Currently, we’re looking for an Internal Auditor. 

As an Internal Auditor, you thrive in a dynamic environment and act as a trusted voice across the organisation. You look beyond the surface, ask the questions that need to be asked and translate your insights into practical, forward-looking recommendations that support Triodos Bank’s mission. You understand what good looks like in today’s rapidly changing digital environment and are motivated to build your expertise further.

Internal Audit supports the Board, Audit Committee and senior management by providing independent assurance and advisory on governance, risk management and internal control.

• Identify opportunities to improve Internal Audit policies, guidelines, methodology and digital ways of working.
• Contribute to the annual audit planning process, bringing insights from your expertise, data analysis and developments observed across the business.
• Build familiarity with different business areas—including products, sectors and specialist domains—while deepening your own technical skillset.
• Apply and share your knowledge across teams, supporting colleagues through collaboration, coaching and insights.
• Engage constructively with stakeholders at operational and tactical levels, including Heads of Departments, project teams and business units.
• Build and maintain professional relationships across Triodos Group, including branches and support functions.

What you will bring

Your unique potential and your values matter to us most. We look for people who are self-aware and who think in a holistic way, always conscious of their impact on society, environment, and the economy.

To be successful in this role, you will:

• You have the technical grounding, analytical strength and professional maturity to deliver high-quality audit work while continuing to grow.
• 4–6 years of relevant experience in internal audit or related risk, control or compliance roles, ideally within banking, asset management or another regulated financial institution.

• Strong analytical skills with attention to detail, and the ability to identify meaningful improvement opportunities.
• Solid understanding of risk management, internal control and governance principles.
• Foundational experience with data analytics (e.g., Excel, SQL, Power BI/Tableau) and interest in applying analytics and AI to enhance audit delivery is highly desirable.
• Basic understanding of IT controls, information security and digital risks.
• Competent communicator, confident in engaging with stakeholders at different levels and presenting emerging observations clearly.
• Bachelor’s degree in auditing or another relevant field.
• Desirable professional qualifications (or working toward): ACA, ACCA, CIMA, CIA, CISA, CPA or equivalent.
• Excellent command of English; Dutch is a plus.
