Careers | The Ocean Cleanup

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

DATA-DRIVEN

We validate our work with science and numbers

TOP-DOWN

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

WORK WITH NATURE

Technology should be symbiotic with the environment

HIGHLY FOCUSED

Trying to do everything often leads to accomplishing nothing

STRIVE FOR SIMPLICITY

We avoid interdependency for faster iteration cycles

ITERATIVE

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

BUILD WITH EXPERTISE

… but not without questioning it

NON-PROFIT

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