A fast-growing international technology and media group is looking for an Interim Group Finance Manager to lead the first phase of its treasury and tax project.

You’ll also bring tax reporting together across markets and coordinate compliance and priority tax work with external advisers.

Reporting to the Group CFO, you’ll lead the first phase of the Group’s treasury and tax project. You’ll work directly with local finance teams to bring cash, debt and tax information together, build the models and reporting the Group needs, and put practical improvements into place.

What you’ll deliver

Treasury and working capital

• Give the CFO a reliable weekly view of where cash sits across the Group. Bring local balances and forecasts together in a rolling 13-week cash model, build a longer-term forecast for investment decisions and use both to plan funding and organise transfers between group companies.

• Work with local finance teams to understand what’s tying up cash in each business. Agree practical changes to improve working capital and take responsibility for seeing them through.

• Establish which bank accounts and corporate cards are in use, what they’re used for and who has signing authority. Track capital spend, borrowing obligations and interest payments so the Group knows what’s committed and when cash is needed.

Group tax

• Give Group Finance a clear view of its tax position in each market, including filing deadlines, risks and carried-forward losses. Build the expected amounts and timing of local tax payments into the cash forecasts.

• Work with local finance teams and advisers to keep corporate tax filings on schedule, gather the figures and supporting information for year-end tax reporting, and oversee open audits and assessments.

• Take the priorities already agreed under the Group’s tax strategy and work with Group Finance and external advisers to deliver them. Put the FY26 and FY27 transfer pricing arrangements into practice, document how they operate and help implement the tax framework for the Group’s next phase of growth.

About you

• Qualified ACA, ACCA or CIMA, or CTA with substantial group finance experience.

• Experience in group finance or financial control within a multi-entity, international business.

• Hands-on experience building cash flow forecasts and managing liquidity and working capital.

• Comfortable coordinating corporate tax compliance, year-end tax reporting and technical work with external advisers.

• Strong spreadsheet and modelling skills. You can pull together data from local teams, reconcile it and use it to produce clear reporting and identify actions.

• Able to take ownership quickly, follow up with local teams and keep work moving. NetSuite experience is a plus.

Contract details

• Six months, full time, with an immediate or short-notice start.

• Central London hybrid working, with in-person attendance for key meetings.

• Competitive day rate. Outside IR35 on initial assessment.

• One-stage interview process, with interviews planned for next week.

• Must already be based in the UK
