Yield Engineer – Optoelectronic Device Manufacturing

Primary Duties & Responsibilities

• Yield Monitoring & Analysis:
  • Track yield performance across production lines and quickly identify negative trends.
  • Use structured problem-solving techniques to investigate and resolve yield excursions.
• Data Mining & Analytics:
  • Perform deep dives into large manufacturing datasets using SQL, JMP, and other data analysis tools.
  • Build and maintain predictive yield models and apply machine learning techniques for early detection of defects or deviations.
• Process & Device Expertise:
  • Leverage a strong understanding of semiconductor process flows and device physics for optoelectronic components.
  • Collaborate with process engineers to refine process windows and reduce variability.
• Cross-Functional Collaboration:
  • Work closely with R&D, Manufacturing, Process Engineering, Equipment Engineering and Quality teams to coordinate efforts and communicate results.
  • Lead cross-functional teams during yield improvement and cost reduction initiatives.
• Customer Engagement:
  • Serve as a technical liaison with key customers to present yield updates, address concerns, and support audits or joint improvement projects.
• New Product Introduction (NPI):
  • Support rapid ramp-up of new optoelectronic products, ensuring smooth transitions from development to production with high initial yields.
  • Conduct risk assessments and drive DFM (Design for Manufacturability) recommendations.

Education & Experience

• Bachelor’s or Master’s degree in Electrical Engineering, Materials Science, Applied Physics, Data Science, or a related field.
