We seek passion and excellence

Our mission is to develop advanced technologies to rid the oceans of plastic. We need to complete one of the most ambitious engineering projects on the face of the planet. To succeed in our mission, we hire dedicated, fully focused and out-of-the-box thinking employees.

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.

Our values


We validate our work with science and numbers


We start by tackling the big problems and solve the smaller ones along the way


Technology should be symbiotic with the environment


We test often and fast – to learn as we go and adapt when needed


We avoid interdependency for faster iteration cycles


Trying to do everything often leads to accomplishing nothing


… but not without questioning it


The Ocean Cleanup is a project that has a strict deadline; once the oceans are clean, our project is complete

Job openings

Need a few good reasons to join the team?

  • See your work getting implemented months within months of initial design
  • Work on cutting-edge ocean engineering, ocean modeling, 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

  • Build, break, learn, and repeat: we iterate fast and continuously
  • We work anywhere, anytime.
  • Personal accountability is our culture (no time sheets or fixed number of holidays)
  • From (free) team lunches, to drinks on the terrace, to ping pong – we work hard, but we also enjoy downtime
