• Drive supplier selection and present sourcing recommendations to leadership with clear cost, risk, and schedule trade-offs
• Monitor component pricing, market trends, and regulatory and tariff changes, adjusting sourcing plans proactively
• Mentor junior team members and contribute to team standard work
