Senior Fab Quality Manager - InP Photonics

Location: Alhambra, CA (Onsite)

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.

Minimum Qualifications:

• Master's Degree in Electrical/Electronic Engineering, Applied Physics, Materials Science, Optical Engineering or related degree. PhD is a plus.
• Solid knowledge of III-V semiconductor device physics with emphasis on InP-based photonic devices including edge-emitting lasers, VCSELs, SOAs, and modulators.
• Deep understanding of InP epitaxial growth processes (MOCVD/MBE), including material quality assessment, layer structure optimization, and defect management.
• Solid knowledge of wafer fabrication processes specific to III-V compounds including dry/wet etching, metallization, passivation, cleaving, and AR/HR coating technologies.
• 7+ years of demonstrated experience in quality engineering, product engineering, or process engineering within III-V semiconductor or photonics manufacturing environment.
