The Senior Buyer Planner will join the Supply Chain team and own the buy side of the material plan, converting demand into purchase orders and maintaining accurate supply visibility in the ERP system. This is a high-volume, high-judgment execution role where long lead times, demand shifts, and custom/single-source materials require disciplined queue management and persistent vendor follow-up.
Key responsibilities include:
**Purchasing Execution:** Review the buyer workbench daily for new demand, pull-ins, quantity changes, and cancellations. Release compressed lead-time purchase requests first, prioritizing items past the Suggested Order Date, then batch standard releases. Create Transfer Orders to connect supply and demand across locations and subsidiaries. Work the purchase request intake queue end-to-end, including requests needing vendor assignment, quote requests, returned/rejected requests, and approved requests without POs. Provide status updates to requesters on aging items.
**Delivery & Supplier Management:** Chase purchase order acknowledgments where vendors have not confirmed price, quantity, and delivery date. Confirm delivery dates and update POs with each new committed date. Drive expedite and pull-in requests for material creating shortages or compressed dates.
**Data Integrity & Financial Accuracy:** Resolve three-way match discrepancies (price variance, quantity variance, missing receipts) by correcting the actual wrong record rather than forcing invoices through. Establish and maintain lead times in NetSuite for items missing them. Identify and load preferred vendors and vendor part numbers for items missing them.
Travel up to 5% domestic or international.
**Requirements:**
- 2+ years of purchasing, buying, or materials planning experience in a manufacturing environment, or equivalent combination of education and experience
- Bachelor's degree in Supply Chain, Operations, Business, or related field, or equivalent practical experience
- Working knowledge of MRP/ERP purchasing mechanics (planned orders, suggested order dates, lead time logic, exception messages)
- Direct experience managing vendor relationships and holding suppliers to committed delivery dates
- Strong Excel skills (pivot tables, lookups, ability to build working analysis without waiting on report requests)
- Ability to read and interpret BOMs and engineering drawings to buy the right part
- Organized and persistent; able to work a large daily queue to completion and communicate status clearly
**Preferred Qualifications:**
- Experience with NetSuite or comparable Tier 1/Tier 2 ERP
- Experience with intake or procure-to-pay tools (Zip, Coupa, Ariba)
- Background in high-mix/low-volume, prototype-to-production, or new product introduction environments
- APICS/ASCM certification (CPIM, CPSM, CSCP) or active pursuit
- Experience buying custom fabrication, machined parts, electronics, or long-lead capital equipment
- Familiarity with three-way match, receiving, and AP resolution workflows
- Working knowledge of business analytics reporting tools
