International Tax Lead

About the team

SumUp's Finance Tax team sits at the heart of a fast-growing global fintech, managing direct tax and transfer pricing obligations across more than 35 entities.  As International Tax Lead, you'll be the dedicated owner of SumUp's cross-border tax perimeter, a domain that spans permanent establishment monitoring, Pillar 2 / GloBE, double tax treaty application, EU Directives, and public Country-by-Country Reporting. This is a rare opportunity to build and own a critical international tax function from the ground up, at a company navigating significant regulatory complexity and an ambitious growth trajectory.

What you'll do

• Own SumUp's permanent establishment monitoring framework, maintaining a live risk register across all relevant jurisdictions, assessing exposure, and managing registration and filing obligations where a PE is confirmed or probable
• Lead the technical application of Double Tax Treaties, the Multilateral Instrument, and EU Directives (Parent-Subsidiary, Interest & Royalties, ATADs, Mergers, and the EU Minimum Tax Directive) — advising internal teams and documenting positions to support audit defence
• Act as the technical authority on Pillar 2 / GloBE — certifying entity-level GloBE income and adjusted covered tax calculations, monitoring QDMTT obligations, advising on Safe Harbour eligibility, and coordinating data inputs with Accounting and Controlling
• Own the design and content of SumUp's Public CbCR disclosure — ensuring accuracy, internal consistency, and strategic consideration as the EU Directive rolls out across member states
• Co-own transfer pricing strategy and benchmarking methodology alongside the Global Head of Tax and the Senior EU Tax Manager, acting as technical reviewer on complex TP positions
• Serve as the primary cross-border tax reference point for internal stakeholders across Legal, Treasury, Finance, and Product, and manage relationships with specialist international tax advisors

You'll be great for this role if…

• Proven experience in international tax in a multinational environment, with a background spanning both advisory (Big 4 or specialist boutique) and in-house roles
• Strong technical knowledge of PE monitoring, OECD Model Convention, DTT networks, MLI positions, and EU Directives including ATADs
• Hands-on understanding of Pillar 2 / GloBE rules — including income calculations, covered tax calculations, QDMTT, and Safe Harbour analysis
• Ability to read, challenge, and discuss financial statements independently, with a solid accounting foundation and familiarity with the interaction between management and statutory accounts
• Comfort working across multiple jurisdictions simultaneously, with the project management discipline to build frameworks while keeping live compliance obligations on track
• Fluency in written and spoken English, with an ACCA or equivalent professional qualification
