Sr. RF Comms Systems Integration and Test Engineer, Amazon Leo
Job ID: | Amazon Kuiper Manufacturing Enterprises LLC
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 be deeply involved in system integration and test of next‑generation Amazon Leo satellites.
Role Overview
This is a unique opportunity to define a groundbreaking, high‑throughput wireless solution that meets 3GPP 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.
Responsibilities
- Bring‑up, integrate, and debug advanced PHY/MAC and beamforming radio systems for a 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; adapt test plans daily based on the capabilities of HW/SW delivered by the dev 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 and test Doppler pre‑ and post‑compensation techniques with CFO/SFO in LEO comms systems in the laboratory environment.
- 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.
- Take responsibility for power, clock, RF, air, and network debugging in lab.
- Contribute development–test bring‑up procedures with Linux, Python, bash scripting, etc.
- Work with wireless synchronization tools and signal generators/spectrum analyzers to verify time/frequency requirements.
- Support wireless PHY and RF system design, integration, bring‑up and debugging of wireless PHY and RF systems on SoC platforms.
- Apply 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.
- Perform lab debugging with reference equipment and incremental scripting to assess effects on payload.
- Collaborate cross‑functionally with RF, ASIC, SW, Comsys, Testbed teams and vendors to advance testing and integration.
