Job description

Accounts & Supply Chain Assistant

Abingdon, Oxfordshire | Permanent | £27,250 - £32,250 | Full-time

Private Health + Death in Service (x3 your salary)
Location: Abingdon, Oxfordshire

Looking for a role where Finance meets Supply Chain 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.

What We’re Looking For

This role would suit someone who already has experience in a purchasing, supply chain, ERP administration, accounts payable or operations support environment and can quickly become productive with minimal supervision.

You’ll need to enjoy working independently, following established processes and taking ownership of a high-volume administrative workload. This is not a role where you’ll be constantly directed day-to-day, so you’ll need the confidence to manage priorities, solve routine problems and proactively chase colleagues for the information needed to keep orders, invoices and transactions moving.

Essential

• Previous experience in a purchasing, supply chain, ERP administration, accounts payable or similar operational support role
• Strong Microsoft Excel and spreadsheet skills
• Excellent numerical accuracy and attention to detail
• Confident working with large volumes of data entry and data validation
• Comfortable following established processes accurately and consistently
• Able to work independently and hit the ground running with minimal training
• Confident communicating with colleagues at all levels of the business
• Comfortable persistently following up and chasing stakeholders for information, approvals and updates when required
• Strong organisational skills and the ability to manage multiple priorities simultaneously
• A proactive, self-sufficient approach with a willingness to take ownership of tasks

Desirable

• Experience using WinMan ERP, or a similar ERP/MRP system such as SAP, Oracle, Epicor, NetSuite or Microsoft Dynamics
• Understanding of purchasing processes, purchase orders, goods receipting and supplier management
• Experience processing supplier invoices and reconciling transactions
• Previous experience supporting both Supply Chain and Finance functions
• Experience maintaining accurate inventory, purchasing or operational records within an ERP system

A Note About This Role

We’re keen to be transparent about the nature of the position.

This role is ideal for someone who enjoys structured work, maintaining accurate records, processing transactions, and ensuring data quality within business systems. A significant proportion of your time will be spent entering, checking and validating information within our ERP and finance systems.

Success in this role comes from being thorough, organised and persistent rather than constantly seeking new projects. You’ll enjoy this opportunity if you take pride in accuracy, process compliance and keeping the business running smoothly behind the scenes.

While you will gain exposure to both Finance and Supply Chain activities, this is not intended to be a fast-track management or leadership role, and progression opportunities are likely to be limited. We are therefore looking for someone who enjoys this type of operational work and is motivated by doing it well rather than viewing it as a stepping stone to another position.

What You’ll Be Doing

• Manage the accurate processing of supplier invoices and purchasing transactions
• Maintain data integrity within WinMan and other business systems
• Create, update and validate purchasing, inventory and supplier records
• Follow up with engineers, managers and other stakeholders to obtain missing information and approvals
• Resolve discrepancies between purchase orders, goods receipts and supplier invoices
• Produce and maintain accurate records and audit trails
• Support the smooth operation of the Supply Chain and Finance functions through accurate and timely administration
• Help improve process efficiency and data quality as the business grows

Interested?

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

Location and work pattern:
All of our new UK team members are asked to work on site here at Abingdon during their first three months with us. We offer flexible, hybrid working where possible upon completion of probation. This tends to be limited to Friday’s due to the nature of the role which requires access to secure, onsite systems.
