Phased Array DSP & Digital Beamforming Architect, Amazon Leo Antenna Team

Job :  | Amazon Kuiper Manufacturing Enterprises LLC

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 at scale.
We are looking for a Phased Array DSP & Digital Beamforming Architect to join the Payload Architecture team in San Diego. This is a cross-program position that sits at the intersection of satellite system performance and phased array digital implementation — translating what the constellation needs to deliver into how the digital beamforming, signal processing, and data transport must be architected across both the Direct-to-Device (cellular-band) and Broadband (Ka-band) payloads.

You will work closely with experienced architects and engineers across silicon, communication systems, and software disciplines, contributing to an architecture that must perform reliably from first power-on through years of unattended operation in low Earth orbit.
As the digital and DSP owner for the phased array, you will define how the antenna system achieves its performance targets from the digital side — establishing the architecture for digital beamforming, beam quality management, sidelobe control, null steering, beam scheduling, and multi-beam resource allocation. You will partner with silicon teams on chip architecture and performance targets, engage communication systems teams on waveform requirements and link performance, and work with software teams on beamforming algorithms and beam management.

In addition to defining requirements for silicon, communication systems, and software teams, you will partner with each discipline through design, integration, and test — jointly resolving trade-offs and driving architecture outcomes measured in EIRP, G/T, and multi-beam efficiency.
The technical scope is broad and deep. You will own DPD and CFR architecture to preserve transmit signal quality across the full range of beam steering conditions and power levels. You will define fronthaul architecture and high-speed Ser Des backend design, establishing how payload data is transported and distributed across digital subsystems. Backend throughput management — ensuring the digital backbone handles aggregate traffic load across all active beams — is a core responsibility, as is capacity allocation across beams and digital domains.

You will architect redundancy and graceful degradation strategies so that digital processing and transport paths continue delivering service when individual components fail — because in-orbit hardware cannot be repaired.
The space environment shapes every decision in this role. Radiation effects on digital processing platforms require purpose-built mitigation strategies that preserve both performance and reliability across the satellite’s operational life. Thermal and power constraints are first-order inputs to architecture choices, not afterthoughts. You will work with the verification team to validate the phased array digital architecture through test, and you will collaborate across silicon, communication systems, software, systems, hardware design, antenna, calibration, thermal, power, mechanical, and reliability teams to drive the architecture from early concept through production and on-orbit performance.

Beyond the current programs, you will evaluate emerging digital beamforming techniques and…
