Advanced Processing Cleaning & Contamination Engineer

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.

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

• Develop a deep understanding of precision optical cleaning requirements across all relevant departments.
• Evaluate, develop, and optimize chemical and ultrasonic cleaning methods for sensitive optical components.
• Identify common contaminants and implement effective removal strategies.
• Support and improve semiconductor‑grade cleaning technologies and cleanliness standards.
• Support contamination test systems, maintaining procedures, settings, and process improvements.
• Troubleshoot contamination‑related issues and provide support during escalations.
• Analyze process and test data to identify trends, stabilize operations, and reduce variation.
• Contribute to process improvements that enhance productivity and reduce defects.

• Generate high‑quality technical documentation such as engineering test plans, work instructions, equipment specifications, and qualification reports.
• Maintain documentation for contamination testing, lab processes, and cleaning systems.
• Apply Job Safety Analysis principles and collaborate with EHS to ensure safety and compliance.

• Lead new equipment projects from specification and vendor engagement through procurement, FAT/SAT, installation, and internal qualification.
• Assist with laboratory activities and support equipment maintenance and calibration.
• Support new product introduction (NPI) through qualification activities and documentation updates.

• Collaborate with engineering, operations, and lab teams to maintain stable processes and support daily production needs.
• Support KPI tracking, reporting, and data‑driven decision making.
• Engage with cross‑functional groups during escalations to diagnose and resolve contamination issues.

• 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 semi‑automated 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 thin‑film materials.
• Experience supporting laboratory environments, calibration processes, or metrology equipment.

• Communicate clearly across engineering, operations, and cross‑functional teams.
• Analyze data effectively and identify trends using structured problem‑solving methods.
• Work proactively and adapt quickly in a fast‑paced 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,…
