The Senior Inventory Manager is a leadership role responsible for the development, implementation, and on-going administration of a world-class inventory management program supporting a fleet of more than 33 drill ships operating across all major offshore regions globally. The Manager leads a team of inventory management and asset repair professionals. This role sits at the intersection of operations, finance, supply chain, and engineering, and demands both analytical rigor and the leadership presence to drive alignment across a complex, multinational organization. The role also provides governance and leadership for the Asset Repair Program and condition-managed equipment lifecycle; including rotation, defect handling, overhaul execution, traceability, and cost control.

RESPONSIBILITIES/DUTIES

• Team Development: Build, Lead, and mentor a team of inventory management and asset repair professionals distributed across global locations.  Recruit and retain top talent; foster a high-performance culture grounded in analytical thinking, accountability, and continuous improvement. 
• Build and implement a comprehensive inventory management program and centralized policies. Establish and enforce inventory policies, practices, and governance frameworks that balance operational reliability, risk management, and financial discipline. 
• Apply stochastic modeling techniques — including demand forecasting, probabilistic safety stock calculations, and trend analysis — to optimize inventory levels across the fleet. Balance inventory investment against operational risk and reliability requirements; quantify the cost-benefit tradeoffs of stocking decisions for stakeholder communication. Identify and implement opportunities to reduce excess and obsolete inventory while protecting operational uptime. 
• Define and monitor ERP-based workflows for requisitioning, receiving, issuing, and reconciliation to understand and adjust for impacts to inventory. 
• Own the governance, execution, and continuous improvement of the Asset Repair Program and condition-managed inventory across the equipment lifecycle. Establish global standards and controls for rotating and defect equipment, including condition status, equipment rotation, ownership transfer, work order closure, and logistics flows. 
• Design and manage a cycle counting program across all rig locations and shore-based warehouses. Establish and maintain internal controls that satisfy audit requirements and support accurate financial reporting.   
• Define, track, and report on a comprehensive set of inventory KPIs covering service levels, fill rates, inventory turns, days on hand, excess and obsolete balances, and total cost of inventory. Define and monitor asset repair KPIs, including timely ownership transfers, equipment rotation cycle time, work order and purchase order closure, repair cost, supplier performance, and equipment availability. 
• Build and maintain strong working relationships with Operations, Engineering, Reliability, Maintenance, Procurement, and Finance to ensure inventory strategies support broader business objectives. Drive the organization to adopt data driven purchasing decisions that improve inventory utilization and avoid rig non-productive time.
