Impact Workers


CLOSED – Freelance Product Marketing Manager – Mobile App

About the role

Our mission is to bring people together to turn the tide on ocean plastic. It’s our belief that we don’t need a handful of people doing sustainability perfectly, we need millions doing it imperfectly. We have big plans and ambitions and have some great backing behind us – Ocean Bottle is made up of a lean but growing team and this is an opportunity to come join a brand that is going to change the world for the better.

Since launching in January 2019 Ocean Bottle has shipped hundreds of thousands of units to 88 countries and partnered with brands including Pangaia, Red Bull, Universal Music, Golden Globes through to Ed Sheeran. We have collected 7,639,660 kgs of plastic and improved livelihoods at the same time, because whether at home or further afield, environmental justice is social justice. We are proud of our diversity policy and it’s our belief that better ideas come from a more diverse team and that the ocean needs all of us. Our work is driven by our impact pillars, which we put front and centre to what we do: Ocean Health, Social Good, Closing the Loop, and Climate Action. By 2025 our goal is to prevent the equivalent of 7 billion plastic bottles from entering the ocean. Will you help us get there?
