Core Responsibilities

Primary Functions

Supervise daily parts operations including receiving, put-away, picking, packing, shipping, and returns to maintain continuous parts flow and meet SLA targets for production and field service.
Lead, coach, and schedule a team of parts associates and material handlers; conduct performance reviews, provide development plans, and recruit to maintain staffing levels aligned with demand.
Maintain accurate parts inventory using WMS/ERP (e.g., SAP, Oracle, JD Edwards) — perform and validate cycle counts, root-cause discrepancies, and drive corrective actions to achieve inventory accuracy targets.
Plan and execute periodic physical inventories and reconciliations; prepare variance reports, investigate stock differences, and implement process changes to prevent recurrence.
Manage parts replenishment and ordering processes: review min/max levels, generate purchase requisitions, coordinate with purchasing/vendors, and expedite critical parts to prevent production or service downtime.
Oversee inbound receiving and vendor inspections: validate packing lists, inspect shipments for damage or short-shipments, document claims, and coordinate vendor resolutions.
Optimize warehouse layout and storage strategies for parts by size, turnover, and criticality to reduce picking time and improve space utilization.
Enforce safe work practices and regulatory compliance (OSHA, DOT as applicable): conduct safety audits, toolbox talks, incident investigations, and corrective actions.
Implement and sustain continuous improvement initiatives (5S, Kaizen, Lean) to reduce lead time, scrap, and handling costs while improving throughput.
Manage returns, warranty, and obsolete parts flows: disposition parts, coordinate RMA processes, and update inventory records accordingly.
Monitor and report on key KPIs — inventory accuracy, fill rate, on-time shipping, picking productivity, shrinkage — and present results to operations leadership with recommended improvements.
Coordinate cross-functional communication with production planning, maintenance, field service, purchasing, and sales to prioritize parts allocation during constrained supply.
Execute pick-pack-ship operations for customer and internal orders, including kitting and pre-assembly of parts kits for service technicians or production sequences.
Maintain and update parts master data in ERP/WMS (part numbers, descriptions, tracking, bin locations, lead times, safety stock) to ensure data integrity and searchability.
Implement barcode/RFID labeling and scanning procedures to improve traceability, reduce errors, and speed up transactions in the warehouse.
Drive cost control through vendor negotiation input, freight optimization, and reduction of obsolete stock; collaborate with procurement on supplier performance.
Provide leadership during system upgrades or WMS/ERP implementations: define requirements, support testing, train users, and validate data migration for parts modules.
Manage third-party logistics (3PL) or off-site storage relationships when applicable: monitor service levels, billing, and compliance with contractual SLAs.
Ensure parts documentation and regulatory records (MSDS, certificates of conformance, calibration records for serialized assets) are maintained and retrievable.
Respond to escalated customer and field service issues related to parts availability, lead times, and order accuracy; provide timely status updates and problem resolution.
Develop and deliver training programs and SOPs for parts handling, picking accuracy, safety, and system use to maintain consistent operational standards.
Coordinate special projects such as new product introductions, seasonal demand surges, or facility expansions that impact parts planning and storage.

Secondary Functions

Support continuous improvement projects by providing operational insight, participating on cross-functional teams, and implementing agreed process changes.
Assist with budgeting and forecasting activities for parts inventory and warehouse operating expenses; provide historical usage trends and demand drivers.
Maintain parts catalogs, BOM/kit relationships, and interchange/alternate part references to improve parts selection and reduce mispicks.
Facilitate vendor returns, credits, and warranty repairs; track resolution and update inventory and financial records.
Support IT and data teams with warehouse-related requirements, testing, and process documentation during system enhancements.
Participate in internal and external audits related to inventory, quality, and safety; prepare documentation and execute corrective action plans.
Provide input into procurement supplier scorecards and vendor performance reviews specific to parts deliveries and quality.
Act as backup for related administrative functions such as order entry, invoicing verifications, and supplier communications during peak times.
Collaborate with field service leadership to design and maintain parts kits and van inventory strategies for remote technicians.
Maintain a parts obsolescence program and drive disposal or liquidation strategies to recover working capital.
