Original job description

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 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 meet with 3GPP standards. The team works with customer requirements and wireless implementation teams to bring-up, integration and tuning, and debugging of advanced PHY/MAC and beamforming radio systems for state-of-the-art satellite communication system.

In this role you will:

As a technical contributor, 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. Ability to adapt test plans daily based on 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 Doppler pre and post compensation techniques with CFO/SFO in LEO comms systems and test them in the laboratory environment for 3GPP. Knowing channel emulators is a plus.
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.

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.

Preferred Qualifications

Masters/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/Matlab
Broad spectrum of knowledge to be able to understand end-to-end network system architecture from wireless RF and physical layer all the way up to application end-point
Must have 3GPP NTN and ORAN knowledge to address conformance testing
Experience with leading technical initiatives and key deliverables.
Must have the ability to work in a small team and drive to go beyond expectations to deliver results
Should have background in wireless LTE, 5G/6G, RLC, PDCP, RRC and RAN protocols
