Materials Manager

Description Please note that this posting is for a contract assignment and is not a full-time employment opportunity with Amazon. Candidates selected for roles will be employed as contract workers through Amazon’s approved 3rd party Direct Source provider for the duration of the specified project and will not be an employee of Amazon. Amazon Robotics doesn't just build robots — we manufacture the future of fulfillment. At our facilities in the greater Boston area, ideas move from whiteboard to production floor at a pace most companies can't match. Our manipulation systems — robotic arms, grasping technologies, and autonomous pick-and-place solutions — are among the most complex and rapidly evolving products in our portfolio. And they need someone who can make the impossible plannable. We are seeking an Inventory and Manufacturing Planner to own inventory strategy, configuration management, and production planning for our robotic systems at BOS12/BOS27/BOS35. You will build the planning and inventory control infrastructure for systems that are actively scaling from early development to full production. This role requires deep expertise in manufacturing planning, the judgment to make high-impact decisions in ambiguous environments, and the technical credibility to influence engineering and operations partners. You will develop inventory control policies, own the full lifecycle of engineering and manufacturing change orders, build MBOMs, create finite production schedules, and release work orders. You'll drive inventory accuracy, eliminate excess and obsolete material, and ensure that when engineering says "ready to build," manufacturing actually can. We're looking for a seasoned professional who has built these capabilities before and knows what good looks like — someone who brings proven frameworks, adapts them to new environments, and delivers results across cross-functional boundaries. Key job responsibilities Develop and enforce inventory control policies and procedures; drive accuracy through cycle count programs, root cause analysis, and corrective actions Optimize inventory levels and reduce E&O through proactive lifecycle management, disposition strategies, and demand-aligned replenishment Develop new inventory strategies that scale with program growth and evolving manufacturing requirements Own Engineering Change Orders (ECOs) and Manufacturing Change Orders (MCOs) across supported programs Build and maintain Manufacturing Bills of Materials (MBOMs) with full configuration accuracy and traceability Set up and maintain Bills of Distribution and Sourcing Rules; partner with engineering on master data, routings, and resource rates Create finite capacity production schedules considering equipment, labor, and material constraints Develop build schedules and release work orders through their complete lifecycle, with emphasis on early NPI programs Develop and maintain short-term and medium-term capacity models; identify and resolve bottlenecks through constraint analysis Perform sequence optimization to minimize changeovers and maximize manufacturing throughput Build KPI dashboards to track inventory and planning performance; use data to drive decisions Drive continuous improvement through Lean/Six Sigma methodologies Collaborate cross-functionally with engineering, manufacturing, procurement, and logistics on supply plan execution Basic qualifications Bachelor's degree, or 2+ years of professional or military experience Knowledge of supply chain management concepts - forecasting, planning, sourcing, optimization and logistics or equivalent Experience in high-volume manufacturing environments Experience with reporting and Data Visualization tools such as Quick Sight / Tableau / Power BI or other BI packages Knowledge of Six Sigma tools and Lean techniques Experience in stakeholder and communication management Experience with engineering change management (ECOs/MCOs) and BOM management Proficient in ERP systems and supply chain planning tools Preferred qualifications Experience with SQL APICS Certification (CPIM or CSCP) Role Location is BOS12 or BOS27 This posting is for a contract assignment with Tundra Technical Solutions to provide services to Amazon.
