Solar Panel Test Engineer

AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight.

Position Overview

AST SpaceMobile is seeking a hands-on and highly analytical Solar Panel Test Engineer to support the performance, stability, and continuous improvement of solar panel production test systems in a high-volume manufacturing environment. This role is responsible for the setup, qualification, maintenance, and optimization of solar panel test stations, ensuring accurate product validation and production readiness.

The Solar Panel Test Engineer will lead test equipment configuration, operator test procedures, electrical performance analysis, AM0 power measurements, Electroluminescence (EL) inspections, Infrared Thermography (IRT) testing, and root cause corrective actions for hardware and software failures. This position partners closely with Manufacturing, Quality, Engineering, Automation, and Operations teams to support efficient, automated, mass-production operations while maintaining high product quality and test integrity.

Key Responsibilities

• Set up, qualify, operate, and maintain solar panel test equipment and production test stations, including EL (Electroluminescence), IRT (Infrared Thermography), IV/Power, and AM0 test systems.
• Analyze solar panel test performance data, including EL results, IRT imagery, power measurements, yield performance, and defect trends.
• Define, monitor, and report key test performance metrics including First Pass Yield (FPY), throughput, test cycle time, retest rates, yield trends, and equipment availability.
• Lead Root Cause Corrective Action (RCCA) investigations for recurring hardware, software, and process-related failures.
• Troubleshoot sensors, cameras, light sources, power supplies, instrumentation, cabling, connectors, fixtures, conveyors, and software-related issues to minimize production downtime.
