Working at Sialtech

Within our company there is a collegial, informal atmosphere with plenty of room for personal initiative. Sialtech has more than 30 employees who work on projects independently or in small teams. We have a diverse team, of which two-thirds have been in service for more than 10 years. That says enough. For all our employees, we seek the right balance between personal responsibility and guidance.

We continue to grow as company and are therefore always looking for new talent for different positions. Will you join our team?
