As a Worldwide Supply Demand Planner at Apple Inc, you will analyze and coordinate logistical functions, managing the entire product lifecycle from acquisition to disposal. Your core responsibility will be to develop, communicate, and execute end-to-end product demand and supply plans across all distribution channels in over 80 countries. This involves forecasting demand, inventory, and multi-channel sell-through, as well as generating weekly and quarterly supply plans aligned with financial objectives. You will also evaluate risks, implement contingency plans, and analyze daily product sales to identify opportunities and drive partner action. Close coordination with regional product planning, Marketing, and New Product Operations teams is essential for setting launch quantities and ensuring smooth product transitions. Partnering with global procurement teams to allocate constrained components, meet raw material inventory targets, and minimize material obsolescence is also key. You will present product updates and recommend actions to executive management weekly, and identify process improvement opportunities, marshal resources, and drive projects to completion.
