Job description
Description
Position Summary
The Senior Buyer is responsible for the timely, accurate, and cost-effective procurement of raw materials, tooling, manufacturing supplies, and assigned outside services required to support A1J Technologies’ precision manufacturing operations. As A1J advances from a traditional job-shop model toward a scalable Tier 1 supplier for commercial aerospace and defense customers, this position strengthens supplier reliability, material traceability, purchasing discipline, and delivery performance.
Reporting to the Supply Chain & Logistics Manager, the Senior Buyer executes sourcing and purchasing activities, negotiates with suppliers, expedites critical requirements, and works cross-functionally with Planning & Production Control, Manufacturing Engineering, Production, Quality, Logistics, and Finance. This is a senior individual-contributor role; purchasing strategy, staffing, and departmental leadership remain with the Supply Chain & Logistics Manager.
1. Procurement Execution & Material Availability
Execute purchase requisitions and release accurate purchase orders for assigned raw materials, tooling, consumables, MRO items, and approved outside services within delegated authority.
Review demand, lead times, specifications, inventory availability, and production priorities before placing orders.
Proactively track open purchase orders, obtain supplier acknowledgments, and expedite shortages or delivery risks affecting production commitments.
Coordinate substitutions, split deliveries, and alternate sourcing only through the required Engineering, Quality, and commercial approval processes.
2. Supplier Sourcing, Negotiation & Performance
Identify and qualify prospective suppliers in coordination with Quality and the applicable supplier approval process.
Solicit and evaluate quotations based on total value, lead time, technical requirements, quality, delivery, and commercial terms.
Negotiate pricing, lead times, minimum order quantities, and terms within delegated purchasing authority.
Track supplier delivery and responsiveness; document recurring issues and support supplier improvement and corrective-action activities.
3. Aerospace, Defense & Purchasing Compliance
Ensure purchase orders accurately communicate applicable drawings, specifications, revisions, certification requirements, and customer/quality flow downs as provided by authorized functions.
Purchase from approved sources when required; verify required supplier approvals and coordinate with Quality on supplier status and special-process requirements.
Support material traceability and required certifications, including mill test reports, certificates of conformity, and applicable lot/heat identification.
Maintain purchasing records to support AS9100-aligned processes, audit readiness, product safety, configuration control, and prevention of suspect/counterfeit items.
Escalate export-control, domestic sourcing, customer-approved-source, and other contract-specific requirements to designated compliance owners; do not independently interpret or waive requirements.
4. ERP, Data Accuracy & Purchasing Controls
Maintain accurate supplier, purchase order, promised date, price, and delivery information in the ERP/MRP system.
Ensure purchasing transactions, revisions, acknowledgments, and documentation are completed accurately and promptly.
Partner with Receiving, Inventory/Material Control, and Finance to resolve receiving discrepancies, invoice mismatches, and open purchase order issues.
Identify opportunities to standardize purchasing workflows, reduce manual followup, and improve supplier and material visibility.
5. Cross-Functional Production Support
Coordinate with Planning & Production Control on demand changes, critical shortages, and recovery schedules.
Work with Manufacturing Engineering and CNC Programming to confirm purchasing requirements for raw material, tooling, and manufacturing support items.
Partner with Quality and Receiving on rejected, damaged, incomplete, or uncertified incoming material; support supplier returns and corrective actions.
Collaborate with Logistics and outside-processing coordinators on material movements, subcontracted operations, and supplier commitments where assigned.
Communicate procurement risks and mitigation actions clearly and promptly to stakeholders.
6. Cost Improvement & Continuous Improvement
Identify documented savings through competitive sourcing, supplier consolidation, negotiated pricing, and process improvements without compromising product conformity or delivery.
Analyze recurring expedite charges, lead-time variance, shortages, and purchasing inefficiencies; recommend sustainable corrective actions.
Support standard work, supplier scorecards, purchasing KPIs, and disciplined continuous-improvement initiatives.
