As we continue to grow, we're looking for an Accounts & Supply Chain Administrator to join our team in Abingdon.

Essential 

• Strong Microsoft Excel or spreadsheet skills 
• Excellent numerical accuracy and attention to detail 
• Able to follow processes consistently and accurately 
• Comfortable managing your workload independently

You'll benefit from: 

• Exposure to both Finance and Supply Chain functions 
• The opportunity to help shape future processes 
• Hands-on involvement in business systems transformation 
• A collaborative and supportive team environment 
• The chance to work within a growing high-technology business at the forefront of semiconductor innovation
