• Good command of Dutch and English; French is a strong advantage.
• Willingness to work in shift schedules (evening/weekend) and to travel within Belgium and neighbouring countries.

This role is ideal for technicians who enjoy working independently, taking responsibility and applying their technical expertise to support sustainable energy solutions.
