About The Position

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit
satellites that will provide low-latency, high-speed broadband connectivity to
unserved and underserved communities around the world. As a Systems Engineer,
this role is primarily responsible for the design, development and integration
of communication payload and customer terminal systems.

The Role:
Be part of the team defining the overall communication system and architecture
of Amazon Leo’s broadband wireless network. This is a unique opportunity to
innovate and define groundbreaking wireless technology at global scale. The team
develops and designs the communication system for Leo and analyzes its overall
system level performance such as for overall throughput, latency, system
availability, packet loss etc.

This role in particular will be responsible for leading the effort in designing
and developing advanced technology and solutions for communication system. This
role will also be responsible developing advanced physical layer + protocol
stacks systems as proof of concept and reference implementation to improve the
performance and reliability of the LEO network. In particular this role will be
responsible for using concepts from digital signal processing, information
theory, wireless communications to develop novel solutions for achieving
ultra-high performance LEO network. This role will also be part of a team and
develop simulation tools with particular emphasis on modeling the physical layer
aspects such as advanced receiver modeling and abstraction, interference
cancellation techniques, FEC abstraction models etc. This role will also play a
critical role in the integration and verification of various HW and SW
sub-systems as a part of system integration and link bring-up and verification.
