Process Engineer

Job Summary: The Process Engineer is responsible for developing, industrializing, and optimizing silicon optics fabrication processes to support production ramp-up and stable high-volume manufacturing. This role focuses on chemical‑mechanical polishing (CMP), fine grinding, tooling, defect reduction, and process efficiency in a precision manufacturing environment.

Primary Duties & Responsibilities:

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.
