MISSION TO METRICS

To rid the world’s oceans of plastic, we rely on people across the globe — supporters who donate, apply, partner, and help spread our message. In this internship, you’ll help us strengthen these connections: making it easier for people to find us, support us, and stay engaged through every digital touchpoint.

“At The Ocean Cleanup, things move fast — our technology evolves, our story evolves, and so do the ways we engage our supporters. You’ll get to experiment, learn, and make a real impact along the way.” – Erika Träskvik, Head of Digital Marketing

RESPONSIBILITIES

As a Digital Marketing Intern, you will be involved in many new and ongoing projects to improve donor management, UX/conversion optimization, Google Ads, data analysis, email strategy, and much more. You will support the Head of Digital Marketing in executing these projects, gaining valuable hands-on experience from a non-profit organization with a strong global following. We take a data-driven approach to assess how these different efforts impact supporter numbers (conversion rate, churn rate, satisfaction score, etc.).
