Join Us in Powering a Cleaner Future

We are a small, dedicated team where each of us takes ownership of their area of responsibility and makes a meaningful contribution to the success of our company. With sustainable projects and the clear goal of a circular battery economy, we are driving the energy transition forward. Become part of our mission and help us shape the energy future!
Taking responsibility with us means actively contributing from day one and taking matters into your own hands. Ownership isn’t just a buzzword here — it’s how we work every day. Everyone can bring their own ideas to the table, drive projects forward, and deliver real results. Teamwork thrives in our flat hierarchies — we all pull in the same direction and bring our projects to success together.
If you’re ready to take ownership, make an impact, and be part of a team that truly sticks together, then you’ve come to the right place.
