Job description

Position Overview

The incumbent supports the development and manufacturing of Optical Interposer products by improving yield and performance. The role focuses on data-driven defect analysis, root-cause resolution, and collaboration with internal teams and fabrication partners to ensure high-quality, reliable, and manufacturable optical engine designs.

Responsibilities

• Design and develop Optical Interposer products with a focus on yield and performance optimization.

• Lead yield improvement and defect reduction initiatives across optical engine designs.

• Conduct data analysis, problem characterization, and root-cause fault isolation for yield-related issues using commonality analysis, regression analysis, and systematic DMAIC problem-solving approaches.

• Define and document failure modes, material impact, and fallout percentages to support corrective actions.

• Monitor, track, organize, and present yield data from fabrication partners.

• Implement checklists, guidelines, and "lessons learned" documentation to support ongoing yield-improvement activities.

• Perform yield correlation and failure-analysis work (electrical, optical, physical) and support additional engineering tasks as assigned.

Qualifications & Requirements

• Education & Experience: Bachelor's or Master's degree with at least 5 years of experience in a process integration role, specializing in yield improvement, preferably in optoelectronics or semiconductor manufacturing.

• Technical Expertise: Strong foundation in semiconductor physics and engineering fundamentals, with a good understanding of mechanical, electrical, and thermal failure mechanisms. Proficiency in statistical analysis tools (e.g., JMP) and experience with commonality analysis, regression analysis, or systematic DMAIC problem-solving approaches. Experience with Python programming for engineering data analysis and automation is an added advantage.

• Yield Enhancement & Certification: Experience in yield enhancement, defect reduction, or process improvement roles is preferred. Lean Six Sigma certification is an added advantage.
