Are you excited?

We totally understand that, so are we! By joining us you can play an active role in changing the way the world views the ocean. Enthusiastic by the idea that your work will directly impact our products? Then we’d love to hear from you!

Research shows that while men apply to jobs if they meet ~60% of criteria, women and those in traditionally underrepresented groups tend to apply only if they check all the boxes. So, if you think you have what it takes but don’t meet every single point above, please still get in touch. We’d love to have a chat and see if you could be a great fit.

We value the diversity of our colleagues. People with disabilities are currently underrepresented in our company. We want to change that. For this reason, we are part of the Inklupreneur project and strongly encourage people living with disabilities to apply. We have the facilities and flexibility. We will support you in the working environment.
