Electrical Service & Testing Technician (f/m/x) (Medium Voltage)

Nuventura has developed a new generation of electrical switchgear that is highly innovative and environmentally sustainable, which it now industrializes for scaling globally. While the company continues to develop new products with its R&D department, it now ramps up its production capability to meet growing demand for its already developed products.

While Nuventura's business model builds on licensing its technology to manufacturers around the globe, the company also supplies core components of the technology to such manufacturers. Additionally, Nuventura also manufactures full products for its home markets.
