Help build a clean future

We seek passion and excellence

To succeed in our mission, we need to complete one of the most ambitious engineering projects on the face of the planet. Designing mega-structures capable of lasting in the harshest of environments is not easy. Cleaning up 70 % of the world’s surface is even harder, but it is a challenge we are motivated to overcome.

If you are a master problem solver and are willing to do whatever it takes to rid the world's oceans of plastic, we want you at The Ocean Cleanup.

Need a few good reasons to join the team?

  • See your work getting implemented months after designing.
  • Work on cutting-edge ocean engineering, ocean modelling and plastic pollution research.
  • Be part of a driven group of experts, who see the "impossible" as temporary.
  • Play a key role in launching the largest cleanup in history.

We bring the Silicon Valley culture to the Netherlands.

  • We move fast and iterate continuously; we build, test, learn, improve and repeat.
  • We value self-responsibility. We don’t register hours or number of holidays.
  • We have a flat organizational structure, giving you plenty of room to grow and take on more responsibility.
  • And, yes, we have a ping pong table. And we eat lunch together.
