• Coordinate engineering teams to build prototype SST products.
• Build and maintain an integrated project schedule with clear milestones, dependencies, owners, and critical path.
• Track procurement, long-lead items, and vendor deliveries; escalate supply chain risks before they become blockers.
• Coordinate engineering change orders (ECOs) and configuration control through Arena PLM.
