What to expect:
We are looking for an Accounts Payable Manager to join IonQ's growing finance function in the Oxford, UK. This role will own the day-to-day running of accounts payable — ensuring bills are processed accurately and on time, payment runs are executed cleanly, and the AP ledger stays tidy and well controlled. You'll play a key part in a fast month-end, helping to close AP on business day 0 to support the wider finance team.
This is a hands-on role for someone who is process-minded and commercially aware, comfortable operating in a fast-moving, multinational tech and science environment. You'll partner closely with Procurement, Treasury and the broader Finance team, while continually looking for ways to improve and scale AP processes as the business expands.
What you'll be responsible for:
You will manage the full AP cycle, from bill processing through to payment. This includes processing bills during busy periods, managing payment runs to meet supplier requirements, and managing ad-hoc payments to employees, suppliers and partners.
You'll keep the AP ledger clean and accurate through regular reviews - chasing pro-formas, running AP ageing analysis and managing the AP balance sheet, including reconciliations and VAT checks. You'll also take ownership of supplier relationships: negotiating credit limits and payment terms, keeping supplier records up to date in NetSuite, and working with Procurement to manage those relationships day to day.
Key responsibilities will include:
- Processing bills and supporting a business day 0 AP close as part of a short month-end
- Executing payment runs and managing ad-hoc payments to employees, suppliers and partners
- Reviewing the AP ledger, running aging analysis and managing the AP balance sheet
- Carrying out VAT checks and AP balance sheet reconciliations
- Identifying efficiencies and areas of improvement across AP, partnering with Procurement on supplier management
Requirements:
You will have 5+ years of accounts payable experience in a fast-moving or high-growth technology or science company. You will be experienced in coding bills across various general ledger types, managing payment runs and resolving supplier queries, with a solid understanding of UK VAT compliance. You should also have experience working with cross-functional teams to resolve invoice discrepancies, monitoring invoice approval workflows and following up with budget owners to ensure timely approvals. You will respond professionally and promptly to vendor and employee queries regarding invoices, payments and account status.
You'd be a great with :
- Experience in a listed company environment with a business day 0 AP close
- SOX experience
- Familiarity with ZIP and NetSuite
- Experience with overseas VAT compliance
- Accounting qualification
