• Monitor and adjust critical path items as needed
  
• Perform hands-on inventory tasks and ensure stock data accuracy
  

• Proven negotiation and decision-making skills
  
• Strong organizational habits and attention to detail
  
• Working knowledge of purchasing operations and protocols
  
• Proficiency in Microsoft Word, Excel, and Outlook
  
• Familiarity with MRO practices in industrial settings
