Lead 5G NTN D2D Phased-Array Architect

Amazon Inc.; San Diego (CA); On-site; USD 159,000 - 215,000; Full time

Job summary

Amazon Leo Antenna Team in San Diego seeks a Sr. 5G NTN D2D Phased Array Antenna Architect to shape the satellite payload architecture for Direct-to-Device phased arrays.

You will define requirements, drive trade studies, and work across systems, HW, and calibration teams to realize space‑grade architectures. The role emphasizes hands‑on lab work, simulations in MATLAB/Python/C++, experience with RF measurement gear, and collaboration with multiple engineering disciplines to meet stringent space

Qualifications

• Master's degree in electrical engineering, computer engineering, or equivalent.
• Experience in wireless system design and architecture, system integration, and RF system analysis.
• Experience in 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 experience designing 3GPP-based wireless communication systems for terrestrial or satellite networks.
• Experience in phased array design principles, including beamforming, beam steering, and antenna system integration.

Responsibilities

• Translate high-level service and coverage requirements into D2D payload requirements — accounting for thermal, power, mechanical, reliability, and mass constraints.
• Propose and own the D2D phased array architecture spanning the full signal chain from antenna element through RF front‑end through digital beamforming backend to modem interface.
• Work with systems, HW design, antenna, silicon, and calibration teams to realize the architecture.
• Contribute to customer link performance — working with systems and customer terminal teams to meet end‑to‑end link requirements.
• Define phased array requirements that flow from system‑level needs down to subsystem and component specifications.
• Work with the verification team to develop test plans that validate those requirements.
• Define signal integrity requirements for high-speed serial interconnects based on SerDes technology selection, and review analysis performed by the SI team.
• Support RF front‑end and DPD/CFR architecture trade studies across multiple semiconductor process technologies.
• Collaborate with communication systems and regulatory teams to translate 5G NR and NTN standards into phased array requirements.
• Evaluate emerging technologies to inform the next generation architecture roadmap.
• Support production and on‑orbit debug — this role is hands‑on and on‑call.
