How to Apply for Campaign Manager
at Only One
🏢 About Only One
Only One is a philanthropically funded campaigning organization dedicated to protecting the ocean and stabilizing the climate, with a nimble team of 25 spread across multiple countries. Unlike larger NGOs, it operates with a startup-like intensity where every team member has real ownership and campaigns move quickly. Working here means directly influencing ocean and climate policy on a global scale alongside scientists, creators, and local communities.
About This Role
As a Campaign Manager, you will be the engine of Only One's advocacy work—translating high-level strategy into fast-moving, measurable policy victories. You'll lead day-to-day execution of campaigns that target governments, industry, and institutions, while building and managing coalitions with diverse partners across regions. This role is ideal for someone who thrives in a remote, high-trust environment and wants to see their work directly contribute to ocean health and climate solutions.
💡 A Day in the Life
You might start your day with a virtual check-in with a partner in Europe, then dive into drafting a campaign brief for a new initiative targeting a regional fisheries policy. Later, you'll coordinate with the communications team on a rapid-response moment, and end by reviewing analytics from a recent action to inform next steps. Every day brings a mix of strategy, partner engagement, and hands-on execution.
🚀 Application Tools
🎯 Who Only One Is Looking For
- 3–5 years of experience in campaign management, advocacy, or movement building, ideally in environmental or climate policy.
- Proven ability to manage multiple fast-moving campaigns simultaneously, from planning through execution and evaluation.
- Strong coalition-building skills, with experience working with partners across different cultures and time zones.
- Excellent written and verbal communication, able to distill complex policy into compelling narratives for diverse audiences.
📝 Tips for Applying to Only One
Highlight specific campaigns you've managed end-to-end, including measurable outcomes (e.g., policy changes, public engagement metrics).
Demonstrate familiarity with ocean and climate policy issues—mention key frameworks like the UN High Seas Treaty or the role of blue carbon.
Show you can work remotely and asynchronously: give examples of how you've coordinated across time zones and used digital tools to keep campaigns on track.
Emphasize your experience with coalition building—name the partners you've worked with and how you managed diverse stakeholder interests.
Tailor your application to Only One's unique model: philanthropically funded, small team, and focused on amplifying partners rather than owning the spotlight.
