Job summary

N/A is seeking a qualified Process Engineer to develop, validate, and optimize optical manufacturing processes in a controlled cleanroom environment. You will lead transfer and scale-up for mass production of optical fibers and precision assemblies, ensuring cleanliness, quality, and cost targets.

Requirements include a degree in optical/mechanical discipline and 3+ years in similar settings, with hands-on experience in Lean Six Sigma, DOE, FMEA, and SPC.

Qualifications

• Bachelor’s or Master’s degree in Optical Engineering, Materials Science, Mechanical/Precision Engineering, Physics, or Chemistry.
• 3+ years of experience in a manufacturing or engineering environment, preferably optical/laser/cleanroom.
• Hands-on process development, NPI, and manufacturing scale-up experience.
• Proven Lean Six Sigma tools (DOE, 8D, FMEA, SPC).
• Experience in cleanroom or high-precision manufacturing environments is highly preferred.
• Knowledge of optical fiber assembly, laser systems, or precision contamination control is an advantage.
• Experience with ISO 9001, ISO 14001, or AS9100 quality systems.
• Strong problem-solving and root cause analysis abilities.
• Exposure to customer-facing technical discussions or escalation handling.
• Familiar with AutoCAD or SolidWorks is an advantage.
• Experience with ERP systems (e.g., SAP) is a plus.
• Strong communication, teamwork, and stakeholder management skills.
• Continuous improvement mindset with a passion for operational excellence.

Responsibilities

• Develop, validate, and optimize processes for fiber optic termination and polishing.
• Design and implement ultra-clean assembly workflows in a controlled semiconductor cleanroom environment.
• Lead transfer and development of new manufacturing processes for mass production of optical fiber assemblies and precision products.
• Define and implement cleanliness and process specifications to ensure stable and compliant production conditions.
• Drive continuous improvement initiatives to enhance productivity, efficiency, quality, and cost performance.
• Support Design for Manufacturability (DFM) and New Product Introduction (NPI) activities to ensure smooth product launch and scale-up.
• Collaborate closely with project teams to ensure timely execution of technical projects, meeting cost, quality, and delivery targets.
• Lead process validation, risk assessments (FMEA), and tooling development for new production lines.
• Implement process controls and problem-solving methodologies (SPC, 8D, DOE) to resolve technical issues and improve yield.
• Drive customer communication during technical escalations and provide timely progress updates to stakeholders.
• Ensure safety compliance, including laser safety assessments, and promote a strong safety culture in the workplace.
• Support training and development of technicians and production teams to build strong operational capability.
• Participate in supplier/source qualification and ensure readiness for production transfer and handover.
