Sr. RF Comms Systems Integration and Test Engineer, Amazon Leo

Job :  | 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.

Overview

As a Sr. RF Comms Systems Integration and Test Engineer, you will collaborate with multiple functional groups and be deeply involved in system integration and testing of next‑generation Amazon Leo satellites.

The Role

• Lead bring‑up, integration, and debugging of advanced PHY/MAC and beamforming radio systems for state‑of‑the‑art satellite communications.
• Architect, document, and execute 3
  
  GPP‑based testing for satellite‑to‑ground networks; work with vendors to define equipment requirements and adapt test plans based on delivered hardware/software.
• Collaborate across PHY algorithms, RF design, digital beamforming, antenna, MAC, and firmware teams to ensure seamless integration and best‑in‑class wireless performance.
• Understand and test Doppler pre/post‑compensation techniques with CFO/SFO in LEO communication systems; utilize channel emulators where applicable.
• 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 laboratory environments.
• Contribute development‑test bring‑up procedures with Linux, Python, bash scripting, etc.
• Use wireless synchronization, signal generators, and spectrum analyzers to verify time/frequency requirements.
• Apply knowledge of OFDM and MIMO‑based wireless systems across both baseband and RF domains.
• Engage in scripting to modify SW/HW pieces incrementally and evaluate effects on payload using equipment such as Specan, siggen, scope, frequency counter, attenuators.
• Work cross‑functionally with RF, ASIC, SW, Comsys, Testbed teams, and vendors to advance testing and integration.

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

• Bachelor's degree in Electrical Engineering or a related field, or equivalent experience in electrical engineering.
• 7+ years of professional experience in L1/L2 or beamforming.
• Experience with RF lab equipment, bring‑up, test, and integration activities.

• Master's or PhD with emphasis in wireless communication systems.
• Proficiency with modeling in MATLAB and/or C/C++; experience in test automation setup and scripting languages such as Python, Perl, or MATLAB.
• Broad knowledge to understand end‑to‑end network system architecture from wireless RF and physical layer to application endpoints.
• 3
  
  GPP NTN and ORAN knowledge for conformance testing.
• Experience leading technical initiatives and delivering key deliverables.
• Ability to work in a small team and drive to exceed expectations.
• Background in wireless LTE, 5G/6G, RLC, PDCP, RRC, and RAN protocols.
• Knowledge of IP, UDP, TCP, HTTP protocols and analysis tools such as Wireshark.
• Experience with current software development processes and tools including Agile, TDD, BDD, CI, and Git.
• Implementation experience with wireless synchronization and parameter sensing techniques such as ranging/positioning based on signaling and low‑power design expertise.
• Extensive experience with Lab test equipment such as channel emulator, spectrum analyzers, and signal/network traffic generators.
