Job summary

Amazon Leo Antenna Team in San Diego seeks a Phased Array DSP & Digital Beamforming Architect to lead the digital side of the phased array across both D2D and Ka‑band payloads. You will define beamforming architecture, collaborate with silicon, comms and software teams, and assure performance from first power-on through on‑orbit operation.

The role requires deep expertise in DSP, beamforming, RF measurement, and experience across architecture and design for space systems.

Qualifications

• Master's degree in electrical engineering, computer engineering, or equivalent.
• 7+ years of digital design in communication systems experience.
• Experience contributing to the architecture and design of new and current systems, or embedded wireless systems.
• Experience developing link and system level simulators using MATLAB, Python, or C++.
• Experience with RF measurement equipment, including power meters, spectrum analyzers, vector signal generators, network analyzers, oscilloscopes.
• 7+ years of phased array DSP architecture, digital beamforming, or high-speed digital design.
• Experience in phased array digital beamforming architecture, including system-level design for multi-element or multi-beam antenna systems.
• Experience collaborating across silicon, communications systems, and software disciplines in phased array or wireless system development.
• Experience developing DSP system models, beamforming simulations, or link-level analyses using MATLAB, Python, or C++.

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.
