Sr. D2D Phased Array Antenna Architect, Leo Antenna Team

Position: Sr. D2D Phased Array Antenna Architect, Amazon Leo Antenna Team
Amazon Leo is Amazon's low Earth orbit satellite constellation initiative designed to bring fast, affordable broadband connectivity to unserved and underserved communities around the world. We are building a next-generation satellite system from the ground up — designing everything from the spacecraft and payload to the ground infrastructure and customer terminals. This is a rare opportunity to join a team that is shaping the future of global connectivity  are looking for a D2D Phased Array Architect to join the Payload Architecture team in San Diego.

You will be a key technical contributor to the architecture of our Direct-to-Device satellite payload — a cellular-band phased array system designed to deliver connectivity directly to unmodified smartphones from space. You will work alongside experienced architects and engineers, helping shape the D2D phased array architecture as it evolves through current and future satellite generations.

This role requires strong phased array architecture expertise spanning the RF front-end and digital backend — including high-speed serial interconnects, digital beamforming, transmit chain linearization techniques like DPD and CFR, and RF front-end design across multiple semiconductor process technologies. Knowledge of 5G  non-terrestrial network communications is important as you will work at the intersection of cellular standards and space-based phased array design.

You will define phased array requirements and work with the verification team to validate them through test. You will collaborate with systems, HW design, communication systems, regulatory, silicon, antenna, calibration, thermal, power, mechanical, reliability, and verification teams to ensure architecture and requirements are achievable within space environment constraints.

Beyond the current payload, you will evaluate emerging technologies and contribute to the architecture roadmap for future satellite generations. This is a hands-on role — you will be in the lab, in the data, and on call when satellites are live. If you have experience with cellular or satellite phased array systems, we want to hear from you.
