II-VI UK, Ltd.; Sherman (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Coherent Corp. is a global leader in lasers and photonics, seeking a Product Engineer to lead yield improvements in a 24/7 manufacturing environment in Sherman, TX.

You will own yield bridge activities for NPI and high-volume ramp, coordinating cross-functional teams to troubleshoot and resolve excursions with CAPA and data-driven methods. The role requires a postgraduate degree in engineering or physics, 10+ years in optoelectronics, and strong statistical analysis skills with JMP or Minitab.

Qualifications

• Master's or PhD in electrical engineering, physics, materials science, or related field.
• 10+ years professional experience in semiconductor/optoelectronics.
• Hands-on design, processing, and characterization of VCSELs, DFB lasers, or photonic integrated chips.
• Proficiency with JMP, Minitab, or similar statistical tools.
• Experience in high-volume manufacturing and wafer fab operations.
• Excellent cross-functional leadership and communication.

Responsibilities

• Monitor and improve yield performance across the entire manufacturing flow, including wafer fabrication, electrical and optical testing, and reliability evaluations.
• Lead cross-functional teams to investigate yield excursions, identify root causes, and implement CAPA measures promptly.
• Support daily production by resolving issues and analyzing failures on the wafer fabrication and testing line.
• Collaborate with R&D to introduce new optoelectronic chips for 3D sensing applications.
• Conduct design and process sensitivity studies to define EPI/process spec limits and enhance manufacturability.
• Lead production ramp-up readiness with cross-functional teams on chip design, equipment, process flow, and documentation.
• Drive yield improvement and cost reduction post-production ramp, employing statistical analysis to troubleshoot yield deviations.
• Work with optical sub-assembly and transceiver module teams to address chip-related performance issues at contract manufacturers.
• Own yield bridge activities during new product introduction and the transition to high-volume manufacturing.
