Summary

We are seeking a hands-on, energetic, highly adaptive Capacity Planner in our Bangkok, Thailand office to support a fast-paced, vertically integrated manufacturing operation operating under extreme demand variability driven by evolving market dynamics, AI-enabled forecasting, and rapid product evolution.

This role is at the heart of aligning demand signals, capacity constraints, and supply availability. The ideal candidate combines strong fundamentals in demand and supply planning models with the ability to innovate, experiment, and act quickly in a volatile environment. You will translate complex, often imperfect signals into executable capacity plans that keep operations, supply chain, engineering, and customers aligned.

This is a critical role for someone who thrives in ambiguity, embraces change, and is ready to own outcomes—not just forecasts.

Key Responsibilities

Internal Capacity Modeling & Planning

• Develop, own, and continuously improve an internal capacity model that translates dynamic customer demand into actionable capacity requirements.
• Manage short-, mid-, and long-term capacity planning horizons, providing clear visibility into constraints, bottlenecks, and trade-offs.
• Assess capacity impacts from demand variability, product mix changes, ramp programs, yield performance, and engineering updates.

Support Customer-Driven Demand Dynamics

• Analyze rapidly shifting customer demand signals and convert them into capacity scenarios, including upside, downside, and allocation cases.
• Partner with demand planning, sales, and program teams to evaluate feasibility, risk, and fulfillment options.
• Provide data-driven recommendations to support customer commitment decisions in a highly dynamic market environment.

Cross-Functional Planning Collaboration

• Work closely with internal production and supply planners, providing capacity assumptions, scenarios, and guidance to support execution plans.
• Serve as the bridge between demand signals and supply execution, ensuring internal plans are aligned before release to external partners.
• Collaborate with Engineering, Operations, and Supply Chain to ensure capacity models reflect current processes, yields, and constraints.

CM Support (Indirect Interface)

• Enable internal planners who directly manage Contract Manufacturers (CMs) by supplying:
  
  • Capacity scenarios and constraints
  • Demand assumptions and risk assessments
  • Data to support capacity commitments and recovery planning
• Align internal capacity planning assumptions with external supply realities through regular coordination with CM-facing planners.

Data, Tools & AI-Driven Insights

• Build and maintain advanced Excel-based models to simulate capacity, throughput, and constraint behavior.
• Leverage AI-enabled forecasts or advanced analytics to improve responsiveness and scenario robustness.
• Drive continuous improvement in planning logic, automation, and scalability of capacity models.

Performance Monitoring & Continuous Improvement

• Track and analyze capacity utilization, constraint drivers, and planning accuracy.
• Identify structural gaps between demand and capacity and recommend mitigation paths.
• Continuously refine planning processes to improve speed, clarity, and decision quality.

Required Qualifications

• Bachelor’s degree in Supply Chain Management, Industrial Engineering, Operations Management, MIS, or a related field
  OR equivalent hands-on experience (5+ years) in capacity, demand, or production planning.
• Strong foundation in demand and supply planning concepts, including constraint-based planning and scenario analysis.
• Proven experience working in dynamic, fast-changing manufacturing environments.
• Advanced Excel skills (mandatory); ability to build and maintain complex planning models.
• Working knowledge of ERP/MRP systems in a manufacturing context.
• Strong analytical thinking with the ability to move from data to action quickly.
• Clear, confident communicator capable of influencing across all organizational levels.

Preferred Qualifications

• Experience integrating or consuming AI / advanced analytics outputs for planning or forecasting.
• Exposure to TEC, semiconductor, advanced manufacturing, or highly engineered products.
• Experience supporting multi-site or 24/7 manufacturing operations.
• Familiarity with SQL, Access, or data visualization tools.
• Demonstrated track record of improving planning processes, tools, or systems.
