• Manage cylinder-related workflows, including picking, changeover, installation preparation, scheduling, inventory control, loading, and shipment preparation, ensuring employees are trained before performing assigned duties.
• Coordinate specialized receiving and consignment inventory and oversee assigned HEROSE-related requests and product documentation.
• Monitor and report key operational measures such as safety, attendance, inventory accuracy, receiving turnaround, order accuracy, on-time shipment, productivity, backlog, and rework.
• Use operating data, employee input, and root-cause analysis to identify bottlenecks, reduce errors and waste, improve layout and material flow, standardize work, and sustain continuous-improvement actions.
• Partner with Customer Service, Sales, Purchasing, Production, Finance, and other teams to resolve shortages, priorities, order exceptions, system issues, and customer-impacting disruptions.
• Maintain accurate warehouse records, work instructions, training records, and operational documentation; support audits and provide timely updates to leadership.
