Power Electronics Engineer

Employer description

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
