Process Engineer

Primary Duties & Responsibilities

1. Process Development & Optimization

• Develop and optimize chemical-mechanical polishing and fine grinding techniques for ZnSe.
• Establish process parameters (abrasive selection, pressure, speed, slurry composition, pH control, temperature).
• Reduce defects such as surface haze, scratches, subsurface damage, and roughness through process improvements.

2. Production & Quality Control

• Implement statistical process control (SPC) for polishing uniformity.
• Define quality criteria (flatness, roughness, surface irregularities) based on interferometry.
• Work with the Quality Assurance team to ensure compliance with optical performance standards (ISO 10110, MIL-PRF-13830B).

3. Tooling & Equipment Management

• Maintain and optimize lapping and polishing equipment (single/double-sided polishers, planetary systems).
• Evaluate new tools, p...
