Job Description
Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity.
In this role you will design the power converters that fly on Amazon Leo satellites. You'll own topology selection, magnetics design, and prototype validation for custom DCDC converters that power the constellation. Your designs go from simulation to bench to orbit.
Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
Key job 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. Your recommendations determine what gets built.
Design, simulate, and build prototype converters. When something doesn't behave, get to the bottom of it and fix it.
Lead design reviews and set the technical bar for power on the satellite.
Define power specifications and interface requirements that govern how subsystems interact with the power system.
Analyze power system interactions and ensure EMI/EMC compliance across designs.
Mentor engineers and provide technical direction to programs integrating your designs.
Work closely with mechanical, thermal, and systems teams to close budgets and solve problems within real-world constraints.
A day in the life
You might spend the morning working through magnetics tradeoffs for a new isolated converter, then head to the lab to characterize a prototype you designed. After lunch you're leading a design review, helping a team understand the limits of a converter they're adopting. Then you're back at your desk refining a simulation that caught a thermal issue before it became expensive. The work is varied, technical, and yours.
About the team
The Power Electronics Design team owns power for the entire satellite. We design our own converters, qualify our own magnetics, and write our own specs. A single converter design can cover multiple subsystems, and a single qualification unlocks a component for the entire constellation. Small team, outsized impact.
Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to
- 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 both 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
