Sr. Comm Systems Engineer, Wireless SystemsJob ID: 3208412 | 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 Ka band and FR1 band 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 a 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 and will also develop advanced physical‑layer and protocol‑stack systems as a proof‑of‑concept and reference implementation to improve the performance and reliability of the LEO network. The role requires using concepts from digital signal processing, information theory, and wireless communications to develop novel solutions for achieving ultra‑high performance in the LEO network. Additional responsibilities include developing simulation tools with a focus on physical‑layer modeling, advanced receiver modeling, interference‑cancellation techniques, and FEC abstraction models. The role will also play a critical part 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, a U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.Basic QualificationsPhD or Master's degree and 5+ years of quantitative field research experience5+ years professional experience working in wireless communications at the system or implementation levelPreferred QualificationsPhD with emphasis in broadband wireless or wireline communication systemsDeep understanding of multiple‑access systems such as OFDMA, TDMA, CDMA, etc.Experience in test automation setup and scripting languages such as Python, Perl, MATLABExperience with software‑defined radios and embedded programming in C/C++ and VHDL/Verilog is a plusDeep understanding of 3GPP L1 physical layer and high‑layer protocols such as RLC, RRC, and MACAbility to work in a small team and drive to go beyond expectations to deliver resultsBroad spectrum of knowledge to understand end‑to‑end network system architecture from wireless physical layer to application end‑pointImplementation experience with wireless synchronization and parameter‑sensing techniques such as ranging/positioning based on signaling and low‑power design expertiseIdeal 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 generatorsExperience with leading technical initiatives and key deliverablesAmazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.Los Angeles County applicants: Job duties include working safely and cooperatively with other employees, supervisors, and staff; adhering to standards of excellence despite stressful conditions; communicating effectively and respectfully with employees, supervisors, and staff to ensure exceptional customer service; and following all federal, state, and local laws and company policies.
