Antenna & RF Engineer, Amazon Leo

Amazon • Redmond, WA

4d

About The Position

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 own “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.

Requirements

• BS degree in electrical engineering or equivalent
• 5+ years of experience of research and/or development in antenna design
• Fluency in Matlab, Python or C++
• Fluency with one of the mainstream antenna simulation tools (CST, HFSS,…)
• 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.

Nice To Haves

• Master's degree in electrical engineering or equivalent
• Strong foundations in RF Systems
• 1+ year of design experience RF building blocks such as filters, hybrids, combiners
• Experience with active RF circuits and front-end design
• Experience in phased array development

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.

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
