Job summary

Amazon Leo Power Team in Redmond, WA is seeking a Senior Power Electronics Engineer to own the power converters for the satellite constellation. You will drive topology, magnetics, and prototype validation from concept to orbit, collaborating with mechanical, thermal, and systems teams to meet tight constraints.

The role demands 5+ years in switching DCDC power design, experience with isolated/non-isolated topologies, and a strong track record in aerospace/high-reliability hardware.

Qualifications

• Bachelor's degree in electrical engineering or equivalent
• 5+ years of experience designing switching DCDC power converters including topology selection, magnetics design, and control loop compensation
• Experience taking power electronics designs from concept through production
• Experience with isolated and non-isolated converter topologies in production hardware
• Experience with measurement, troubleshooting, and debug of power electronics in a lab environment
• Experience in developing functional specifications, design verification plans, and test procedures
• Graduate degree in Electrical Engineering with focus on power electronics
• Custom magnetics design (transformer and inductor development, core/material selection, loss analysis)
• Experience with resonant converters, flyback, forward, and multi-phase topologies
• EMC/EMI design and mitigation for switching converters
• Simulation-driven design methodology (LTspice, PLECS, or equivalent)
• Experience in aerospace, satellite, or high-reliability hardware environments
• Deep understanding of power semiconductor tradeoffs (Si, SiC, GaN)
• Experience with reliability analysis, derating, and worst-case circuit analysis
• Experience mentoring or technically leading other engineers

Responsibilities

• Own power converter design end to end: topology selection, magnetics design, control loop compensation, prototype build, characterization, and validation.
• Lead architecture trades that balance efficiency, mass, thermal, and reliability.
• Design, simulate, and build prototype converters; troubleshoot and fix issues.
• Lead design reviews and set the technical bar for power on the satellite.
• Define power specifications and interface requirements that govern subsystems interactions.
• Analyze power system interactions and ensure EMI/EMC compliance across designs.
• Mentor engineers and provide technical direction to programs integrating your designs.
• Work with mechanical, thermal, and systems teams to solve problems within real-world constraints.
