• Ensure strict compliance with SOPs, process controls, ESD, safety, and cleanroom standards during all production activities.
• Collaborate with Process Engineering (PE), Quality Engineering (QE), and Equipment teams to resolve production issues, process deviations, or equipment downtime.
• Support NPI and engineering builds by coordinating manpower, training operators, and ensuring process readiness.
• Conduct real-time line audits, quality checks, and operator performance observations to prevent quality escapes.
• Provide coaching, training, and skill development for operators to improve competency, productivity, and flexibility.
• Maintain shift documentation including production reports, attendance, incident logs, and abnormality reports.
• Drive 5S, Kaizen, cost reduction, and continuous improvement initiatives in the production area.
• Ensure proper material, tooling, and fixture readiness by coordinating with Warehouse, Planning, and Engineering teams.
• Participate in daily/weekly production meetings and communicate shift performance, issues, and recovery plans.
• Escalate critical issues promptly and coordinate corrective actions to minimize production impact.
• Perform additional responsibilities or tasks assigned by the Manager.

Qualifications

• Bachelor’s degree in Engineering, Industrial Technology, Manufacturing, Science, or a related field (Diploma/Vocational + strong experience may also be considered).
• 3–8 years of experience in high-tech, electronics, semiconductor, optical, or precision manufacturing.
• Minimum 2+ years in a leadership or supervisory role managing production teams.
• Strong understanding of manufacturing processes, WIP control, quality standards, and production metrics.
• Experience working in cleanroom, optical, or high-precision environments is an advantage.
• Strong leadership, communication, and coaching skills with the ability to guide and motivate teams.
• Ability to work rotating shifts and support fast-paced, high-volume production environments.
• Problem-solving mindset with the ability to analyze issues, drive root cause containment, and implement improvements.
