The Senior Supply Chain Planner independently leads end-to-end supply planning for assigned semiconductor product lines, from wafer start through outsourced assembly and test to customer shipment. The role balances customer demand, material availability, capacity, cycle time, yield, inventory, and supplier constraints; leads resolution of complex supply issues; and provides recommendations that support customer commitments and business objectives.

This position has responsibility for:

Own the executable supply plan for assigned product lines across wafer fabrication, assembly, test, and finished-goods stages. Independently balance customer priorities, capacity, material constraints, cycle times, yields, and inventory targets to optimize on-time delivery and overall supply performance.

Develop and evaluate supply, capacity, and allocation scenarios for demand changes, supplier disruptions, yield excursions, product transitions, and other constraints. Assess customer-service, revenue, inventory, cost, and operational implications and recommend a course of action to business leadership.

Lead resolution of complex supply and delivery issues spanning Operations, Sourcing, Engineering, Quality, Finance, Sales, and external manufacturing partners. Perform root-cause and business-impact analysis, develop recovery plans, and align stakeholders on corrective actions and revised commitments.

Represent Supply Planning in new-product introduction and high-volume manufacturing readiness reviews. Assess material, supplier, capacity, lead-time, yield, and inventory risks; recommend mitigation plans; and confirm supply readiness before key launch and ramp milestones.

Serve as the supply-planning subject-matter expert for assigned product lines. Validate capacity, lead-time, yield, and inventory assumptions; identify gaps or distortions; and influence Global Planning and cross-functional partners to improve plan quality and execution.

Govern planning parameters, master data, Bills of Material, Bills of Operations, supply orders, and related ERP transactions for assigned products. Analyze exceptions, determine corrective actions, and drive resolution of systemic data or transaction issues that could disrupt supply.

Manage purchase-order and assembly work-order requirements, supplier commitments, and commercial exceptions based on the approved supply plan, partnering with Sourcing and Finance to protect production continuity, customer commitments, and financial accuracy.

Lead recurring supply reviews and monitor planning performance measures, including on-time delivery, schedule adherence, cycle time, inventory exposure, forecast consumption, and supplier commitment performance. Communicate risks and decisions and initiate corrective action when results deviate from plan.

Lead cross-functional improvements to planning processes, parameters, analytics,…
