This role is responsible for process development, stabilization, and daily performance across interferometric metrology operations. The position requires a deep technical understanding of optical fabrication, strong analytical capability, and the ability to drive sustainable improvements in a fast-paced production environment. The engineer will directly support output, yield, and quality targets—including improving First Pass Yield (FPY) through stable, predictable, and well controlled process behavior.
