Amazon's Middle Mile Fleet Management business is scaling fast, and preventive maintenance is central to how we keep it running. If you want to take an established program to the next level of maturity — bringing rigor, data, and mechanisms to a business that already moves at Amazon scale — this is the place for you. The Middle Mile organization operates and maintains a large, growing fleet of over 100,000 assets — tractors, trailers, box trucks, and hostlers. In this role you will raise the bar on how we maintain those assets, wearing many hats in a highly collaborative environment. This role requires strong leadership, the ability to identify trends with limited data, and the influence to align teams across Amazon to advance our maintenance business. This Program Manager will own the vision, roadmap, and end-to-end execution of Amazon's Preventive Maintenance (PM) strategy for the Middle Mile fleet. Preventive maintenance is the single largest lever we have to maximize asset uptime, reduce unplanned breakdowns, extend asset life, and lower total cost of ownership across the fleet. Key job responsibilities Own the PM strategy and roadmap. Define the multi-year vision for scheduled maintenance across tractors, trailers, box trucks, and hostlers — setting the PM cadence, compliance targets, and completion standards that maximize uptime while balancing shop capacity, network availability, and cost. Drive measurable reliability outcomes. Move the metrics that matter — VORR/uptime, PM and PMDOT compliance, MTBF/MTBG, unplanned downtime, and cost per mile — using data to catch failure trends before they become breakdowns. Smooth and optimize PM volume. Work backwards from network demand and shop capacity to level PM workload across the year, including peak-period planning, so maintenance stays on schedule without disrupting operations. Own and build the reliability tooling. Build the AI-driven mechanisms — automated WBR pipelines, QuickSight downtime dashboards, and deep-dive generation — that surface failure trends and drive the right maintenance actions at scale. Hold vendors and OEMs accountable. Enforce quality through data-driven scorecards and 3rd-party audits, feeding reliability learnings into future asset purchases. Influence across the org. Align Operations, Finance, Capital Planning, vendor networks, and senior leadership — balancing long-term strategy with day-to-day execution.
