We are seeking a Senior Manufacturing Engineer who will be responsible for driving process performance and improvement for a designated product line. This role ensures stable daily operations, leads yield‑improvement initiatives, and supports technology introduction activities to enhance long‑term manufacturing capability.

• Lead end‑to‑end manufacturing process performance for the assigned product line, ensuring stable operations, output consistency, and continuous improvement.
• Monitor key process indicators, analyze trends, and initiate improvement actions to enhance yield, reduce variation, and strengthen process robustness.
• Drive structured investigations for complex or recurring issues using engineering tools such as SPC, DOE, 8D, FMEA, and root‑cause analysis methodologies.
• Identify and implement optimization opportunities to improve process capability, cost efficiency, and long‑term manufacturability.
• Execute engineering qualifications for new equipment, materials, and process changes, ensuring thorough evaluation and successful integration into production.
• Prepare, update, and maintain process documentation including specifications, work instructions, FMEA, OCAP, and technical reports.
• Assess material behavior, process interactions, and performance impact using relevant analytical techniques and engineering data.
• Collaborate closely with Production, Equipment, Quality, and Development teams to support process enhancements, capability upgrades, and product performance improvements.
• Support development activities by contributing technical input to wafer process development initiatives and assisting with the introduction and industrialization of new technologies.
• Lead cross‑functional discussions and drive sustainable corrective and preventive actions for process or quality issues.
• Provide technical guidance, coaching, and competency assessments for technicians and operators to ensure adherence to process requirements.
• Ensure compliance with applicable quality, environmental, health, and safety standards within the area of responsibility.

• Bachelor’s or Master’s degree in Physics, Physics Engineering, Materials Science, or Advanced Engineering Materials.
• Minimum 3–5 years of relevant experience in semiconductor wafer fabrication is preferred. Fresh Master’s graduates with strong research or laboratory experience are also encouraged to apply.
• Hands‑on experience in process engineering, yield improvement, and data analysis.
• Familiarity with SPC, DOE, FMEA, Lean Six Sigma, and structured problem‑solving methodologies.
• Experience collaborating with development or new product introduction teams is an advantage.
• Understanding of material analysis techniques, including physical (PSA‑Micro, PSA‑Nano, hardness), composition (EDS, X‑ray, FTIR), structural and morphological (SEM, FE‑SEM, 3D Optical Microscope), and thermal methods (TGA, DSC).
• Strong analytical thinking, problem‑solving capability, and ability to lead cross‑functional investigations.
• Good communication skills with the ability to work effectively with production, quality, and development teams.
• Proactive, structured, and data‑driven approach with strong ownership and follow‑through.
• Fluent in English, both written and spoken.
