Sr. Comm Systems Engineer, Wireless Systems

Description

Project Leo (former Kuiper) 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 Systems Engineer, this role is primarily responsible for the design, development and integration of Ka band and FR1 band communication payload and customer terminal systems.

Be part of the team defining the overall communication system and architecture of Amazon Leo’s broadband wireless network. This is a unique opportunity to innovate and define groundbreaking wireless technology at global scale. The team develops and designs the communication system for Project Leo and analyzes its overall system‑level performance such as throughput, latency, system availability, packet loss, etc.

This role in particular will be responsible for leading the effort in designing and developing advanced technology and solutions for communication system. It will also be responsible for developing advanced physical‑layer + protocol‑stack systems as proof‑of‑concept and reference implementation to improve the performance and reliability of the LEO network. In particular, it will apply concepts from digital signal processing, information theory and wireless communications to develop novel solutions for achieving ultra‑high performance in the LEO network.

The role will also develop simulation tools with a particular emphasis on modeling the physical‑layer aspects such as advanced receiver modeling and abstraction, interference‑cancellation techniques, FEC abstraction models, etc. Additionally, it will play a critical role in the integration and verification of various hardware and software subsystems as part of system integration, link bring‑up and verification.

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.

• Master’s degree in Electrical Engineering, or experience working in the electrical‑engineering field

• 5+ years professional experience working in wireless communications at the system or implementation level

• PhD with emphasis in broadband wireless or wireline communication systems

• Deep understanding of multiple‑access systems such as OFDMA, TDMA, CDMA, etc.

• Experience in test‑automation setup and scripting languages such as Python/Perl/Matlab

• Experience with software‑defined radios and embedded programming in C/C++ and VHDL/Verilog is a plus

• Deep understanding of 3
  
  GPP L1 physical layer and higher‑layer protocols such as RLC, RRC, MAC

• Must have the ability to work in a small team and drive results beyond expectations

• Broad spectrum of knowledge to understand end‑to‑end network system architecture from wireless physical layer all the way up to application endpoints

• Implementation experience with wireless synchronization and parameter‑sensing techniques such as ranging/positioning based on signaling, as well as low‑power design expertise

• Ideal candidate has a wireless communication systems or digital signal‑processing background, a passion for building real‑world carrier‑grade communication systems, and industry experience developing PHY/MAC layer software targeting embedded multicore processors in C/C++. Experience with lab test equipment such as channel emulator, spectrum analyzers and signal and network traffic generators

• Experience leading technical initiatives and delivering key deliverables
