Senior Tax Manager

About Thrivin

Thrivin is a fast-growing, multi-jurisdictional business with entities and operations across the Netherlands, Cyprus, and the United Kingdom, and an increasingly complex international footprint. As we scale across new markets and entities, tax has become a strategic function — central to how we structure operations, price intercompany flows, manage compliance risk, and make commercial decisions. We are looking for a Senior Tax Manager to own this agenda end to end and partner closely with Finance, Legal, and the wider business.

Role purpose

The Senior Tax Manager will be the in-house owner of Thrivin's global tax position, covering direct tax, indirect tax, cross-border matters, transfer pricing, and entity structure. The role combines hands-on technical leadership with strategic advisory: ensuring the group is compliant in every jurisdiction it operates in, while actively shaping how the business is structured and how transactions flow between entities. You will be the primary point of contact for external tax advisors, auditors, and tax authorities, and will be expected to operate with significant autonomy and judgement.

Key responsibilities

• Direct tax
• Own corporate income tax compliance across all group entities, including preparation, review, and timely filing of returns in coordination with external advisors.
• Manage current and deferred tax computations for statutory accounts and group consolidation, including effective tax rate (ETR) analysis and forecasting.
• Monitor legislative changes (including OECD Pillar Two, BEPS, and local corporate tax reforms) and assess impact on the group.
• Manage tax audits, inquiries, and correspondence with tax authorities.
• Indirect tax
• Own VAT/GST and other indirect tax compliance across all jurisdictions where Thrivin has filing obligations.
• Review indirect tax treatment of new products and business models, including place-of-supply analysis.
• Manage VAT/GST registrations, deregistrations, and ongoing reporting; ensure systems and invoicing are configured correctly.
• Support customs and other transaction taxes where applicable.
• Cross-border and international tax
• Advise on the tax implications of cross-border transactions, expansion into new markets, and new operating models.
• Manage permanent establishment risk, withholding taxes, and treaty positions; ensure correct application of double tax treaties.
• Coordinate global mobility and employment tax matters in partnership with People/HR where relevant.
• Stay ahead of international tax developments (Pillar Two, BEPS, EU directives, etc.) and translate them into actionable guidance for the business.
• Transfer pricing
• Own the group's transfer pricing policy: design, implementation, monitoring, and periodic refresh.
• Prepare and maintain transfer pricing documentation (master file, local files, country-by-country reporting) in line with OECD and local requirements.
• Set and review intercompany pricing for goods, IP, and financing; ensure intercompany agreements are in place and aligned with operating substance.
• Manage transfer pricing audits and benchmarking studies in coordination with external advisors.
• Entity structure and corporate transactions
• Maintain a clear, up-to-date view of the group's legal entity structure and tax attributes; advise on rationalisation, new entity set-up, and dissolution.
• Support corporate transactions (M&A, funding rounds, internal reorganisations) from a tax perspective, including due diligence and structuring.
• Partner with Legal on intercompany agreements, IP ownership, and substance considerations.
• External advisors and stakeholders
• Act as the day-to-day owner of relationships with external tax advisors across jurisdictions; scope work, manage budgets, and review deliverables critically.
• Partner with Finance, Legal, Treasury, People, and commercial teams to embed tax considerations into business decisions early.
• Present tax matters clearly to senior stakeholders, including the CFO, audit committee, and external auditors.

What we're looking for

Must-haves

• Qualified tax professional (CTA, ADIT, ACA/ACCA with strong tax specialism, or local equivalent).
• 5–8 years of relevant tax experience, ideally combining Big 4 / top-tier advisory training with in-house experience at a multinational or scale-up.
• Direct, hands-on experience with tax in the Netherlands, Cyprus, and the UK, and a strong track record on cross-border matters between these and other jurisdictions.
• Deep technical knowledge across direct tax, indirect tax, and transfer pricing, with substantive practical exposure to cross-border matters.
• Demonstrated ownership of a tax function or a significant pillar of one, including building or upgrading processes, controls, and documentation.
• Strong track record of managing external advisors and delivering through them rather than relying on them.
• Comfortable operating with ambiguity, building processes from scratch, and prioritising across competing demands.
• Excellent written and verbal communication; able to translate technical tax issues for non-tax audiences and influence senior stakeholders.
• Self-directed and effective in a fully remote setting, working across time zones.

Nice-to-haves

• Experience with Pillar Two readiness and implementation.
• Exposure to M&A, fundraising, or group reorganisations.
• Experience in a cross-border business model with multi-entity intercompany flows.
• Familiarity with ERP/finance systems (e.g., NetSuite) and tax engines.

What we offer

• A genuinely strategic seat — tax has direct visibility with the CFO and leadership team.
• The opportunity to shape the tax function as Thrivin scales, rather than maintain an existing one.
• Competitive salary, performance-linked bonus, and equity participation.
• Fully remote working, generous leave, and a collaborative, high-trust culture.
