• Coordinate routine engineering changes, product transitions, and supplier implementation activities with Engineering, Planning, Manufacturing, Quality, and the Sourcing Team.
• Conduct operational RFQs and market evaluations for lower-spend or non-strategic requirements while escalating major commercial decisions, supplier selection, contracts, and significant financial impacts to the Sourcing Team.
• Identify cost-saving opportunities, validate supplier price changes, and support implementation of sourcing decisions and commercial agreements established by the Sourcing Team.
• Provide day-to-day guidance, onboarding support, and practical mentorship to less experienced buyers.
• Lead continuous improvement initiatives that strengthen purchasing processes, supplier performance, inventory management, ERP data quality, and operational efficiency.
• Maintain accurate purchasing records, supplier information, and ERP data while ensuring compliance with company policies, contractual requirements, quality standards, and applicable regulations.
