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 SerDes 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 next-generation processing platforms to shape 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 in phased array DSP architecture and digital beamforming, we want to hear from you.

Key job responsibilities
Own the phased array digital and DSP architecture across both D2D and Broadband payloads — spanning digital beamforming, signal processing, and data transport
Translate satellite system performance targets into phased array digital architecture decisions across the beamforming stack — including EIRP, G/T, multi-beam efficiency, and signal quality
Partner with silicon teams on beamformer chip architecture, interface definitions, and performance targets through design, integration, and characterization
Partner with communication systems teams on waveform requirements, link performance, and digital processing trade-offs to support end-to-end capacity goals
Partner with software teams on beamforming algorithm architecture including beam scheduling, null steering, and adaptive beamforming through to validated hardware performance
Drive phased array beam quality, sidelobe performance, and multi-beam efficiency through digital architecture decisions across all operating conditions
Architect DPD and CFR to maintain transmit signal quality across beam steering angles, power levels, and thermal conditions
Define fronthaul architecture and high-speed SerDes backend for payload data transport and distribution across digital subsystems
Architect backend throughput management and capacity allocation across beams and digital subsystems
Define redundancy and graceful degradation strategies for digital processing and transport paths
Define radiation mitigation approach for digital processing platforms
Evaluate emerging technologies for future architecture roadmap, and support production and on-orbit performance — hands-on, on-call
A day in the life
A typical day involves a mix of architecture work, cross-discipline collaboration, and hands-on analysis. You might spend the morning reviewing digital beamforming architecture trade-offs with the silicon team, then move to a session with communication systems engineers working through link performance and waveform requirements. Afternoons often involve DPD or backend throughput analysis, reviewing signal quality data from integration testing, or working through a redundancy architecture trade study. Lab time is part of the rhythm — characterizing beamforming performance, validating signal quality through the digital chain, or supporting phased array integration. When a satellite is live, you are available. Some weeks are heavier on roadmap work and emerging technology evaluation; others are dominated by resolving a specific performance challenge in the current program.
About the team
The Payload Architecture team is part of the Antenna organization at Amazon Leo. We are a small group of senior architects responsible for the phased array architecture across Amazon Leo’s satellite programs. We define the architecture, drive requirements, run trade studies, and make sure everything works from prototype through orbit. Our scope extends to customer link performance — working with systems and customer terminal teams to close end-to-end link budgets. We work closely with every engineering team on the payload and pride ourselves on being hands-on problem solvers.
