We are looking for a proactive and detail-oriented Material Buyer to support Lumentum’s global high-precision manufacturing operations. This role is responsible for purchasing direct materials, ensuring timely supply, managing suppliers, and supporting production continuity for both NPI and mass-production builds. The Material Buyer works closely with Planners, Commodity Managers, Engineering, Quality, and global Supply Chain teams to secure materials, drive supplier performance, and maintain strong operational execution.
Responsibilities
Manage end-to-end purchasing activities for direct materials required to support engineering builds, NPI, and volume production.
Execute purchase orders based on MRP signals, build plans, and production requirements; ensure accuracy in pricing, quantity, and delivery schedules.
Track and monitor open POs; follow up with suppliers on delivery commitments, expedite urgent materials, and resolve supply delays.
Coordinate closely with Production Planners and Master Control to ensure material readiness and avoid line-down situations.
Partner with Global Commodity Managers to support supplier qualification, cost negotiation, forecast alignment, and contract compliance.
Work with suppliers to obtain commits, recovery plans, and solutions for shortages, late deliveries, quality issues, or capacity constraints.
Collaborate with Engineering and NPI teams to support BOM changes, ECO implementation, engineering samples, and material readiness for trial builds.
Maintain accurate procurement master data—pricing, MOQ, lead time, planning parameters, and supplier information—to support effective planning and inventory control.
Support cost-reduction initiatives, material cost analysis, supplier consolidation, and productivity improvement projects.
Coordinate with IQA, SQE, and Engineering to resolve NCRs, quality issues, and material dispositions (RMA, replacements, rework, scrap).
Review and manage material risks: shortages, E&O exposure, unplanned demand, and long-lead items.
Collaborate with Warehouse and Logistics to ensure inbound materials, import/export, and receiving processes are supported.
Prepare purchasing reports, material status updates, and supplier performance summaries for internal stakeholders.
Ensure adherence to Lumentum’s purchasing policies, compliance standards, and global sourcing processes.
Perform any additional tasks or responsibilities assigned by the Manager.
Qualifications
Bachelor’s degree in Supply Chain, Business Administration, Engineering, or related field.
At least 7 years of experience as a Material Buyer / Direct Buyer / Purchasing Specialist in high-tech or manufacturing industries.
Hands-on experience with MRP/ERP systems (Oracle preferred) for PO management, material planning, and supplier follow-up.
Strong understanding of direct materials, BOM structures, inventory control, and supply chain processes.
Good negotiation, communication, and supplier management skills.
Ability to analyze data, identify supply risks, and drive corrective actions effectively.
Proficiency in Microsoft Excel and experience preparing planning or purchasing reports.
Ability to work under pressure, manage multiple priorities, and support dynamic build requirements.
Familiarity with quality processes (IQA, NCR, SQE) and engineering change control is a plus.
Experience working with global suppliers and cross-functional teams is an advantage.
