Antenna & RF Front-End Engineer, Amazon Leo

Amazon; Redmond (WA); On-site; USD 151,000 - 205,000; Full time

Job summary

Amazon is seeking an experienced RF engineer to design and optimize LEO antenna systems for a high-profile satellite program in Redmond, WA. You will own end-to-end RF performance from ADC/DAC through the front-end to antenna radiation, collaborating with RFIC, PA/LNA, software, and systems teams to meet stringent performance targets.

You will use HFSS/CST/AWR or similar tools to simulate arrays, validate patterns, and drive system strategies across calibration, software, and validation teams.

Qualifications

• Experience leading the design, automation, deployment, and support of large-scale infrastructure.
• Experience programming with at least one modern language such as Python, Ruby, Golang, Java, C++, C#, Rust.
• Experience with Linux/Unix.
• Experience with CI/CD pipelines build processes.

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 with cross-team collaboration.
• Use EM/RF design tools to simulate element/array performance, mutual coupling, scan loss, and patterns.
• Collaborate with calibration, software, 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, bring-up, and test campaigns for active antennas, including chamber and OTA testing.
• 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.

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.

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.

A day in the life

You will design and implement the RF antennas and Front-End systems that ensure the performance of Leo's antennas from lab test to fully integrated customer terminals. Your tools, code, simulations, and systems will define the performance of one of the most advanced communication systems ever built.

You’ll collaborate with RF, software, calibration, and systems engineers, and make daily decisions that directly affect the readiness of Leo's payload and terminal products. The systems you build will enable critical RF links, data collection, system analysis, and CICD pipelines that ensure LEO hardware performs flawlessly on Earth and in orbit.

About The Team

Our team owns the full performance lifecycle of LEO's antenna systems from early concept testing and calibration to final product release. We operate at the intersection of RF Systems, mixed signal ASICs, software automation, and large-scale system integration.

You’ll work closely with antenna, DSP, and system development engineers, contributing to the design, development frameworks, manufacturing support, and performance validation. We leverage AWS tools and scalable software architectures to accelerate development, automate validation, and deliver reliable test systems used across the entire LEO organization.

Basic Qualifications
