• Hands-on approach to work: the ability to simultaneously handle multiple tasks, maintain focus, and effectively meet established deadlines.

• Interest in guiding teams, managing processes, and nurturing talent.

• Fluency in English; knowledge of Dutch preferred but not mandatory.

Desired skills:
