• Maintain compliance with all configuration and quality system requirements
• Champion operational standardization, documentation, and cross-training protocols
  
  
  

Qualifications

• 7+ years in manufacturing leadership, preferably in high-mix, high-velocity environments
• Proven experience managing multi-shift teams across multiple facilities
• Strong command of inventory systems, material planning (MRP), and supply chain workflows
• Expertise in lean manufacturing, workflow design, and continuous improvement methodologies
• Fluency in Excel/Google Sheets; experience with production software and ERP/MRP systems (e.g., NetSuite, Fishbowl)
• Strong communication skills with the ability to work cross-functionally and lead from the front
