-switching and resonant converter topologies (LLC, CLLC, series resonant, phase-shifted full bridge, dual active bridge)
- Programming skills for hardware test and data processing (Python, MATLAB)
Note: Applicant must be a U.S. citizen, lawful permanent resident, conditional resident, asylee, refugee, or eligible to obtain required authorizations from the U.S. Department of State due to space technology export regulations.
