Accounts and Supply Chain Assistant

Accounts & Supply Chain Assistant

Abingdon, Oxfordshire | Permanent | £27,250 - £32,250 | Full-time (part-time considered)

Looking for a role where finance meets operations?

At Infinitesima, we're building advanced metrology systems used by the world's leading semiconductor manufacturers to produce next-generation computer chips. Our technology helps enable the devices people rely on every day, from smartphones to AI infrastructure.

As we continue to grow, we're looking for an Accounts & Supply Chain Administrator to join our team in Abingdon. This is more than a typical accounts support role. You'll sit at the heart of our Finance and Supply Chain teams, ensuring supplier invoices are processed accurately while gaining exposure to purchasing, inventory management and business systems.

You'll take ownership of a key business process that keeps our suppliers paid accurately and on time:

• Match supplier invoices against approved purchase orders and goods receipts
• Verify invoice accuracy before payment
• Prepare and maintain verified payment lists for Finance
• Post and code invoices within Xero
• Investigate and resolve discrepancies with internal stakeholders
• Maintain accurate records of invoices processed
• Act as a key link between the Finance and Supply Chain teams
• Support process improvements as the business continues to scale

You might already have experience within accounts payable, purchasing administration or finance support. Equally, you could be someone with strong numerical and administrative skills who enjoys working in a structured, process-driven environment.

• 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
• Strong organisational and communication skills
• Keen to learn about purchasing, invoicing and finance processes

• Previous experience within accounts payable, finance administration or purchasing
• Familiarity with accounting or ERP systems such as Xero, Win Man or SAP
• Understanding of purchase orders, goods receipting or invoice processing

This is an exciting time to join. We're currently reviewing and modernising our ERP systems, giving you the opportunity to play a part in a significant business transformation and gain experience that goes far beyond a traditional Accounts Assistant role.

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

If you're organised, detail-focused and enjoy bringing order to complex processes, we'd love to hear from you.
