Senior Tax Manager

Join Thrivin and Shape a Global Tax Function

Thrivin is a rapidly growing international business with operations and entities across the Netherlands, Cyprus, and the United Kingdom, alongside an expanding presence in additional markets.

As the business grows in scale and complexity, tax is no longer simply a compliance requirement — it is a core strategic function. It plays a critical role in how we structure our business, manage intercompany pricing, navigate international regulations, and support commercial decision-making.

We are now seeking an experienced Senior Tax Manager to take full ownership of Thrivin’s global tax agenda and work closely with teams across Finance, Legal, Treasury, People, and the wider business.

This is a high-impact, in-house leadership role for a tax professional who combines strong technical expertise with commercial judgement.

As Senior Tax Manager, you will oversee Thrivin’s global tax position across direct tax, indirect tax, transfer pricing, international tax, and entity structuring. You will ensure compliance across all jurisdictions while also helping to shape how the business grows, operates, and transacts internationally.

You will serve as the main point of contact for external tax advisors, auditors, and tax authorities, and will be trusted to operate with a high degree of autonomy, ownership, and strategic influence.
