Power Electronics Engineer, Leo Power Team

Power Electronics Engineer, Amazon Leo Power Team

Job  | Amazon Kuiper Manufacturing Enterprises LLC

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.

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.

This is a fast paced and challenging position where you will be working on power electronics designs that are used on the Amazon Leo Satellite. Your power designs will need to meet requirements in terms of efficiency, size, mass, thermal and survive challenging environments with high reliability.

Key job responsibilities

In this role you will be a Power Electronics Engineer in an engineering team responsible for new product development. You will be a subject matter expert in the area of power electronics focusing on DCDC power conversion and associated power electronics components.

You will own efficiency, mass and cost models of various power electronics designs and investigate different topologies to optimize the system. You will be responsible for design of power electronics prototypes, including component selection, schematic capture and layout. You will be responsible for driving designs through PCBA manufacturing and assembly, and for board bring‑up, testing, design verification and proposing and implementing solutions to design issues.

This is a fast‑paced, intellectually challenging position, and you’ll work with thought leaders in multiple technology areas. You’ll have relentlessly high standards for yourself and everyone you work with, and you’ll be constantly looking for ways to improve your products performance, quality and cost. We want individuals who are ready for this challenge and want to reach beyond what is possible today.

Everyone on the team needs to be entrepreneurial, wear many hats and work in a highly collaborative environment that's more startup than a big company. We will need to tackle problems that span a variety of domains.

A day in the life

You will work cross team to define architecture, requirements working with multiple teams, and deliver high performing and high quality power electronics designs, schematics, PCBAs for a number of different satellite subsystems.

About the team

You will work closely with peers and stakeholders from within the power team as well as solar array, battery, mechanical, thermal, EE, sensors, actuators and antenna teams to iterate on design and provide optimal solutions for the satellite.
