Staff - Signal Integrity Test Engineer ((CRT TEST)

Summary

The Signal Integrity Test Engineer plays a key role in high-speed digital PCB development with a strong focus on signal integrity validation and testing. This includes planning and executing lab measurements, analyzing eye diagrams, loss, impedance, jitter, and troubleshooting SI issues on completed designs. The role drives correlation between simulation and lab results, supports compliance testing, and provides critical input during design reviews to ensure robust signal performance. Strong communication skills are required to work effectively with global teams.
The engineer designs and develops electrical systems and circuits, translating concepts into schematics and specifications, while ensuring designs meet signal integrity requirements through simulation and lab validation. They own system bring-up, testing, qualification, and continuous optimization based on measurement data. This role works closely with cross-functional teams—including design, manufacturing, and customers—to deliver high-quality products, and continuously improves designs using feedback from testing, manufacturing, reliability, and system validation results.
