Job Summary
We are seeking a highly experienced engineer with a strong foundation in chemistry to lead contamination control and manufacturing process development for deep-ultraviolet (DUV) laser systems. This role requires deep expertise in photochemistry, surface chemistry, and contamination mechanisms that impact the performance, reliability, and lifetime of DUV optical systems. The ideal candidate will have hands-on experience diagnosing and mitigating chemically driven degradation in high-energy UV environments.
This is a technically demanding role with significant influence on materials selection, manufacturing process development, and long-term system reliability.
Key Responsibilities
- Lead and advance contamination control strategies for DUV laser manufacturing
- Analyze and mitigate photochemical and surface-driven degradation mechanisms affecting optics, coatings, crystals, and surrounding materials
- Evaluate and select materials, including polymers, metals, adhesives, coatings, solvents, and cleaning agents for compatibility with deep-UV exposure
- Develop and qualify cleaning, passivation, and handling processes based on chemical and surface-science principles
- Lead root-cause analysis of DUV-induced failures and contamination-related issues
- Model and experimentally validate contamination transport, adsorption/desorption, and photo-induced reactions in DUV environments
- Collaborate closely with R&D teams to translate laboratory-scale DUV solutions into robust manufacturing processes
- Define contamination-control specifications, cleanliness requirements, and acceptance criteria
- Support supplier qualification, engagement, and audits related to chemical cleanliness and material compatibility
- Mentor junior engineers and serve as a subject-matter expert in DUV contamination control and chemistry
