Senior Antenna & RF Engineer, Amazon Leo

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.

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
• Fluency in MATLAB or Python
• Fluency with one of the mainstream antenna simulation tools (CST, HFSS...)

Preferred Qualifications

• PhD in Electrical Engineering, Computer Science, Mathematics, or a related technical field
• Experience in phased array development, including antenna and RF system design
