Full description from employer
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 RF Systems Integration and Test, you will work with a wide variety of functional groups and will be deeply involved in system integration and test of next generation Amazon Leo Satellites.
The Role:
This is a unique opportunity to define a groundbreaking, high-throughput wireless solution with few legacy constraints meet with 3GPP standards. The team works with customer requirements and wireless implementation teams to bring-up, integration and tuning, and debugging of advanced PHY/MAC and beamforming radio systems for state-of-the-art satellite communication system.
In this role you will:
• As a technical contributor, be at the forefront of bring-up, integration, and debugging of advanced PHY/MAC and beamforming radio systems for state-of-the-art satellite communication system.
