Senior Antenna & RF Engineer, Amazon Leo

Amazon Inc.; San Diego (CA); On-site; USD 159,000 - 215,000; Full time

Job summary

Amazon Inc. is seeking an Antenna Systems Engineer in Redmond to design, test, and validate antennas and RF front-ends for space-ground links. You will work across EM design, RF system analysis, and lab validation, addressing high-volume antenna design from concept to deployment.

The role requires advanced degree and 5+ years in antenna or RF system design, with MATLAB/Python and CST/HFSS experience. This is an on-site, full-time position in the United States.

Qualifications

• Master's degree in electrical or computer engineering or equivalent.

Responsibilities

• Design and optimize antenna and array architectures to meet RF system goals.
• Own end-to-end RF performance from ADC/DAC through RF front-end to antenna radiation.
• Use EM/RF design tools (HFSS, CST, AWR) to simulate performance and patterns.
• Collaborate with calibration, DSP, ASIC, and validation teams to define system strategies and measure performance.
• Define and maintain antenna specifications at module, aperture, and system levels.
• Support prototype builds, chamber testing, and over-the-air validation.
• Provide feedback for antenna boards and test fixtures and write design reports.

Job description

Description

Amazon LEO is an initiative to increase global broadband access through a constellation of 3,236 satellites in low Earth orbit (LEO). Its mission is to bring fast, affordable broadband to unserved and underserved communities around the world. Amazon LEO will help close the digital divide by delivering fast, affordable broadband to a wide range of customers, including consumers, businesses, government agencies, and other organizations operating in places without reliable connectivity.

As an Antenna Systems Engineer supporting the development, test, and design of antenna and RF Front-End, you will design, integrate, and characterize antennas and arrays across multiple domains (phased arrays, reflectors, aperture antennas, and other relevant topologies). You will possess “ADC-to-antenna” RF performance, collaborating with RF, systems, and calibration teams to deliver high-performance RF systems and links for both space and ground segments.

You’ll split your time between EM design tools, RF system analysis, and lab validation, working on high volume antenna design from concept to deployment.

Key job responsibilities

• Design and optimize antenna and array architectures (element selection, lattice, feeding networks, beam-forming strategies) to meet RF system goals.

• Own end-to-end RF performance from ADC/DAC through RF front-end to antenna radiation, working closely with RFIC, PA/LNA, and system teams.

• Use EM and RF design tools (e.g., HFSS, CST, AWR, or similar) to simulate element/array performance, mutual coupling, scan loss, and pattern characteristics.

• Collaborate with calibration, software, DSP, ASIC, and validation teams to define system strategies (array calibration, beam equalization, phase/amplitude error mitigation, IFFT gains, and more) and measure on-bench and in-chamber performance.

• Define and maintain antenna specifications and requirements at the module, aperture, and system level.

• Support prototype builds, bring-up, and test campaigns for active antennas, including chamber testing and over-the-air validation.

• Provide DFM and DFT feedback for antenna boards, modules, and test fixtures.

• Write design reports, test summaries, and present results to leadership and cross-functional partners.

• Develop and deploy code to support testing, simulation, and validation of antenna systems.

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.

Basic Qualifications

• Master's degree in electrical engineering, computer engineering, or equivalent

• 5+ years of experience in antenna design, RF system design, or front end design

• Experience in MATLAB or Python

• Experience with one of the mainstream antenna simulation tools (CST, HFSS...)

Preferred Qualifications

• Experience in phased array development, including antenna and RF system design
