• Follow up with colleagues on missing information, approvals or documentation.
• Identify practical opportunities to improve the quality and efficiency of our financial administration.

Your Profile

• Several years of hands‑on experience in bookkeeping, financial administration or a similar role.
• A relevant financial qualification such an MBO+/HBO degree in Finance, Accounting, Business Administration or equivalent practical experience.
• Strong practical understanding of general ledger bookkeeping, journal entries, AP/AR and reconciliations.
• Experience with Dutch financial administration is required.
• Experience with German bookkeeping or financial administration is an advantage, but specialist German tax knowledge is not required.
• Experience supporting VAT administration and month‑end activities.
• Fluent Dutch and professional working proficiency in English. German language skills are an advantage.
• Accurate, structured and highly detail-oriented in your work.
• Reliable and discreet when handling confidential financial information.
• Comfortable working independently, meeting deadlines and taking ownership of your responsibilities.
• Hands‑on, pragmatic and solution‑oriented.
• You enjoy bookkeeping and financial administration and are looking for a role where you can develop strong knowledge of the organisation and provide reliable long‑term support to the Finance team.

Joining Artinis & NIRx, you can expect:

• To support leading scientists in advancing the understanding of human physiology, pathology and pharmacology, and exploring new pathways for diagnostics and therapeutics to improve lives.
• A role with purpose, collaboration and autonomy in an agile organisation with flat hierarchies, quick decision-making processes and a shared‑leadership culture.
• A competitive compensation and benefits package, with employee wellbeing in mind.
• To work in a driven international team of engaged and enthusiastic colleagues with a make-things-better approach.
