Sr. Comm Systems Engineer, Wireless SystemsJob ID: | Amazon Kuiper Manufacturing Enterprises LLCProject 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 communication payload and customer terminal systems.The RoleBe 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, and packet loss.This role will lead the effort in designing and developing advanced technology and solutions for the communication system. It includes developing advanced physical‐layer and protocol‐stack systems as proof of concept and reference implementation to improve the performance and reliability of the LEO network. The role applies concepts from digital signal processing, information theory, and wireless communications to develop novel solutions for achieving ultra‐high performance in the LEO network. It also involves developing simulation tools focused on modeling physical‐layer aspects—advanced receiver modeling, interference‐cancellation techniques, FEC abstraction models, etc.—and plays a critical role in the integration and verification of hardware and software subsystems during system integration, link bring‐up, and verification.Export Control RequirementDue to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.Basic Qualifications PhD, or Master's degree and 5+ years of quantitative field research experience5+ years of professional experience working in wireless communications at the system or implementation level
