About the Team

As we scale the business, we are entering an exciting new chapter — strengthening governance, enhancing transparency, and building a world-class finance function that supports both operational excellence and public market readiness.

For that we are seeking to appoint a Group Financial Controller based in our headquarters in Amsterdam. As Group Financial Controller, you will play a central role in shaping and safeguarding the financial backbone of the company during a transformative phase. Reporting directly to the CFO and with regular exposure to the Audit Committee of the Board, you will be responsible for the full spectrum of financial governance across the Group.

You will lead a diverse and highly capable global finance team of 12 individuals consisting of controllers, group reporting specialists, internal control professionals, and tax experts. The team operates across multiple jurisdictions and time zones, working collaboratively with local management, external advisors, and our executive leadership.

About the Role

Your responsibilities include:

Financial Reporting

• Lead all group reporting activities under IFRS
• Ensure timely and accurate monthly, quarterly, and annual reporting
• Oversee IPO readiness from a reporting perspective, including prospectus financial disclosures
  

Manage external reporting obligations

• Monitor all balance sheet items and oversee the necessary impairment work
• Drive continuous improvement in reporting processes and systems
  

Internal Controls & Governance

• Design, implement, and maintain a robust internal control framework
• Lead IPO-related internal control enhancements (including SOX-like structures if applicable)
• Strengthen financial policies and procedures across 20 jurisdictions
• Ensure compliance with Dutch and international regulatory requirements
  

Tax Oversight

• Oversee global tax strategy and risk management
• Manage day to day the in-house tax compliance team
• Coordinate with external tax advisors across jurisdictions
• Ensure appropriate transfer pricing governance and documentation
  

Audit & External Stakeholders

• Act as primary liaison for external auditors
• Coordinate group and local audits across all operating entities
• Prepare materials and present to the Audit Committee
• Support Board-level reporting and governance requirements
  

Leadership

• Lead, mentor, and develop a high-performing international finance team
• Promote a culture of accountability, transparency, and continuous improvement
  

This is a rare opportunity to take ownership of the Group control function at a defining moment in our company’s history. You will have a direct impact on our scaling-up journey and on how we operate in the future. You will work closely with senior leadership, influence Board-level governance, and shape the financial standards of a truly international organisation.

About You

You are a senior finance leader who combines technical excellence with calm authority and a collaborative leadership style.

Your Experience

• Extensive experience in group controlling within an international, multi-entity environment

• Strong IFRS expertise
• Proven track record in IPO preparation and/or public company reporting
• Experience engaging with Audit Committees and Boards
• Solid understanding of internal control frameworks
• Experience managing global tax matters in coordination with specialists
• Background in telecommunications, infrastructure, or a similarly regulated industry is a plus

Your Profile

• Professionally qualified (e.g., RA, ACCA, CPA or equivalent) combined with an academic degree
• Structured, analytical, and detail-oriented
• High integrity and strong sense of accountability
• Comfortable operating in a dynamic, cross-border environment
• Able to balance precision with pragmatism
• A confident communicator who can translate complexity into clarity
• A leader who develops people and builds trust across cultures

Your Mindset

• You thrive in environments where standards are rising and complexity is real.
• You see IPO readiness not as a compliance exercise, but as an opportunity to build a best-in-class finance function.
• You combine resilience with diplomacy and are comfortable challenging constructively when needed.
• You enjoy building structure — but never lose sight of the bigger strategic picture.
  

We value professionalism, ownership, curiosity, and integrity. Our culture is ambitious but pragmatic — we work hard, support each other, and take pride in building something sustainable and lasting. This is both a strategic and hands-on role. You will be deeply involved in detail when needed, while also operating confidently at Board level.

If you are looking for a role that combines technical depth, international exposure, leadership responsibility, and strategic visibility — we would be delighted to meet you.
