Development Manager

Only One Collective | Flexible (Remote), Other


At the Only One Collective, our purpose is to turn the tide on ocean conservation by connecting people to urgent environmental issues and the communities affected by them, while identifying clear steps that will drive significant change. We do this through our two sister organizations: SeaLegacy and the Only One Platform. We focus on amplifying stories and campaigns that sit at the intersection of ocean health and social justice. We want to redistribute power by making the space we have available to a diverse group of storytellers and activists, prioritizing those whose experiences and narratives are marginalized and whose campaigns could use broad grassroots support to achieve meaningful impact.

The Only One Collective was first established in 2019, and today the organization has twenty full-time employees, across product, design, content, engagement. By partnering with other changemakers in the space, we aim to support innovative solutions that strengthen marine ecosystems and the communities that depend on them most.

The Only One Collective has a sizable existing community, including 10M followers across social media channels, an email list of ~300K, and The Tide, a growing community of ~4K monthly donors committed to supporting ocean solutions.
