Optical Module Coupling Engineer

About the role

Cisco's Process & Automation team in Bangkok is looking for an Optical Module Coupling Engineer to join its manufacturing technical team. The role works cross-functionally with process engineering, manufacturing, equipment and quality teams to drive productivity, yield and quality improvements through advanced automation technologies. It focuses on optical coupling process development, mass production implementation, process optimization and technical troubleshooting.

Key responsibilities

• Carry out daily optical coupling production work for various optical modules.
• Optimize existing optical coupling processes to improve coupling efficiency, product yield and consistency, and reduce production costs and defect rates.
• Provide on-site technical support for coupling production, responding quickly to abnormal production conditions and handling process and product defects.
• Analyze failure causes of defective products (e.g., coupling offset, optical power loss, glue failure, fiber displacement) and define improvement and preventive measures.
• Work with R&D and quality teams to verify new products, processes and materials, and complete process validation and mass production conversion.
• Maintain coupling process documents, SOPs and failure analysis reports, building technical archives.

Required profile

• Bachelor's degree or above in Optics, Optoelectronics, Electronic Engineering, Mechanical Engineering or a related major.
• Familiarity with basic optical theory, optical module operation, optical path transmission and fiber coupling mechanisms.
• Hands-on experience in optical module coupling, including coupling equipment operation, fiber alignment adjustment and optical power calibration.
• Independent failure analysis and problem-solving skills, with good logical thinking and on-site emergency response.
• Preferred: rich experience in high-speed optical module coupling and mass production optimization, and experience leading process improvement projects.

Required skills

• Knowledge of common optical module products (SFP, QSFP, OSFP, 800G/400G) and mainstream coupling processes is preferred.
• Preferred familiarity with optical testing instruments such as optical power meters, spectrum analyzers and insertion loss testers.
