Coherent Corp. Vietnam•Fremont, CA

1d•$82,000 - $135,063•Hybrid

About The Position

Coherent is a global leader in lasers, engineered materials and networking components. We are a vertically integrated manufacturing company that develops innovative products for diversified applications in the industrial, optical communications, military, life sciences, semiconductor equipment, and consumer markets. Coherent provides a comprehensive career development platform within an environment that challenges employees to perform at their best, while rewarding excellence and hard-work through a competitive compensation program. It's an exciting opportunity to work for a company that offers stability, longevity and growth. Come Join Us! This role involves analyzing datasets generated by wafer fabrication processes, equipment, sensors, metrology systems, and manufacturing execution systems. The candidate will support multiple projects, drive detailed data analysis using various ML/AI tools, and apply statistical analysis, AI, machine learning, and data-mining techniques for deeper understanding of devices and fabrication processes, process monitoring and anomaly detection, wafer and lot excursion analysis, yield analysis and prediction, and root-cause investigation. The role also includes collaborating with others using AI & ML, integrating data from multiple sources, translating analytical results into clear engineering insights and actionable recommendations, communicating findings to engineers and managers, and working with engineers to distinguish correlation from likely physical or process-driven causation. Additionally, the position involves developing reusable data pipelines, analytical tools, dashboards, and model-monitoring methods, supporting design of experiments, process characterization, and continuous improvement activities, and helping establish best practices for data quality, feature engineering, model validation, documentation, and responsible use of AI in development and manufacturing.
