Senior Supply Chain Manager, Global Logistics, Domestic First Mile Cost

Global Logistics (GL) is seeking a Senior Supply Chain Manager to own Length of Haul (LOH) optimization and inbound Cost Per Unit (CPU) reduction for Amazon"s Domestic First Mile network. This role is the single-threaded owner of one of DFM"s most critical KPIs - the distance inventory travels from vendor or seller origin to the first Amazon node - directly influencing billions in annual transportation spend.

You will combine strategic thinking with tactical execution: learning how Amazon"s network is designed, how buying and placement systems make decisions, and what influences inbound routing - then finding clever opportunities to move inventory from vendor to customer in as straight a line as possible. You will partner with product managers and technology teams to define requirements and build the solutions needed to structurally reduce LOH. You will use data, analytics, and AI to uncover insights, automate reporting, and drive decision-making.

This is not a role where you wait for direction. You will think like a business owner, deeply understand the cost structure, and drive initiatives from concept through execution. The ideal candidate is intellectually curious, analytically rigorous, comfortable with ambiguity, and energized by the challenge of influencing complex systems they don"t directly control.

Key job responsibilities

• Own the Length of Haul optimization strategy end-to-end - from setting annual targets and building multi-year roadmaps to root-cause analysis, weekly reporting, and initiative execution - delivering measurable reductions in inbound transportation cost across Amazon"s domestic network
• Develop deep expertise in how Amazon"s inbound network is designed and how inventory placement systems make routing decisions; identify and execute structural opportunities to reduce distance through placement optimization, origin intelligence, and network topology influence
• Partner with product management, technology, finance, and operations teams to define requirements, write business cases, and deliver system-level solutions that permanently lower cost per unit at scale
• Lead strategic planning and executive communication - including investment proposals, performance narratives, and quarterly reviews - to influence senior leadership decisions and secure resources for high-impact initiatives
• Leverage data analytics, AI, and automation to build scalable insights, dashboards, and attribution models; lead vendor-facing initiatives including origin optimization coaching and multi-origin shipment strategies

A day in the life

You"ll start your week analyzing inbound transportation performance, identifying root causes behind cost movement - mix shifts, network changes, or routing decisions. Mid-week, you might trace why shipments are traveling farther than planned, write the business case for the fix, and present it to partner teams. You"ll influence how inventory placement models factor vendor proximity, coach sellers on optimal shipment origins, and use AI tools to automate insights that previously took days to produce. You think like a business owner: every mile reduced is dollars saved.
