• Establish process windows, critical process parameters, and statistical process controls for surface treatments.
• Design and execute statistically rigorous experiments (DOE) to understand process interactions and optimize surface performance.
• Characterize processed surfaces using techniques such as ellipsometry, contact angle, AFM, optical microscopy, fluorescence imaging, profilometry, XPS, SEM, and related analytical methods.
• Translate laboratory processes into scalable manufacturing methods with high yield and reproducibility.
• Drive equipment selection, installation, qualification, and process transfer to manufacturing.
• Mentor junior scientists and engineers while fostering rigorous experimental design, scientific curiosity, and rapid technical iteration.

Qualifications

Required

• M.S. (+8 years of relevant industrial experience) or Ph.D. (+ 4 years) in Mechanical Engineering, Chemistry, Chemical Engineering, Materials Science, Biomedical Engineering, or a related discipline.
• Demonstrated expertise in surface processing and process development.
• Experience developing manufacturing-ready surface processes with an emphasis on spatial uniformity, repeatability, process capability, and yield.
• Experience selecting, operating, qualifying, and troubleshooting process equipment.
• Experience with statistical experimental design (DOE), process optimization, and statistical analysis tools (JMP, Python, R, etc.).
• Experience using surface characterization techniques including ellipsometry, contact angle, AFM, profilometry, fluorescence microscopy, SEM, XPS, or related methods.
• Strong written and verbal communication skills.
• Comfortable working in a fast-moving, highly collaborative environment.
• Hands-on willingness to develop and troubleshoot processes in the laboratory.

Experience in one or more of the following:

• Coating methods including spin coating and dunk coating
• Plasma cleaning equipment
• Chemical mechanical polishing (CMP), surface planarization
• Vapor-phase surface deposition processes and equipment
• Wet chemical cleaning and substrate preparation
• Strong understanding of process development for glass, silicon, metal oxide, and other semiconductor-related materials.

Preferred
