Description
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 Sr. 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 that meets 3
GPP standards. The team works with customer requirements and wireless implementation teams to bring‑up, integrate, tune, and debug advanced PHY/MAC and beamforming radio systems for a state‑of‑the‑art satellite communication system.
In this role you will:
- Serve as a technical contributor at the forefront of bring‑up, integration, and debugging of advanced PHY/MAC and beamforming radio systems for a state‑of‑the‑art satellite communication system.
- Architect, document, and execute 3
GPP‑based testing for satellite‑to‑ground networks. Work with vendors to define equipment requirements to achieve 3
GPP conformance testing and adapt test plans daily based on capabilities of HW/SW delivered by development teams. - Collaborate across disciplines—including 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 communication systems and test them in the laboratory environment for 3
GPP. Knowledge of channel emulators is a plus. - 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, and network debugging in lab.
- Contribute development‑test bring‑up procedures with Linux, Python, bash scripting, etc.
- Have experience with wireless synchronization and signal generators / spectrum analyzers to verify that time/frequency requirements are being met.
- Possess skills in wireless system design, integration, bring‑up, and debugging of wireless PHY and RF systems on SoC platforms.
- Have a 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 a lab environment and stay in front of the setups for debugging with reference equipment.
- Script changes to SW/HW incrementally and understand their effect on payload (via probing RF, IF, clock, channel quality messages) with help of Specan, signal generator, scope, frequency counter, attenuators, etc.
- Work cross‑functionally with RF, ASIC, SW, Comsys, Testbed teams and vendors to move forward in testing and integration.
