Marketing Assistant - 12 month FTC

UNDO is tackling the greatest challenge of our time: climate change. We’re already one of the biggest carbon removal companies in the world, but this is only the start - we have ambitious plans!

In 2025, UNDO was named one of four global winners of the $100M XPRIZE Carbon Removal competition, giving further recognition and credibility to enhanced rock weathering (ERW) as a carbon removal pathway, and UNDO as a scientific world leader in this field.

In addition to our successful ERW operations, we’re now leveraging our expertise and underlying technology to deliver the UNDO Platform; the digital, financial, and scientific infrastructure that enables project developers around the globe to run scalable, bankable, and verifiable ERW carbon removal projects, generating billions of tonnes of verified CDR.
