Senior Specialist Line Control

Your Role

Key responsibilities in your new role

To maximize factory throughput and deliver orders on time while keeping inventory levels as low as possible, including;

• Daily Scheduling: Translating monthly customer demand forecasts into actionable daily and weekly production schedules.
• Lot Release (WIP Injection): Calculating and releasing the exact number of production lots (or wafers/chips) into the line to prevent bottlenecks.
• Material Readiness: Verifying that all raw materials, lead frames, substrates, and components are physically available before starting a run.
• WIP Flow Management: Monitoring Work-In-Progress (WIP) levels across different manufacturing stations (e.g., Die Attach, Wire Bond, Testing)to ensure smooth product movement.
• Bottleneck Mitigation: Identifying equipment constraints or sudden machine breakdowns, and dynamically rerouting production lots to alternative lines.
• "Hot Lot" Management: Fast-tracking urgent customer orders or engineering engineering samples through the factory without disrupting the standard production flow.
• Cycle Time Tracking: Monitoring the actual time it takes for a product to go from start to finish, ensuring it meets target cycle times.
• On-Time Delivery (OTD): Ensuring the factory meets its commitments to global distribution centers and clients.
• Inventory Control: Managing and minimizing aging WIP, slow-moving stock, and excess inventory sitting on the shop floor.
• Engineering Alignment: Coordinating with maintenance and equipment engineers to schedule planned preventive maintenance (PM) during low-impact windows.
• Supervisor Collaboration: Partnering with Production Supervisors to ensure the shop floor operators are executing the schedule according to the day's true priorities.
• Global Supply Chain Sync: Interfacing with regional supply chain hubs (e.g., Singapore) to report on capacity constraints, yield losses, or output delays

Your Profile

Qualifications and skills to help you succeed

• Degree: Bachelor’s degree in Industrial Engineering, Supply Chain Management, Operations Research, or Business Administration.
• Experience Level: Senior/Staff Specialists (5+ years) handling complex multi-site constraints.
• Data Proficiency: Mastery of Advanced Excel (Macros, VLOOKUP, pivot tables) and data analysis tools to track performance variances.
• Systems Architecture: Direct experience navigating ERP systems (SAP) and computerized Manufacturing Execution Systems (MES) to map material movements and release production lots.
• Dynamic Scheduling: Developing and executing production master schedules based on volatile demand forecasts while keeping Work-In-Progress (WIP)levels lean.
• Bottleneck Resolution: Constant calculation of machine capacity limitations, cycle times, and equipment availability to maximize factory utilization.
• Inventory & Shortage Mitigation: Monitoring buffer stocks, tracking raw materials/wafer arrivals, and coordinating with procurement to eliminate line-stoppage risks.
• Lean Methodologies: Applied understanding of Pull Systems, Kanban, and Just-In-Time (JIT) principles to streamline shopfloor workflows.
• English: Strong professional command (written and verbal). The planner interacts heavily with ERP systems, global supply chain planning hubs and generates English-language utilization reports.
• Thai: Fluent/Native to quickly coordinate with local shopfloor leads and engineering staff regarding physical material status.
