• Proficiency in thin film design software such as:
• FILMSTAR, OptiLayer, TFCalc, or equivalent
• Familiarity with:
• Statistical Process Control (SPC)
• Six Sigma / Lean manufacturing principles
• Strong analytical, problem-solving, and documentation skills
• Ability to work independently in a fast-paced, production-driven environment
• Strong collaboration and interpersonal skills
• Proficiency in Microsoft Office (Excel, Word, PowerPoint)
• Demonstrated ability to lead cross-functional improvement initiatives

What You'll Do

• Develop and optimize optical thin film coating designs to meet product performance specifications
• Support new product introduction (NPI) by transferring coating processes from R&D to manufacturing
• Operate, troubleshoot, and improve PVD and vacuum coating systems
• Design and implement experiments to improve coating performance, yield, and reliability
• Analyze process data using SPC tools and drive continuous improvement initiatives
• Collaborate with R&D, production, quality, and engineering teams to resolve technical issues
• Lead root cause analysis and implement corrective/preventive actions for process deviations
• Develop and maintain technical documentation, process instructions, and work standards
• Support scaling of coating processes for high-volume manufacturing
• Train technicians and operators on coating processes and best practices
• Partner with cross-functional teams to improve yield, cost efficiency, and process capability
• Contribute to the adoption of Lean / Six Sigma methodologies in process improvement
• Support equipment qualification, maintenance strategies, and process validation activities

What We're Looking For

• A hands-on thin film coating engineer with strong manufacturing and process experience
• Proven ability to translate optical coating designs into scalable production processes
• Strong technical problem-solver with a structured, data-driven mindset
• Comfortable working across R&D and production environments
• A proactive, collaborative team player who thrives in a fast-paced, innovation-driven setting
