- 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. Innovation is part of our DNA! Our goal is to be Earth's most customer centric company
- we are just getting started. We need people who want to join an ambitious program that continues to push the state of the art in distributed systems and hardware design. As a Sr RF engineer on the Leo Government Solutions team you will create Radio Frequency (RF) circuit solutions to support Amazon Leo's satellite communication system. This is a unique opportunity to define a new system with few legacy constraints. The ideal candidate will design, analyze
- optimize RF systems and subsystems for satellite communication payloads and ground systems. This role requires deep expertise in electromagnetic theory, RF link budgets
- end-to-end satellite communication architectures. You will tackle challenging, novel situations every day and have the opportunity to work with multiple technical teams at Amazon in different locations, partner teams
- end customers. Key job responsibilities Design, develop
- test RF subsystems for satellite communication payloads, including transponders, amplifiers, filters
- antenna feed networks. Perform RF link budget analysis for uplink, downlink
- inter-satellite links across multiple frequency bands (L, S, C, X, Ku, Ka, V). Develop and validate RF simulation models using tools such as HFSS, CST, ADS
- equivalent. Design and characterize antenna systems including phased arrays, reflector antennas
- feed assemblies. Strong understanding of transmission line theory, Smith Chart techniques
- impedance matching. Design passive microwave structures including couplers, dividers, transitions (waveguide-to-microstrip, coax-to-stripline)
- integrated filtering. Experience with RF PCB layout including controlled impedance routing, via transitions, grounding strategies
- EM isolation. Familiarity with RF component design: LNAs, HPAs (TWTAs/SSPAs), mixers, filters
- multiplexers. Develop and support integration and test activities for RF hardware, including environmental testing (thermal vacuum, vibration, EMC). Collaborate with systems engineers to define RF performance requirements and interface specifications. Experience with RF test equipment (spectrum analyzers, network analyzers, signal generators, power meters). Knowledge of modulation schemes (QPSK, 8PSK, 16APSK, DVB-S2/S2X) and multiple access techniques (FDMA, TDMA, CDMA). Experience with antenna design and characterization.
- Experience in developing functional specifications, design verification plans and functional test procedures - Bachelor's degree in electrical engineering or equivalent - 7+ years of wireless communications systems and implementation experience
- Master's degree in electrical engineering, computer engineering, or equivalent - Experience working with interdisciplinary teams to execute product design from concept to production - Experience with the project management of technical projects Amazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.
