Power Electronics Engineer, High-Power RF & Space Systems

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

Job summary

Northwood is seeking an Electrical Engineer (Power Electronics) to own the power conversion and distribution electronics for Prism, its 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

Qualifications

• Bachelor's degree in electrical engineering or related field.
• 3-5+ years of power electronics hardware design experience.
• Hands-on experience designing switched-mode power converters (buck, boost, flyback, LLC, etc.) at hundreds of watts or more.
• Experience taking power hardware from schematic/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 (oscilloscopes with differential/current probes, electronic loads, power analyzers).

Responsibilities

• Design power electronics for Prism, including AC-DC and DC-DC conversion and power distribution.
• Define Prism's power architecture and drive system trades (efficiency, thermal, reliability, cost).
• Design load switching, sequencing, and power path protection (fault detection/recovery).
• Perform schematic capture, PCB layout oversight, and bring-up of power hardware.
• Build circuit/system models to analyze 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.
