• Lead RFQ/RFP activities, including supplier identification, quote solicitation, bid analysis, supplier selection, and commercial negotiations.
• Evaluate suppliers based on quality, technical capability, capacity, cost, lead time, responsiveness, financial considerations, and overall supply-chain risk.
• Negotiate pricing and commercial terms, including lead times, minimum order quantities, payment terms, delivery requirements, cancellation/rescheduling provisions, and other applicable terms.
• Identify and implement opportunities for competitive sourcing, dual sourcing, localization, and supplier consolidation where appropriate.
• Evaluate total cost of ownership when making sourcing and supplier-selection decisions.

Purchasing & Material Management

• Manage Purchase Requisition (PR) and Purchase Order (PO) processes supporting R&D and Production.
• Analyze purchase requisitions for accuracy, completeness, specifications, required dates, and appropriate approvals.
• Place and manage purchase orders and provide timely delivery and schedule feedback to internal stakeholders.
• Maintain accurate supplier pricing, lead-time, delivery, and purchasing information within SAP/ERP systems.
• Update product BOMs and purchasing information records with current lead times and pricing.
• Monitor open purchase orders, past-due orders, shortages, and critical material requirements and proactively resolve delivery issues.
• Execute material and trace transactions within the ERP system.
• Maintain accurate delivery schedules in ERP, Material Status reports, and applicable Program Management planning tools.
• Review Clean to Start (CTS) requirements and take appropriate procurement actions to support Engineering Project Plans and Production schedules.

Supplier Management & Performance

• Develop and maintain strong working relationships with key suppliers.
• Establish, monitor, and communicate supplier performance against key metrics, including: On-Time Delivery (OTD), Quality, Cost, Lead time, Responsiveness, Capacity and supply continuity.

• Partner with Quality, Engineering, and Manufacturing to resolve supplier quality issues and support supplier corrective-action activities.
• Work with suppliers to improve delivery performance, reduce lead times, improve quality, and increase overall supply-chain effectiveness.
• Escalate significant supplier performance, capacity, quality, or commercial issues in a timely manner.

Cost Management & Continuous Improvement

• Identify, negotiate, implement, and track cost-reduction and cost-avoidance opportunities.
• Analyze supplier quotes, historical pricing, market conditions, and cost drivers to support fact-based negotiations.
• Support annual and project-specific cost-reduction objectives.
• Identify opportunities to improve procurement processes, supplier performance, inventory efficiency, and purchasing productivity.
• Track and report measurable procurement results, including cost savings, purchase price variance, supplier performance, shortages, and other assigned KPIs.

Supply-Chain Risk Management

• Proactively identify supply-chain risks, including sole-source suppliers, long-lead materials, capacity constraints, supplier financial concerns, geopolitical/logistics exposure, and material shortages.
• Develop and coordinate appropriate mitigation plans in partnership with Engineering, Operations, Quality, and other stakeholders.
• Identify alternate suppliers and second-source opportunities for critical materials.
• Monitor component obsolescence and end-of-life notifications and coordinate alternate-source or redesign activities with Engineering as required.
• Proactively communicate material risks that could impact engineering milestones, production schedules, customer commitments, or company objectives.

Engineering, NPI & Cross-Functional Support

• Review Engineering Change Orders (ECOs) and work with Engineering and Manufacturing to develop appropriate procurement and material-transition plans.
• Support New Product Introduction (NPI) activities from prototype and development through production release.

• Support make-versus-buy, supplier-selection, and sourcing decisions as required.
• Collaborate with Engineering, Quality, Manufacturing, Planning, Program Management, Finance, and other functions to ensure material readiness.
• Participate in cross-functional meetings addressing material availability, supplier issues, production readiness, and program schedules.
• Work closely with the Eugenus procurement team in Korea and other global partners to coordinate sourcing and procurement activities.

Inventory & Planning

• Manage assigned Min/Max inventory programs.
