Join a growing global business and help shape the future of international tax reporting

As Ardonagh's international operations continue to expand, we're strengthening our tax governance, reporting processes and controls across the Group. This is an exciting opportunity for a tax professional to play a key role in transforming our international tax reporting framework, supporting large-scale systems implementation projects and contributing to critical compliance initiatives including Country-by-Country Reporting (CbCR) and Pillar Two.

Reporting to the International Tax Controller, you'll work closely with finance and tax teams across multiple jurisdictions, supporting the delivery of high-quality tax reporting and compliance processes while driving continuous improvement and automation.

You'll support the end-to-end tax reporting cycle, review tax provisioning data from international entities, contribute to global compliance obligations and help embed new reporting processes and technologies across the organisation.

• Help maintain high-quality tax data and reporting consistency across the Group.

Stakeholder Management

• Act as a key point of contact for local finance teams across multiple jurisdictions.

• Communicate complex tax concepts clearly to non-tax stakeholders.

• Work closely with outsourced providers, local finance teams and the wider Group Tax function to ensure reporting and compliance requirements are met.

• Support responses to external audit queries relating to tax matters within the Group accounts.

Controls & Process Improvement
