## Description

As an Antenna Systems Engineer, you will be responsible for key aspects of phased array antenna system design, simulation, measurement, calibration and optimization. You will be working in a collaborative environment with a multi-disciplinary team to deliver advanced high-performance phased array antenna systems. In this role, your responsibilities will include:
· Designing and implementing phased array calibration systems, signals, processing and algorithms
· Performance analysis and design trade-off studies of phased arrays
· End-to-end modeling, simulation and analysis of baseband/RF/antenna systems
· Lab measurement and validation of performance of antennas, and phased array systems and subsystems
· Working with antenna, modem, RF and Digital teams to simulate, measure and fine-tune radio designs
Export Control Requirement:
Due to applicable export control laws and regulations, candidates must be U.S. citizens, U.S. permanent residents (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum., Design and develop novel calibration algorithms and techniques for complex phased array antenna systems, including element-level amplitude and phase correction, to ensure optimal beam-forming performance across all operating conditions.

 - Perform end-to-end over-the-air (OTA) validation of phased array antenna systems, including beam pattern verification, EIRP, EVM, and sensitivity measurements, ensuring compliance with system-level specifications.
 - Support factory production at scale by developing robust, repeatable calibration and test processes, troubleshooting yield issues, and driving continuous improvement to maintain throughput and quality on the production floor.
 - Collaborate with cross-functional teams - including antenna design, ASIC, software, and systems engineering - to debug and root-cause issues impacting phased array antenna performance, driving resolution from identification through implementation.
 - Design, maintain, and operate CICD (compact indoor chamber/direct) test chambers, including calibration schedules, reference device tracking, and measurement uncertainty documentation.
 - Develop and maintain automated test frameworks and scripts for antenna characterization and calibration workflows, improving efficiency and repeatability of measurement processes.
 - Generate and maintain technical reports, test procedures, and calibration documentation to support design reviews, certification, and production readiness milestones.
 - Analyze antenna measurement data - including beam patterns, sidelobe levels, null depths, and polarization purity - to identify performance trends, anomalies, and root causes across development and production units.
