..CO2-neutral on the outside and open cooperation on the inside

Hoarding knowledge and working behind closed doors does not exist with us – although we know how to keep confidential information.

Our corporate culture is based on partnership, mutual respect and also a cozy chat over a ‘Gipfeli’ and a good coffee or tea.

Nevertheless, focus and concentrated work are key in our everyday work – we not only love efficient technologies.


…rather thumbs up than sore muscles in the raised index finger

When small mistakes make us smarter, they are already part of the solution!

Should something go wrong, we will look for the cause together in order to remedy it as quickly as possible. We’d rather be happy about what we have achieved together than to look backwards to seek out the guilty.

Our technologies set standards in their markets and their development should be fun. Open feedback helps each other and constructively in the team.

Our goal: having fun growing together and breaking the limits.


…is not enough for us, if there is still room for improvement

Our DNA is continuous research and development of pioneering technologies and their entrepreneurial implementation.

We combine open thinking with long-lasting experience and youthful creativity.

We are convinced that innovations are key to solving existential problems as long as they are based on natural cycles and sustainability.

GreenOcean wants to make an active contribution to a worth living ‘blue planet’ for our next generations.

…direct contact and
flat hierarchy

Your application will go straight to your potential future team.

We will contact you within a few days and give you feedback on your application.

If the curiosity about each other has grown after the first contact, we can make an appointment directly to get to know each other personally.


…as flexible as our getting to know each other becomes pleasant

We invite you flexibly to a personal meeting at one of our locations, halfway or in our home office (by video or phone).

In the first half hour we would like to find out as much as possible about you. Afterwards you can take your time to ask us holes in the belly.


…there is nothing better than experiencing each other personally

We would like to give you an idea of who we are and get to know you as well as possible. To this end, we initially consider two discussions to be important.

In the further process, we would like to bring you in direct contact with your potential team. Ideally, we could hook you up with us for a day or two.

We agree flexibly on how we can make this possible in the current situation.
