MRP Execution

Key Responsibility

Order & Customer Commitment

• Provide commit delivery dates for every customer order (Order promising / ATP).
• Track and improve CLIP/Customer Line Item Performance for all customers.
• Manage re-commits when customer requests change (product change, hold, release, expedite, slow-down).
• Coordinate with Customer Ops for WIP visibility, priority lots, and shipment planning.
  
  

Daily Wafer Start & Production Scheduling

• Prepare daily wafer start plan across technology nodes and products.
• Execute wafer start for each order/production lot based on capacity and loading targets.
• Drive start stability, weekly loading adherence, and cycle time compliance.
• Align with diffusion, litho, etch, CMP, implant, and backend modules for capacity feasibility.
  
  

WIP Control & Lot Handling

• Manage daily fab WIP: status, aging, bank, bottlenecks, special lots.
• Handle Lot Handling Requests (LHN)—change product, hold, release, split/merge, expedite, slow-down.
• Monitor and maintain TTL WIP, remaining input quantities, WAT/WH/Bank levels.
• Control key lots, SHL lots, Customer Pull-in/Pull-out lots, and special event lots.
  
  

Production Plan, Projection & Assumptions

• Prepare weekly and monthly production/output projections.
  
  

Identify And Monitor Key Planning Assumption

• Cycle time per route
• Module capacities
• Bottleneck health
• Tool availability
• Product mix impact
• Manage Consensus Demand vs Plan vs Execution alignment. System & Process Ownership
• Drive PP modules in the Manufacturing Execution System (MES) and Planning System:
• Order management
• Reserve/Commit/Recommit logic
• WIP tracking & forecast
• Plan-group settings
• Daily plan creation & overrides
• Own PP procedures, SOPs, and internal controls.
• Support digital transformation, automation, and data integrity for planning.
  
  

Cross Functional Collaboration

• Work closely with:
• Planning & Logistics
• Module Engineering
• Manufacturing Operations
• Customer Operations
• Quality/PIE
• Supply Chain (Materials/Stores)
  
  

Provide daily plan, recovery actions, and output risk visibility to stakeholders.

Qualification

• Bachelor’s or Master’s degree in Engineering (Electronics, Mechanical, Industrial, Production, Semiconductor, or similar)
  
  

Experience

• 8–12 years experience in MRP within semiconductor fabs, display fabs, or complex high‑mix manufacturing preferred.
  
  

Additional Technical Requirements

• Strong understanding of semiconductor manufacturing flow, routing, and WIP behaviour.
• Expertise in:
• Wafer start scheduling
• WIP management and dispatching
• CT modelling and bottleneck control
• Output projection logic
• Order management and ATP/CTP concepts
• Familiar with MES, ERP, MPS/MRP, and planning dashboards.
• Ability to interpret fab data, constraints, and convert into executable plan
• Analytical Skills
• Excellent quantitative and problem‑solving abilities.
• Ability to forecast output under variability.
• Data‑driven decision-making using dashboards, SQL, Excel, Python
