Finance Office – Client Service Specialist (Full-time, 1 year contract)

Join a school community where service, relationships and excellence matter

At the International School of Luxembourg, we believe that every interaction helps shape a family’s experience of our school.  Behind every invoice, payment plan, and account update is an opportunity to build trust, provide clarity, and support our vibrant international community.

We are looking for a Client Service Specialist who combines strong financial and administrative skills with empathy, professionalism, and a genuine commitment to helping others.  This is more than a billing role — it’s an opportunity to become a trusted point of contact for families and colleagues while contributing to the smooth and effective operation of a dynamic international school.
