We're looking for a talented Tax Manager to join our Finance team and lead tax compliance and advisory activities across our international footprint.

This is a rare opportunity to step into a broad, autonomous role where you'll work across multiple tax disciplines, partner with senior stakeholders, and gain exposure to complex global tax matters within a growing technology business.

What you'll be responsible for

You'll own tax compliance and governance across Dext's global operations, including:

Corporate tax, VAT/GST, sales and use taxes, withholding taxes and employment taxes

Supporting transfer pricing, R&D tax credits and tax governance initiatives

Managing tax audits, enquiries and compliance risk

Approximately 20% of the role will involve supporting wider Group tax activities in partnership with the IRIS Group Head of Tax.

• Experience in corporate tax compliance
• Exposure to multi-jurisdictional tax obligations
• CTA, ACA, ACCA, CPA or equivalent qualification (or qualified by experience)
• Strong knowledge of corporate tax and indirect taxes (VAT/GST)
• Excellent stakeholder management and communication skills
• A proactive, organised and commercially minded approach

Experience gained within a Big 4, mid-tier practice, or an in-house tax function would be beneficial, as would experience within a SaaS, technology or high-growth business environment.
