Advanced Processing Cleaning & Contamination Engineer

ASML brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world's leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics. Our main headquarters are located in Veldhoven, the Netherlands, and we also have 18 office locations around the United States- including main offices in Wilton, CT, Chandler, AZ, San Jose, CA and San Diego, CA.

As an Advanced Processing Cleaning & Contamination Engineer, you will directly support our mission to enable the world's most advanced chip manufacturing. You will be a subject-matter expert in precision cleaning, contamination mitigation, and optical cleanliness standards.

In this role, you will work in a dynamic, collaborative environment supporting production teams, development groups, and cross-functional engineering partners to create clean, stable, and highly reliable processes.

Role Overview

The Advanced Processing Cleaning & Contamination Engineer will develop and industrialize precision cleaning processes, reduce particle/molecular contamination risks, and drive continuous improvement for highvalue optical components. You will lead equipment introductions, support contamination test systems, and ensure robust, repeatable cleaning performance in a fastpaced, hightech manufacturing environment.

• Master's degree with 2+ years of relevant experience, or Bachelor's degree with 6+ years of relevant experience in Chemical Engineering, Materials Science, Mechanical Engineering, or related fields.
• Experience in lithography, precision optics, contamination control, surface science, or semiconductor manufacturing highly preferred.
• Strong understanding of chemical cleaning media, material compatibility, reaction mechanisms, and precision cleaning science.
• Experience with automated or semiautomated cleaning processes for optical components (direct or indirect).
• Experience with manual cleaning processes for optical components.
• Experience with FMEA, control plans, 4C, DMAIC, 8D, or other structured problem-solving frameworks.
• Background in surface science, contamination physics, or thinfilm materials.
• Experience supporting laboratory environments, calibration processes, or metrology equipment.

Competencies

• Communicate clearly across engineering, operations, and crossfunctional teams.
• Analyze data effectively and identify trends using structured problemsolving methods.
• Work proactively and adapt quickly in a fastpaced environment.
• Solve technical problems with curiosity, attention to detail, and a systematic approach.
• Organize work logically and manage multiple priorities simultaneously.
• Follow procedures carefully to maintain a clean, controlled environment.
• Contribute ideas that reduce contamination risk, improve processes, and support continuous improvement.
• Build strong working relationships and support a collaborative team culture.

Additional Skills

• Proficiency with Python, MATLAB, or similar tools for data analysis or automation.
• Experience with SPC, JMP, Minitab, or similar statistical analysis tools.
• Strong skills in Microsoft Office (Excel, PowerPoint, Word).
