Senior RF Systems Integration and Test Engineer, RF and 3GPP NTN, Amazon Leo

Amazon Leo is building a Low Earth Orbit satellite constellation to deliver high speed, low latency broadband connectivity to unserved and underserved communities around the world.

As part of Payload Integration - Bachelor's degree - 7+ years of experience in RF systems integration, wireless validation, modem validation, OTA testing, or cellular lab test experience.

- Strong understanding of RF communications fundamentals, including link budgets, SNR, EVM, ACLR, gain, noise figure, linearity, synchronization, fading, interference, and antenna behavior. - Knowledge of 3GPP Release 17 NTN concepts and ability to connect standards behavior to RF and system level validation.

- Experience integrating or testing Open RAN, gNodeB, CU, DU, RU, modem, RF front end, or 5G Core systems. - Experience with VoNR and IMS is desirable, especially the ability to understand how RF and mobility behavior impacts service continuity.

- Experience with RF lab equipment such as spectrum analyzers, signal generators, vector signal analyzers, power meters, channel emulators, chambers, or OTA systems. - Ability to analyze logs, packet captures, RF measurements, modem traces, and system telemetry to debug end to end failures.

- Linux proficiency and comfort working directly in a lab environment with hardware, test equipment, and automated test systems.
