Tech-SC keeps Amazon's technology infrastructure running, ready, and cost-efficient across the full asset lifecycle. We are looking for a Supply Chain Manager III to build the economic model that proves it. You will design and own the model that quantifies the value Tech-SC delivers that a third party can't match: uptime, readiness, and capital efficiency. You will turn "what is this worth to Amazon" into a defensible number leadership and partner business units rely on to make sourcing and investment decisions. Key job responsibilities - Design and model the Tech-SC supply chain: determine what connections should exist and how capital and capacity are assigned across business units, rather than operating within the chain. - Own fully-loaded cost-to-serve allocation to the customer grain, with transparent, defensible assumptions. - Agree baselines and attribution rules with partner business-unit finance teams, then report value enabled versus value realized so the numbers reconcile to their books. - Build the comparison that answers "why Tech-SC", grounded in incentive and capability, not per-unit price alone. - Translate the model into clear narratives and the few numbers that drive leadership decisions, working from strategy set with your manager and director. - Partner across finance, planning, and customer organizations to source the data the model depends on. A day in the life You move between building and defending numbers. A morning might be spent pulling cost and demand data with a planning partner and pressure-testing a cost-to-serve allocation; an afternoon translating that into a one-page value story for a business-unit review. You work closely with finance partners to align baselines, with supply chain planners on capacity and positioning, and with your leadership to shape strategy. You reason about trade-offs first and allocate costs second. Your output is the analytical backbone the organization uses to decide where Tech-SC competes and how it proves its value.
