Job Summary:

Reporting to the VP Quality Engineering & Technology, this person will be responsible for managing quality operations within the InP fabrication facility supporting laser and gain chip production for high-speed optical AI infrastructure applications. This position requires thorough understanding of III-V semiconductor processes, photonic device physics, and quality management practices in high-volume wafer manufacturing environments. Support and establish procedures for new product introduction, technology development, process optimization and failure analysis investigations.

Responsibilities:

Serve as Management Representative for ISO systems, coordinating cross-functional teams to maintain documentation, implement corrective actions, and drive continuous improvement initiatives aligned with ISO9001:2015 Quality Management System and ISO14001:2015 Environmental Management System certifications.
Manage day-to-day quality operations across InP wafer fabrication including epitaxy (MOCVD/MBE) and wafer processing. Interface between fab operations and Engineering teams to drive yield improvement and quality enhancement initiatives.
Lead inline and final inspection strategies for laser and gain chip products including LIV (Light-Current-Voltage), spectral performance, and optical power characterization.
Actively participate in new process development for advanced photonic devices including DFB/DBR lasers, semiconductor optical amplifiers (SOAs), and photonic integrated circuits (PICs).
Manage Quality Continuous Improvement activities through data analysis, SPC monitoring, root cause identification and implementation of corrective and preventative actions across the Product Development Cycle.
Participate and drive DFM, DFT, and FMEA activities within the engineering groups specific to photonic devices.
Manage supplier quality for critical materials including InP substrates, precursor gases, and outsourced processes.
