Strong and inclusive management for the benefit of all

Our management team is comprised of men and women from a diverse and wide range of backgrounds. They all have one thing in common: extensive experience in their field of expertise, their ability to adapt to different situations and to work with employees from all walks of life.


Whether it's our board of directors, the departments of engineering, industrialization, business and marketing, finance, quality control, or even our production workshops, we only work with committed and experienced individuals. This management philosophy can also be found in our tech procurement, supply chain, and human resources departments.


However, we also gladly welcome interns and apprentices. We believe that young people represent the future, and that we can also learn from future generations.


Since we encourage diversity and merit, our managers build their teams based on individual skills, regardless of ethnic, cultural, religious, or social differences.
