This role leads a team of 6–9 direct reports across Supply Assurance (buyers) and Material Handlers, overseeing procurement, warehousing, and shipping for a site inventory of 3,200+ unique parts. The Materials Supervisor ensures uninterrupted material flow — from incoming supply, to the production floor, to daily shipments to the offsite Distribution Center — keeping production running and customer demand met. 

The role blends hands-on daily execution with longer-term strategic planning: 

• Day-to-day: Monitor and act on ERP signals, resolve urgent shortages, escalate supply issues, and manage all material movement.

How You’ll Make an Impact:

• Supervise and develop a team of 6–9 direct reports across Supply Assurance (buyers) and Material Handlers, assigning work, setting performance expectations, and monitoring output for accuracy and timeliness. 
• Oversee end-to-end warehouse logistics — receiving, storage, transfers, shipping, and material flow — ensuring accurate ERP/SAP transactions across 3,200+ unique parts. 
• Manage materials requirements alignment with the current supply plan and targeted inventory metrics, adjusting for fluctuating priorities. 
• Complete required ERP transactions directly for procurement and warehouse functions and be able to audit and correct within the ERP system as needed. 
• Assess resource capacity (personnel, equipment, materials) against current and long-term demand, partnering with operations and leadership on utilization and constraint mitigation. 
• Lead or support Lean and continuous improvement initiatives to optimize inventory levels, minimize production costs, and reduce scrap. 
• Use data analytics to monitor inventory levels and inventory turns, and forecasts, responding promptly to demand and operational changes affecting customer needs. 
• Prepare reports and data analysis as needed, communicating insights clearly to cross-functional stakeholders. 

What You Bring: 

• Education: Bachelor's degree (BA/BS) in Business, Supply Chain Management, or related field, or equivalent combination of education and experience. 
• Work Experience: 2+ years of experience in production, warehousing, and procurement, (experience in procurement and warehousing highly desirable); 2+ years of supervisory experience in a union environment preferred. 
• Experience in an ISO certified batch managed chemical site or bio-technology manufacturing site desirable. 
• Solid understanding of transactional ERP (SAP) and MRP systems. 
• Proven project management capability. 
• Strong PC/software skills (Excel, Word, PowerPoint, database, and manufacturing software).
• Excellent leadership, influencing, and communication skills. 
• Proven analytical and problem-solving ability with demonstrated capacity for sound business decision-making. 
• Experience developing direct reports and building high-performing teams across multi-departmental organizations.
