The Opportunity

We're looking for an organized, detail-oriented Buyer/Planner who enjoys problem-solving, working with suppliers, and keeping materials moving.

In this role, you'll coordinate purchasing and material planning to make sure materials and finished goods are available to support operational needs and customer commitments. You'll work with suppliers and internal teams to manage supply schedules, keep planning and purchasing information accurate, spot potential supply risks, and support delivery and inventory goals.

What You'll Do

• Review approved requisitions and MRP requirements, and plan purchases based on demand, inventory, lead times, and business priorities.
• Confirm supplier pricing, availability, and delivery information.
• Prepare and issue purchase orders and bid requests within your assigned authority.
• Perform material planning and scheduling for assigned products and apply planning parameters to support accurate MRP results.
• Monitor supplier confirmations and open orders, coordinate delivery schedules, and expedite late or at-risk shipments.
• Update ERP dates and records to keep information current.
• Analyze demand, inventory, usage, and shipment data, and support forecasting or projection requests from management.
• Coordinate with suppliers and internal teams to support material availability, customer requirements, and on-time shipment.
• Investigate delivery, quality, invoice, and receipt discrepancies, coordinate corrective actions, and elevate issues as appropriate.
• Coordinate authorized product changes as required.
• Coordinate supplier returns with the supplier, Quality, and Warehouse for NCMRs and other situations, including replacement orders, credits, and follow-up.
• Monitor and process Advance Shipping Notifications (ASNs).
• Perform other related duties as assigned.

Required Qualifications

• Two years of experience in purchasing, material planning, inventory control, logistics, or a related supply-chain role. An equivalent combination of education, training, and experience may be considered.
• Experience using an ERP system, including ERP/MRP systems and maintaining accurate transactional or planning data.
• Working understanding of purchasing, supply and demand, material planning, forecasting, replenishment, inventory management, and logistics.
• Intermediate to advanced Microsoft Excel skills, including formulas, PivotTables, lookup functions such as XLOOKUP or VLOOKUP, and sorting and filtering data.
• Strong analytical, problem-solving, organizational, and time-management skills.
• Ability to review numerical information, identify discrepancies, and prepare or interpret routine reports.
• Strong written and verbal communication skills, including the ability to obtain clarification and communicate issues professionally.
• Ability to manage competing priorities, meet deadlines, and maintain accuracy in a fast-paced environment.
• Ability to work independently within established procedures and approval limits, while escalating issues appropriately.
• Proficiency with Outlook and other standard business applications, and the ability to learn new systems quickly.

Preferred Qualifications

• Associate or bachelor's degree in supply chain management, business, operations, or a related field.

Why You'll Love This Role

• Play a key part in keeping materials, production, and customer shipments on track.
• Work with a variety of suppliers and internal teams every day.

• Develop your purchasing, planning, and supplier management expertise.
• Build your career with a global technology organization.
