• Applying optical engineering, imaging, and machine vision principles to develop robust methods using transmitted light, reflected light, bright field, dark field, polarization, structured illumination, and other contrast mechanisms as appropriate.
• Developing image acquisition, analysis, and data interpretation workflows to improve defect detection sensitivity, repeatability, and overall method capability.
• Partnering closely with R&D, process development, product development, quality, manufacturing, and equipment teams to define inspection requirements and translate technical needs into scalable solutions.
• Supporting the transfer of inspection methods from laboratory concept through pilot evaluation and into manufacturing implementation.
• Specifying and supporting production inspection equipment and contributing technical expertise to capital equipment projects.
• Designing experiments, analyzing data, and conducting method validation activities, including measurement systems analysis, gauge capability, and robustness studies.
• Creating technical documentation, operating procedures, specifications, and reports to support development, qualification, and deployment of inspection methods.
• Supporting troubleshooting and root cause analysis related to quality, defect generation, and inspection performance.
• Contributing to a culture of technical rigor, collaboration, and continuous improvement while working within applicable quality system requirements.
