Senior RF & Beamforming Systems Engineer for LEO Satcom

Amazon; Redmond (WA); On-site; USD 137,000 - 186,000; Full time

Job summary

Amazon Kuiper Manufacturing Enterprises LLC is seeking a highly skilled wireless systems engineer to define and bring up high-throughput satellite communication hardware. You will work across PHY, RF, and software teams to drive integration of 3GPP-based testing and ensure conformance for satellite-to-ground links.

The role emphasizes lab-based verification, FPGA work, MATLAB/C++ modeling, and scripting in Python, with focus on Doppler handling, beamforming and end-to-end system performance.

Qualifications

• Bachelor's degree in Electrical Engineering or a related field, or experience working in electrical engineering field
• 7+ years professional experience working in L1/L2 or beamforming
• Experience with RF lab equipment, bring-up, test and integration activities
• Experience with verification and integration on FPGA

Responsibilities

• 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.
• 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 comms systems and test them in the laboratory environment for 3GPP.
• 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. Be involved in verification and integration on the FPGA.
