Sr. Comm Systems Engineer, Wireless Systems

Project Leo (former Kuiper) 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 Ka band and FR1 band communication payload and customer terminal systems.

The Role:
Be part of the team defining the overall communication system and architecture of Amazon Leos 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 project 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 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.

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.
