Assembly Process Engineer, Senior

We are seeking a highly motivated Senior Assembly Process Engineer to lead the development, validation, optimization, and scale-up of advanced manufacturing processes for optical fiber assemblies, precision components, and photonics products. This role is critical in driving New Product Introduction (NPI), process innovation, manufacturing excellence, and continuous improvement within a semiconductor cleanroom and high-precision manufacturing environment.

The ideal candidate will possess strong expertise in process engineering, fiber optic assembly, cleanroom manufacturing, Lean Six Sigma methodologies, and production scale-up, with a passion for delivering high-quality, cost-effective, and reliable manufacturing solutions.

What You'll Do

• Develop, validate, and optimize fiber optic assembly, termination, and polishing processes to achieve high product quality, yield, and manufacturability.
• Design and implement ultra-clean assembly workflows in semiconductor cleanroom environments.
• Lead process development, technology transfer, and production scale-up for new optical and precision products.
• Drive New Product Introduction (NPI) activities and support Design for Manufacturability (DFM) initiatives.
• Establish process specifications, cleanliness standards, and manufacturing controls to ensure consistent production performance.
• Lead process validation, equipment qualification, risk assessments, and tooling development activities.
• Identify and implement continuous improvement opportunities to enhance productivity, quality, yield, and cost efficiency.
• Apply Lean Six Sigma methodologies including DOE, SPC, FMEA, 8D, and Root Cause Analysis to solve manufacturing challenges.
• Collaborate with cross-functional teams including R&D, Quality, Operations, Supply Chain, and Engineering to meet project objectives.
• Support customer technical discussions, issue resolution, and escalation management.
• Train and mentor technicians and production personnel on manufacturing processes and best practices.
• Ensure compliance with safety, quality, and environmental standards, including laser safety and cleanroom protocols.
• Support supplier qualification, process transfer, and manufacturing readiness activities.

What You'll Need

• Bachelor's or Master's degree in Optical Engineering, Photonics, Mechanical Engineering, Materials Science, Physics, Chemistry, Precision Engineering, or a related technical discipline.
• 3+ years of experience in manufacturing, process engineering, or production engineering within optical, photonics, semiconductor, laser, or precision manufacturing environments.
• Hands-on experience with process development, NPI, manufacturing scale-up, and process validation.
• Strong knowledge of Lean Six Sigma tools and methodologies including DOE, SPC, FMEA, 8D, and Root Cause Analysis.
• Experience working in cleanroom, semiconductor, or other highly controlled manufacturing environments.
• Strong troubleshooting and problem-solving skills with a data-driven approach to decision-making.
• Excellent communication and collaboration skills with the ability to work effectively across multidisciplinary teams.
• Ability to manage multiple projects while balancing quality, cost, and delivery objectives.

Preferred Qualifications

• Experience with optical fiber assembly, fiber termination, polishing processes, or photonics manufacturing.
• Knowledge of laser systems, optical products, and contamination control techniques.
• Familiarity with ISO 9001, ISO 14001, AS9100, or similar quality management systems.
• Experience using AutoCAD, SolidWorks, or other CAD software.
• Exposure to ERP systems such as SAP.
• Experience supporting customer-facing technical discussions and manufacturing transfers.
