As a Manager of Warehouse Network Optimization, you will serve as a strategic leader driving the design, placement, and efficiency of AWS"s warehouse network. You will own end-to-end network modeling responsibilities - from gravity analysis and demand-weighted site placement to throughput optimization and strategic footprint rationalization. You will translate complex supply chain data into actionable network strategies, partnering with operations, finance, and supply teams to ensure the right capacity is in the right place at the right time.
MAIN RESPONSIBILITIES:
Network Strategy & Gravity Analysis
Lead gravity modeling and demand-weighted analysis to determine optimal warehouse placement across the North and South America network, balancing inbound origin lanes, outbound delivery density, and transportation lead times.
Build and maintain network optimization models that incorporate customer demand signals, labor market availability, capacity constraints, and market capacity to identify highest-value site locations.
Translate gravity analysis outputs into actionable site recommendations, including facility sizing, lease timing, and build-vs-buy trade-offs.
Partner with modeling teams and internal analytics groups to continuously refine network topology models and stress-test assumptions against demand forecasts.
Material Placement & Flow Optimization
Define strategic material placement frameworks - determining which SKU families, product categories, or inventory types should be positioned at which nodes across the fulfillment network.
Drive replenishment flow optimization between distribution centers minimizing dwell time, transportation cost, and handling touches.
Develop and own slotting strategies and inventory positioning logic that align material flow with throughput capacity and demand velocity.
Identify and resolve misalignment between where material is and where it needs to be, using data-driven root cause analysis and corrective action plans.
Strategic Initiatives & Network Efficiency
Identify and lead cross-functional initiatives to reduce warehousing cost-per-unit through strategic footprint consolidation, network rebalancing, and site utilization improvement.
Own the development and execution of multi-year warehouse network roadmaps, including capacity recovery plans, site exit strategies, and greenfield launch sequencing. Lead workstreams that address network imbalances.
Performance Management & Stakeholder Alignment
Define and track KPIs for network health, including warehouse utilization rates, pallet footprint efficiency, flow velocity, and cost-per-cubic-foot benchmarks.
Build recurring reporting frameworks that surface optimization opportunities and track progress against network strategy goals.
Align with senior building and regional leadership to ensure site-level decisions ladder up to network-level strategy.
Partner with LSPs and 3P service providers to ensure operational execution aligns with the broader network design.
A day in the life
The morning starts with a gravity model refresh - overnight demand signals shifted, and a new concentration of customer density in the Southeast is flagging a potential node gap. By 9am, you"re on a call with supplier managers discussing whether to accelerate transfer of materials to a new site. Midday, you"re reviewing a fulfillment initiative, validating whether material placement aligns with the slotting strategy your team published last quarter. By afternoon, you"re presenting project updates to leadership. The day ends stress-testing tomorrow"s network rebalancing recommendation.
