Become part of a team that actively promotes the energy transition!
At greentech, we are team players and work closely together not only in our departments, but also across the group. With a distinctive, interdisciplinary mindset, extensive PV experience and high standards for ourselves, we successfully implement new projects, tap into new markets and continue to develop.
We support each other, make use of the short distances to the management, which is part of the team and is involved in everything that goes on, and talk our heads off sometimes, despite the hybrid work model and mobile office. What connects us is the concrete desire to personally contribute to a sustainable future, to make a difference. With this energy and the commitment of every single employee, we focus on the future, achieve excellent results – and satisfied customers. What is important to us as an employer:
Community
Flexibility
Co-design
Further development
What our employees say about greentech:
“At greentech, my role combines a diverse range of tasks — from creating PV designs and performing yield calculations to preparing building permit documents — with working in a great, reliable team. At the same time, I have the rewarding feeling of contributing to the energy transition through my work. This not only makes my job enjoyable but also deeply fulfilling. What I appreciate most is greentech’s feedback culture, which is built on mutual trust and appreciation. It creates an environment where you feel supported and can continuously grow in a positive way.”
Annika Richter
“I started at greentech with a focus on IT and industrial control technology, and over time, I had the opportunity to build my own team in this area. It’s exactly these development opportunities—combined with the chance to actively contribute to the energy transition through my work—that I value most about greentech. The diverse range of topics along the PV value chain ensures that the work remains varied and exciting. Additionally, the flexible working approach, including mobile office options, enables efficient and modern collaboration. What stands out to me the most is the high priority greentech places on employee satisfaction.”
Max Langkabel
“I deliberately chose a profession with a sustainable perspective. As a plant operator, I ensure that photovoltaic plants run trouble-free for a long time and reliably produce clean energy. At greentech, I work in a team in which we are all similarly motivated and work together every day to achieve what we believe in: a good future and the success of the energy transition.”
Alvaro Diez de Sollano Schivy
“Finance & Controlling is involved at all stages of the project development process and thus offers a broad and varied range of tasks. I like being actively involved in all these topics and contributing to their success. As a part-time manager, I succeed not only through my own competence and flexibility, but especially through a reliable team that trusts each other and can always rely on each other. What I find special is the spirit with which people work together across all areas of the company.”
Julia Ringleben
“At greentech, professional change and personal growth is possible through new tasks. In my case, I switched from plant operations to EPC. I like being in the company because the entire group wants to advance the sustainability aspect at all levels.”
