Antenna & RF Engineer, Amazon Leo

About the role

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.

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.

Requirements

• Bachelor’s degree
• Experience with analog, digital, and high-speed circuit design
• Experience working on >10 GHz antenna designs in consumer electronics

Qualifications

• Master’s degree in Electrical Engineering or a related field, or 5+ years of analog or RF layout design experience
• 4+ years of antenna design related to 3G/4G technologies, Wi-Fi, and Bluetooth products experience
