Careers

We are proud of the technology we pioneer, but even prouder of the people behind it.

Our team is united by a shared mission: to leave water and the world better than we found it by intercepting microfibre pollution at the source. Every innovation we develop, every challenge we solve and every partnership we build is driven by that purpose.

Guided by our values of Impact, Protect, Unite, Solve and Urgency, we bring together expertise, determination and a commitment to action. We believe that solving one of the world’s most widespread forms of pollution requires collaboration, bold thinking and the pace to drive meaningful change.

As the last line of defence between microfibre pollution and the water we leave our children, we take our responsibility seriously. That’s why we continue to pioneer filtration technology that stops the impact of microfibres from factory to final wash, helping move us closer to our vision of a world free from microfibre.

Our people are the reason we can turn that vision into progress every day.

We are building a community of ambitious, mission-driven problem solvers.

United by a shared commitment to leaving water and the world better than we found it, our team combines expertise, curiosity and determination to tackle the challenge of microfibre pollution at scale.

We create an environment built on trust, where people are empowered to think independently, challenge convention and develop innovative solutions with measurable impact. Diverse perspectives and experiences strengthen our ability to solve complex problems and accelerate progress towards a world free from microfibre pollution.

We’re always interested in hearing from people who share our sense of purpose and believe engineering, design and technology can play a meaningful role in protecting the environment.

Our team is primarily made up of engineers and designers from mechanical engineering, product design and related disciplines, working together to pioneer filtration technology that stops the impact of microfibres from factory to final wash.
