Internal Auditor

 

Thunes is a global payments infrastructure company connecting businesses and financial institutions to enable fast, reliable and secure movement of money around the world.

As Thunes continues to grow and operate across an increasingly complex global and regulated environment, we are looking for an experienced Internal Auditor to strengthen our internal audit capability and provide independent assurance across the Group.

This is a senior, hands-on role with broad exposure across the organisation. You will develop and execute a risk-based internal audit programme, assess the effectiveness of our governance, risk management and internal control environment, and work closely with senior leaders to identify opportunities to strengthen the way we operate.

The role would suit someone coming from a Big 4 or similar professional services environment at Manager or Senior Manager level, who wants to move into an international fintech where they can have significant ownership, visibility and impact.

Key Responsibilities

Internal Audit & Assurance

• Develop and maintain a risk-based internal audit plan aligned with Thunes' strategic priorities and key business risks.
• Lead end-to-end internal audits across business functions, legal entities and geographies.
• Assess the design and operating effectiveness of key financial, operational, technology and compliance controls.
• Identify control weaknesses, emerging risks and opportunities to improve processes and governance.
• Produce clear, concise audit reports that translate findings into practical recommendations and actions.
• Track agreed remediation actions and work with stakeholders to ensure findings are addressed effectively and on time.
• Support targeted reviews and investigations where required.

Risk, Controls & Governance

• Provide independent challenge and assurance over the effectiveness of Thunes' risk management and internal control framework.
• Review key business processes and controls as the organisation continues to grow and evolve.
• Assess risks associated with new products, markets, systems and significant organisational change.
• Partner with Risk, Compliance, Finance, Legal, Technology and other teams while maintaining the independence expected of the Internal Audit function.
• Identify themes and systemic issues across audits rather than viewing findings in isolation.
• Support continuous improvement of Thunes' governance and control environment without introducing unnecessary complexity.

Leadership & Stakeholder Management

• Build trusted relationships with senior leaders across Thunes while providing credible and independent challenge.
• Present audit findings and recommendations clearly to senior management and relevant governance forums.
• Influence stakeholders to take ownership of control improvements and remediation.
• Bring an external perspective on leading practices in internal audit, governance and controls.
• Help shape and mature the Internal Audit capability as Thunes continues to scale.

Requirements

Experience & Knowledge

• Significant experience in internal audit, risk assurance or a closely related discipline, ideally gained within a Big 4 or other leading professional services firm.
• Currently operating at Manager, Senior Manager or equivalent level, with experience independently leading complex audit engagements.
• Strong understanding of internal controls, risk management, governance and audit methodologies.
• Experience auditing complex, international organisations across multiple functions and geographies.
• Financial services, fintech, payments, banking or another regulated-industry background strongly preferred.
• Experience assessing both financial and operational processes and controls.
• Good understanding of technology and data-related risks within a modern digital business.
• Experience presenting findings and recommendations to senior stakeholders.
• Relevant professional qualification such as ACA, ACCA, CIA, CISA or equivalent preferred.

Skills & Competencies

• Strong analytical skills with the ability to quickly understand complex businesses, processes and risks.
• Able to challenge constructively and confidently, including with senior stakeholders.
• Commercial and pragmatic - able to distinguish material risks from lower-priority issues.
• Excellent written and verbal communication skills, with the ability to turn complex findings into clear messages.
• Strong judgement, integrity and independence.
• Comfortable operating in a fast-moving, international environment where processes and structures continue to evolve.
• Hands-on and willing to personally lead work rather than relying on a large supporting audit team.
• Curious and proactive, with the confidence to question how things are done and identify better ways of working.

Why Join Thunes?

This is an opportunity to play a key role in strengthening the governance and control environment of a truly global payments business.

You'll have exposure across Thunes' operations, technology, finance, risk and commercial activities and work directly with senior leaders across the organisation.

Rather than stepping into a narrowly defined audit role, you'll have the opportunity to help shape how Internal Audit operates as Thunes continues to grow - bringing independent challenge, practical thinking and strong judgement to the risks that matter most.

If you're looking to move from professional services into a fast-moving international fintech where you can take real ownership and make a visible impact, this is an opportunity to do exactly that.
