RF Comms Systems Integration and Test Engineer, Amazon Leo

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 Comms Systems Integration and Test Engineer 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.
Architect document and execute 3GPP based testing for satellite to ground networks. Work with vendors to define equipment requirements to achieve 3GPP conformance testing. Ability to adapt test plans daily based on capabilities of HW/SW delivered by the dev teams.
Collaborate across disciplinesincluding PHY algorithms RF design digital beamforming and antenna MAC and firmware teams - to ensure seamless integration and best-in-class wireless performance.
Understand Doppler pre and post compensation techniques with CFO/SFO in LEO comms systems and test them in the laboratory environment for 3GPP. Knowing channel emulators is a plus.
Ability to trade link budget and verify RF line-up for payloads in RF and IF configurations.
Characterize performance analyze data root-cause system-level issues and ensure high product quality.
Work with a team and take responsibility for power clock RF air network debugging in lab.
Contribute development-test bring up procedures with Linux Python bash scripting etc.
Experience with wireless synchronization and signal generators / spectrum analyzers to verify that time/frequency requirements are being met.
Experience knowledge and skills on wireless system design integration bring up and debug of wireless PHY and RF systems on SoC platforms.
Strong understanding of OFDM and MIMO-based wireless systems across both baseband and RF domains with a solid foundation in related communication theory and signal processing.
Work in lab environment and stay in front of the setups for debugging with ref equipment
Work on scripting to change a SW/HW pieces incrementally and understand its effect on payload (via probing RF IF clock channel quality messages) with help of Specan siggen scope frequency counter attenuators etc
Work cross-functionally with RF ASIC SW Comsys Testbed teams and vendors to move forward in testing and integration
