Your impact

We're looking for a Senior Internal Auditor who is as sharp as they are bold. Someone who doesn't just run audits, but challenges how audits get done, helping us safeguard Mollie's assets and keep our operations sound as we scale.

As Mollie continues to grow, including our ambitions in the payments and banking space, this function plays a direct role in maintaining the standards of control, compliance, and risk management a fast moving fintech needs.

You'll join a small team of auditors who chose depth over breadth: fewer topics, deeper dives, real impact. As a senior member, you'll take full ownership of audits from start to finish, bringing a fresh perspective and genuine enthusiasm for using AI to make audit work sharper and faster.

What you'll ship

  • Lead and execute internal audits across the whole company, including finance, operations, technology, and compliance.

  • Develop and implement audit plans, including risk assessments, using innovative tools and techniques such as AI.

  • Conduct in-depth reviews of processes and controls to identify risks and areas for improvement.

  • Prepare clear, concise, and insightful audit reports with findings, recommendations, and follow-up actions.

  • Collaborate with management to implement corrective actions and ensure risks are effectively mitigated.

  • Contribute to and help evolve the team's AI powered audit platform and tooling.

  • Stay current on relevant auditing standards, regulations, and best practices, and continuously explore new audit methodologies and technologies.

What you'll bring

  • A Master's degree in accounting, finance, or IT auditing, with relevant certifications such as RA, RE, RO, CIA, or CISA considered a plus.

  • A minimum of 7 years of experience in internal or external audit, ideally within a Dutch regulated financial institution.

  • Proven ability to lead and execute complex audits, from planning through fieldwork to reporting.

  • A passion for innovation, backed by a track record of developing and implementing new audit approaches.

  • Strong communication and interpersonal skills, with the ability to engage effectively with all levels of management.

  • Ability to work independently and as part of a team in a collaborative, fast paced environment.

  • As a senior team member, the ability to take full ownership of an audit from start to finish.
