Power Electronics Engineer (Prism)

Electrical Engineer (Power Electronics)Northwood is a modern space infrastructure company bringing the benefits of space to the masses through advanced communications technology. We are building a global network of phased array ground stations that enable real-time, reliable communication for satellite missions such as national security, global connectivity, and disaster response. With a vertically integrated approach, Northwood designs, builds, and rapidly deploys scalable systems that power the next generation of space missions. If you like solving complex challenges and seeing your work deployed around the world with real impact, Northwood is the place to do it.RoleAs an Electrical Engineer (Power Electronics), you will own the power conversion and distribution electronics for Prism, Northwood's 2.4 meter parabolic antenna for high-throughput satellite links. You will design the power systems that feed Prism's high power RF hardware and support electronics, taking them from architecture through prototype, testing, and production. This is a hands-on role for someone who has designed, built, and debugged power electronics that have to run reliably in the field.ResponsibilitiesDesign power electronics for Prism, including AC-DC and DC-DC conversion, power distribution, and the supplies that drive high power RF amplifiersDefine Prism's power architecture and drive system trades across efficiency, thermal load, reliability, cost, and deployment speedDesign load switching, sequencing, and power path protection schemes, including fault detection and recoveryPerform schematic capture, PCB layout oversight, and bring-up of power hardwareBuild circuit and system models to analyze and verify power system performance, including stability, transient response, and efficiencyDefine interfaces between the power system and Prism's RF, digital, and motion control loadsQualify designs through environmental and EMI/EMC testingBasic QualificationsBachelor's degree in electrical engineering or a related engineering discipline3-5+ years of power electronics hardware design experienceHands-on experience designing switched-mode power converters (buck, boost, flyback, LLC, or similar) at hundreds of watts or moreExperience taking power hardware from schematic and layout through bring-up, characterization, and debug in the labProficiency with circuit simulation tools such as LTspice, PLECS, or SIMetrixComfort with power electronics test equipment, including oscilloscopes with differential and current probes, electronic loads, and power analyzersPreferred QualificationsMaster's degree or PhD in electrical engineering with a focus on power electronicsKilowatt-class AC-DC and isolated DC-DC converter design, including power factor correctionDrain supply and bias design for GaN RF power amplifiers, including sequencing and low-ripple regulationProtection circuitry design, including hot-swap, inrush limiting, overcurrent, and reverse-polarity protectionInput filter design and control loop compensation for converter stabilitySurge, lightning, and transient protection for grid-connected outdoor equipmentMagnetics design and wide-bandgap (GaN, SiC) power stage designMotor drive power electronics for antenna positioners or motion control systemsThermal design and EMI/EMC mitigation for high-density power hardwareDesign for manufacturing, production test development, and reliability qualificationCompensationElectrical Engineer/Level 2: $104,000-$130,000 per yearElectrical Engineer/Level 3: $122,400-$153,000 per yearAdditional InformationIf you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.Northwood Space is an Equal Opportunity Employer; employment with Northwood Space is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
