Power Electronics Engineer (Prism)

About Northwood: 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. Role: As 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. Responsibilities: - Design power electronics for Prism, including AC-DC and DC-DC conversion, power distribution, and the supplies that drive high power RF amplifiers - Define Prism's power architecture and drive system trades across efficiency, thermal load, reliability, cost, and deployment speed - Design load switching, sequencing, and power path protection schemes, including fault detection and recovery - Perform schematic capture, PCB layout oversight, and bring-up of power hardware - Build circuit and system models to analyze and verify power system performance, including stability, transient response, and efficiency - Define interfaces between the power system and Prism's RF, digital, and motion control loads - Qualify designs through environmental and EMI/EMC testing Basic Qualifications: - Bachelor's degree in electrical engineering or a related engineering discipline - 3-5+ years of power electronics hardware design experience - Hands-on experience designing switched-mode power converters (buck, boost, flyback, LLC, or similar) at hundreds of watts or more - Experience taking power hardware from schematic and layout through bring-up, characterization, and debug in the lab - Proficiency with circuit simulation tools such as LTspice, PLECS, or SIMetrix - Comfort with power electronics test equipment, including oscilloscopes with differential and current probes, electronic loads, and power analyzers Preferred Qualifications: - Master's degree or PhD in electrical engineering with a focus on power electronics - Kilowatt-class AC-DC and isolated DC-DC converter design, including power factor correction - Drain supply and bias design for GaN RF power amplifiers, including sequencing and low-ripple regulation - Protection circuitry design, including hot-swap, inrush limiting, overcurrent, and reverse-polarity protection - Input filter design and control loop compensation for converter stability - Surge, lightning, and transient protection for grid-connected outdoor equipment - Magnetics design and wide-bandgap (GaN, SiC) power stage design - Motor drive power electronics for antenna positioners or motion control systems - Thermal design and EMI/EMC mitigation for high-density power hardware - Design for manufacturing, production test development, and reliability qualification Compensation: Electrical Engineer/Level 2: $104,000-$130,000 per year Electrical Engineer/Level 3: $122,400-$153,000 per year Additional Information: If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.
