• Maintain planning and procurement data integrity in the ERP system, including supplier commitments, planning parameters, item data, delivery dates, quote information, purchase order status, and material availability.
• Manage or support Kanban programs for consumables, wire, test/select resistors, customer-specific materials, and other demand streams not fully driven through standard ERP/MRP signals.
• Support long-range material planning for legacy customers, including one-year to eighteen-month demand visibility, critical reporting, qualification builds, purchased components, SOW changes, and production readiness activities.
• Process supplier invoices, resolve purchasing discrepancies, support cost analysis, and identify cost savings, lead-time reduction, alternate sourcing, and make-versus-buy opportunities.
