IT Auditor (Interim, Part-time)
About the assignment
A leading public sector organisation in South Holland needs an experienced IT auditor to strengthen its audit function. You'll own the full audit lifecycle—from planning and execution to stakeholder reporting—covering critical systems like DigiD, Suwinet, and financial IT infrastructure.
This interim role carries real responsibility. You coordinate external and internal audits (ENSIA, year-end controls), oversee audit findings, and advise on emerging legislation (Cybersecurity Act, Data Processing Act). You're the central contact for regulators and internal stakeholders across multiple departments.

- Coordinate and oversee all audit obligations, including ENSIA and IT-audit for annual accounts
- Plan, organise and execute internal IT audits on critical controls (DigiD, Suwinet, financial systems)
- Assess and strengthen existing audit documentation and audit structure
- Prepare and deliver board-level reporting, regulatory submissions and correspondence to supervisors
- Manage external audit arrangements—from tendering through delivery and stakeholder alignment
- Monitor follow-up on audit findings and recommendations from previous audits
- Advise on new audit requirements under emerging legislation (Data Processing Act, PARTA, Cybersecurity Act)
- Contribute to integration of ISMS, Privacy Management System and GRC tooling implementation
