Sr. Phased Array Antenna Verification Architect, Amazon Leo Antenna Team

Amazon Leo is Amazons 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 Payload Verification Architect to join the Payload Architecture team in San Diego. You will be a key technical contributor to the verification and validation strategy across both of our satellite payload programs a cellular-band phased array for direct-to-device connectivity and a Ka-band multi-beam phased array for broadband service.

You will derive verification requirements from the phased array architecture and work with both payload architects to ensure alignment between what is designed and what is tested. You will define what needs to be tested how it will be tested and what constitutes pass or fail.

You need to be well-versed in industry standard RF and communication system tests blocker tests ACLR EVM spurious emissions intermodulation sensitivity selectivity and conducted power measurements. You will contribute to conductive and over-the-air test systems help plan aerospace qualification campaigns including thermal vacuum vibration shock and radiation testing and support production test infrastructure.

You will collaborate with payload architects systems HW design communication systems regulatory silicon antenna calibration thermal power mechanical reliability and production teams.

Beyond current programs you will evaluate emerging test technologies to evolve the verification strategy for future satellite generations. This is a hands-on role you will be in the lab in the data and on call. If you have experience testing complex RF systems and qualifying hardware for space we want to hear from you.

Export Control Requirement:
Due to applicable export control laws and regulations candidates must be a U.S. citizen or national U.S. permanent resident (i.e. current Green Card holder) or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities
Work with payload architects to understand the phased array architecture and define what needs to be verified how and what constitutes pass or fail across both D2D and broadband programs
Own the verification strategy tracing from high-level payload requirements through subsystem and component-level test plans
Work with systems HW design antenna silicon and calibration teams to build verification plans covering the full operating envelope
Define test methodology for standard RF and communication system tests: blocker ACLR EVM spurious emissions intermodulation sensitivity selectivity and conducted power
Contribute to conductive test infrastructure for element and module-level characterization
Help architect over-the-air test systems for array-level beam pattern and performance verification
Contribute to aerospace qualification campaign planning: thermal vacuum vibration shock radiation and life testing
Support production test infrastructure with pass/fail criteria yield analysis and test time optimization
Support verification of customer link performance through appropriate payload-level test methodology
Support on-orbit verification including launch health checks beam validation and telemetry monitoring
Evaluate emerging test technologies to evolve the verification strategy for future generations
Support anomaly resolution and root-cause analysis this role is hands-on and on-call

A day in the life
You split your time between current programs and next generation. On any given day you might review new requirements with payload architects and define how to verify them run RF measurements review qualification data analyze blocker or EVM test results or optimize production tests. You support customer link verification and work across HW design antenna silicon and calibration teams to build verification plans covering the full operating envelope. Some weeks you evaluate new measurement techniques and define the verification roadmap. Other days you are in the lab debugging a marginal result or supporting an on-orbit anomaly investigation.

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 Leos 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. We are based in San Diego.
