Sr. Power System Engineer, Amazon Leo

Amazon • Redmond, WA

5h

About The Position

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.

This is a Senior Electrical Systems Engineering position where you will own
requirements, trade studies, and simulation analysis for the Leo satellite power
system. In this role, you will build electrical models of the satellite power
system and develop capability to assess solar array power generation over
vehicle operating conditions and a range of orbital parameters. You will be
responsible to create and manage simulations that analyze vehicle power demand
in different power modes and investigate trade-studies to optimize performance
of the system. You will perform trade studies to influence system architecture
and sizing of solar array, battery, power conversion, and power distribution
blocks.

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 product’s 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. We will need to tackle problems that span a
variety of domains.
