Plan execute and analyze structured process experiments and DOE; translate results into controlled work instructions recipes process specifications and training materials.

Investigate growth material and equipment excursions using data and root-cause methods; define and verify corrective and preventive actions with Manufacturing Quality Maintenance and Engineering partners.

Use process and characterization data to identify trends in defects inclusions stress cracking composition optical performance and other relevant material attributes; recommend practical process improvements.

Support furnace and ancillary-equipment capability including preventive maintenance priorities calibration controls sensors vacuum or inert-gas systems RF or induction systems and troubleshooting of equipment-related variation.

Establish and maintain process-control plans risk assessments change-control records and technical reports; communicate results risks and recommendations clearly to cross-functional teams and leadership.

Support transfer of new or improved processes from development to production including qualification runs acceptance criteria operator training and sustained process monitoring.

Promote a strong EHS culture by following applicable procedures and identifying hazards associated with high temperature vacuum pressure inert gases RF/induction power and materials handling.
