Position Summary

The Senior Director, Supply Chain Planning leads global Fab & Wafer Planning and Capacity & Network Planning across internal manufacturing operations and external manufacturing partners. This leader owns the global wafer-start plan and long-range capacity roadmap, ensuring that technology, equipment, facilities, materials, and partner capacity support business priorities and product lifecycle requirements.

The role connects rolling 13-week wafer execution with 24-month supply visibility and a 12–60-month capacity and network strategy. Working with Business Unit Supply Chain Leads, Fab and Factory Operations, Procurement, Engineering, Quality, and Finance, the Senior Director translates approved business requirements into feasible supply plans and investment recommendations.

Key Responsibilities

Global Fab and Wafer Planning

Lead the global wafer-start planning process across internal fabs and strategic foundry partners, determining what to start, where to start it, and when.

• Translate approved product requirements and BU priorities into die, wafer, process, and technology-node requirements.
• Incorporate fab, assembly, and test yields, manufacturing cycle times, and work-in-process availability into wafer-start and output plans.
• Balance production requirements across fabs, foundries, critical tools, and constrained process steps.
• Publish rolling wafer-start plans, raw wafer requirements, and material readiness gates aligned with downstream factory and contract manufacturing needs.
• Partner with Operations, Engineering, and Quality to validate planning assumptions and address gaps in yield, cycle time, technology readiness, and output.
• Establish recommendations for wafer and die buffers that balance supply continuity with inventory exposure.

Capacity and Network Planning

• Own the 12–60-month capacity roadmap across internal fabs, factories, foundries, outsourced assembly and test providers, and contract manufacturing partners.
• Develop resource models covering cleanroom space, lithography, epitaxy, assembly, test, labor, engineering support, and other critical constraints.
• Evaluate capacity requirements under base, upside, and downside business scenarios, incorporating product mix, technology transitions, ramp timing, and yield assumptions.
• Assess internal expansion, external manufacturing, second-source options, and geographic alternatives in partnership with Operations and Procurement.
• Develop capacity investment recommendations with Finance and Operations, including timing, decision triggers, expected returns, and execution risks.
• Recommend product-to-site allocations that balance capability, cost, lead time, resilience, and geographic exposure.
• Define external capacity reservation requirements and risk assumptions for Procurement to incorporate into commercial agreements.

Integrated Supply and Lifecycle Readiness

• Align wafer and capacity plans with the integrated material and fulfillment plan, ensuring consistency across manufacturing stages.
• Partner with BU Supply Chain Leads to support new product introductions, production ramps, technology transfers, sustained production, and end-of-life transitions.
• Identify the capacity and material readiness conditions required to support program milestones and production commitments.
• Coordinate with Materials & Inventory Planning on strategic reserves, buffer placement, and inventory exposure associated with long manufacturing lead times.
• Develop recovery scenarios for capacity shortages, yield losses, equipment delays, and partner constraints, with clear owners and decision deadlines.
• Provide leadership with quantified tradeoffs and recommendations when available capacity cannot support business priorities.

Planning Leadership and Governance

• Build and lead a global planning organization spanning fab and capacity planning teams across sites, including SAG, ROW, Caswell, and Greensboro.
• Establish common planning methods, calendars, capacity models, data standards, and performance measures.
• Develop planning leaders and specialists through clear accountability, coaching, and succession planning.
• Maintain a consolidated view of capacity constraints, mitigation plans, investment dependencies, and supply risks.
• Partner with Supply Assurance & Planning Excellence to improve scenario analysis, planning systems, parameter accuracy, and corrective-action discipline.
• Lead executive capacity and wafer supply reviews, presenting decisions required and tracking actions through completion.

Key Partnerships and Decision Responsibilities

• BU Supply Chain Leads: Set business priorities and own program and product lifecycle outcomes from NPI through EOL.
• Material Planning & Fulfillment: Owns the integrated tactical supply plan, master production schedule, and available-to-promise view.
• Fab and Factory Operations: Own production execution and local scheduling; jointly validate capacity, cycle-time, and recovery assumptions.
• Procurement: Owns supplier commitments, sourcing, and commercial agreements, including foundry and contract manufacturing relationships.
• Materials & Inventory Planning: Owns inventory policies and component planning, informed by wafer and capacity requirements.
• Finance, Engineering, and Quality: Partner on investment evaluation, technology readiness, yield assumptions, and manufacturing qualification.

Required Qualifications

• Bachelor’s degree in Supply Chain, Industrial Engineering, Operations Management, Engineering, or a related discipline, or equivalent relevant experience.
• At least 12 years of progressive experience in supply chain or manufacturing planning, including at least five years leading teams across multiple sites or regions.
• Demonstrated leadership in semiconductor, photonics, or similarly complex manufacturing environments with wafer fabrication and downstream assembly or test operations.
• Experience leading wafer-start planning, manufacturing capacity planning, and long-range supply network decisions.
• Strong understanding of yield-adjusted planning, manufacturing cycle times, work-in-process management, bottleneck analysis, and inventory tradeoffs.
• Experience coordinating internal manufacturing and external foundry, outsourced assembly and test, or contract manufacturing capacity.
• Ability to evaluate capital investment and manufacturing alternatives with Finance, Operations, and Procurement.
• Experience with ERP, advanced planning systems, and analytical tools used for capacity modeling and scenario evaluation.
• Strong executive communication skills and a record of driving decisions across organizational boundaries.

Preferred Qualifications

• Advanced degree in Engineering, Supply Chain, Operations, or Business Administration.
• Experience in optical components, photonics, compound semiconductors, or related manufacturing technologies.
• Experience consolidating planning teams and standardizing processes across a global manufacturing network.
• Experience supporting major capacity expansions, manufacturing transfers, and technology ramps.
• Familiarity with SAP, Oracle, Kinaxis, or comparable planning platforms.
• ASCM CPIM or CSCP certification.

Measures of Success

• Improved wafer-start adherence, die availability, and yield-adjusted supply plan attainment.
• Accurate capacity and cycle-time assumptions, with healthy work-in-process levels.
• Capacity readiness aligned with product ramps and business commitments.
• Timely investment and capacity reservation decisions.
• Reduced exposure to bottlenecks and single points of failure.
• Balanced capacity utilization, inventory investment, and supply resilience.
• Consistent planning processes and effective collaboration across global sites and manufacturing partners.
