Power Electronics Engineer for Space RF Systems

Northwood Space; Torrance (CA); On-site; USD 104,000 - 153,000; Full time

Job summary

Northwood Space in Torrance, CA is seeking an Electrical Engineer (Power Electronics) to own the power conversion and distribution electronics for Prism, Northwood's 2.4 meter parabolic antenna for high-throughput satellite links. The role involves designing, prototyping, testing, and production support for power systems powering high power RF hardware, with hands-on lab bring-up and systems modeling.

You will collaborate across RF, digital, and motion control teams to ensure robust, space-grade

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.

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
