Job Description/Preferred Qualifications
Position Summary
We are seeking a highly motivated Mechanical / Opto-Mechanical Engineer to lead initiatives focused on energy reduction and purge gas optimization across advanced semiconductor equipment platforms.
This role will combine physics-based modeling, optical/mechanical system design, and experimental validation to reduce energy consumption and minimize use of high-cost and high-impact purge gases (e.g., N₂, CDA, specialty gases).
The ideal candidate will bridge optical systems, fluid dynamics, thermal management, and mechanical design to develop innovative solutions that improve tool efficiency while maintaining or enhancing performance, reliability, and contamination control.
