Tax Accountant

About the role:
As we scale rapidly across new geographies and business lines, tax has never been more important to how we operate.

This is a hands-on role with genuine breadth: from UK VAT to international direct tax, transfer pricing to R&D credits, you'll touch it all.

What you'll be doing:

• Own and maintain the global tax compliance calendar, tracking submissions across all jurisdictions and ensuring nothing falls through the cracks.
• Act as the primary liaison with our external tax advisors — managing relationships, keeping deliverables on schedule, and ensuring all workproduct arrives in a review-ready state for the Group Tax Manager.

• Work closely with advisors and the broader Finance team on statutory corporation tax provisions and returns, coordinating with the annual accounts and audit cycle.
• Prepare monthly tax accounting entries and ensure timely, accurate posting into the Group's financial records.
• Review intercompany recharges to ensure ongoing compliance with the Group's transfer pricing methodology
• Support the tax workstream of international expansion projects — including registrations, filings, and local compliance requirements as we enter new markets.
• Assist with R&D tax credit applications across relevant jurisdictions, working with technical teams to identify and document qualifying activities.
• Contribute to broader tax projects including corporate structure optimisation, transfer pricing methodology reviews, utilisation of tax losses, M&A activity, and intercompany debt financing.
