Advanced Processing Coating Process Engineer

• Develop a deep understanding of optical thin‑film requirements, including reflectivity, transmission, uniformity, stress, adhesion, and cosmetic performance
• Develop, optimize, and sustain optical coating processes using physical vapor deposition (PVD) techniques such as electron beam evaporation, sputtering, and ion‑assisted deposition
• Own process recipes, control parameters, and process windows to ensure stable and repeatable coating performance
• Troubleshoot coating‑related issues including optical performance shifts, defects, adhesion failures, and cosmetic non‑conformances
• Analyze process, metrology, and test data to identify trends, reduce variation, and improve yield and throughput
• Support day‑to‑day production needs, including process certification, escalations, technician training & certification, and root cause investigations
• Drive continuous improvement initiatives to enhance coating performance, productivity, and equipment utilization
• Generate high‑quality technical documentation including engineering test plans, qualification reports, work instructions, and process specifications
• Maintain coating process documentation, OCAPs, and change control records
• Apply structured problem‑solving methodologies (e.g., FMEA, 8D, DMAIC) to improve process robustness
• Collaborate with EHS and operations teams to ensure safe operation of coating systems and compliance with environmental and safety requirements
• Lead coating equipment projects from concept through vendor engagement, specification, FAT/SAT, installation, and internal qualification
• Support equipment troubleshooting, maintenance planning, and process capability improvements in collaboration with equipment engineering
• Support new product introduction (NPI) through coating process development, qualification, and release to production
• Participate in capital planning, equipment road‑mapping, and technology upgrades
• Collaborate closely with production, inspection, cleaning, equipment engineering, and design teams to ensure end‑to‑end process success
• Support KPI tracking and data‑driven decision making related to yield, quality, and availability
• Communicate clearly during escalations and lead cross‑functional efforts to resolve coating performance issues

• Master’s degree with 1+ years of relevant experience, or Bachelor’s degree with 3+ years of relevant experience in Materials Science, Physics, Optical Engineering, Chemical Engineering, Mechanical Engineering, or related fields
• Experience in optical thin‑film coating, precision optics, or semiconductor manufacturing strongly preferred
• Strong understanding of thin‑film optics, optical constants, interference coatings, and material properties
• Hands‑on experience with PVD coating systems (e‑beam, sputtering, IAD, or similar)
• Experience with coating qualification, process transfer, and production support
• Experience using structured problem‑solving frameworks such as FMEA, 4C, A3, or 8D
• Proficiency with Python, MATLAB, or similar tools for data analysis, modeling, or automation
• Experience with SPC, JMP, Minitab, or similar statistical analysis tools
• Strong skills in Microsoft Office (Excel, PowerPoint, Word)

Familiarity with optical metrology techniques (e.g., spectrophotometry, ellipsometry, surface inspection) is a plus
