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.

• 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.
