Cleanliness Expert – Ultra‑Clean High‑Tech Systems

About this vacancy

The Mission

As a Cleanliness Expert, you will ensure that our systems meet the most extreme cleanliness standards in the industry down to grade 1 levels. You understand how factors like cutting oils, cooling fluids, and microscopic production residues influence system performance. You know how to prevent contamination at every step of the supply chain, and you translate that expertise into clear specifications, validation methods, and robust processes. Your work directly safeguards the functionality, lifetime, and stability of high‑tech systems used worldwide.

Your Role

In this role, you will define, validate, and enforce contamination‑control requirements across complex modules and systems. You will:

• Specify cleanliness requirements to ensure functional and ultra‑clean system performance.
• Participate in design reviews to embed contamination‑control measures from the start.
• Lead functional qualification activities, with emphasis on surface analysis and photochemistry.
• Own root‑cause analyses for contamination‑related issues and propose effective solutions.
• Develop and maintain contamination‑control design rules for next‑generation systems.
• Generate new ideas that advance the organization’s cleanliness capabilities.
• Document specifications, calculations, and test data with precision and clarity.
• Provide methods, tools, and verification techniques to validate cleanliness requirements.
• Detect, mimic, and control contamination designing tools when needed.
