Process Engineer

Primary Duties & Responsibilities

1. Process Development & Optimization
   • Develop and optimize chemical-mechanical polishing (CMP) and fine grinding processes for silicon optics.
   • Establish and control critical process parameters including abrasive selection, pressure, speed, slurry composition, pH control, and temperature.
   • Define process windows to ensure repeatability, yield, and optical surface quality.
   • Reduce defects such as surface haze, scratches, subsurface damage, and surface roughness through structured process improvements.
   • Support process transfer from development or pilot builds into volume manufacturing.
2. Tooling & Equipment Management
   • Design, evaluate, and improve tooling, fixtures, pads, and workholding systems for silicon optics fabrication.
   • Lead equipment qualification, acceptance, and process validation activities (IQ/OQ/PQ).
