Sr. Communication Systems Engineer

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.

Come work at Amazon!

The Role:

Be part of the team defining the overall communication system and architecture of Leo's broadband wireless network. This is a unique opportunity to innovate and define groundbreaking wireless technology with few legacy constraints. The team develops and designs the communication system of 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 integration, verification and testing of the systems especially focused on MAC and higher layer testing. This role will also be responsible developing and testing advanced L1/L2/L3 concept to improve the performance and reliability of the 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.

In this role you will:

• Work within a project team and take the responsibility for the Leo's communication system design, system integration and verification.
• Work as a part of the team in building a suite of system and network simulation services in Matlab / C++ / Python
• Develop requirements from system level to HW/SW level and define test cases associated with the requirements.
• Identify additional HW and SW that are needed for the purposes of verification and guide the HW/SW development team in the development of these test solutions/tools//
• Work closely with implementation teams to simulate expected system level performance and provide quick feedback on potential improvements
• Write scripts / code for functions / features required for specific simulation, testing and verification of given RF system
