• Manage and resolve critical escalations and exceptions in all areas of the capacity planning
• Build mathematical models to perform simulation and optimization studies of demand and supply projections, scenario planning, and feasibility analysis while balancing various constraints
• Work cross-functionally to define problem statements, collect data, build analytical models and make recommendations to drive change and optimization to inform company-level infrastructure decisions
• Partner across Infra: such as platform teams, operations, networking planning, data center planning as well as Product and Finance teams to find the most optimal ways to scale our Infrastructure
