Campaign Manager, Non-Profit & Social Impact

Only One runs campaigns that change minds and shape policy.

Our international team of experts specializes in strategic communications, movement building, and public advocacy to drive impactful ocean and climate policy worldwide.

Our philanthropically funded work focuses on supporting and amplifying the efforts of partners — both globally and in key regions — to restore ocean health and unlock the ocean’s potential as a climate solution.

Only Oneis a campaigning organization set up to protect the ocean and stabilize the climate. We build campaigns that move governments, industry, and institutions, working alongside partners, scientists, creators, and communities around the world.

Since 2020 we have grown to a team of 25, spread across multiple countries and time zones. We are small for the scale of what we take on, which means everyone here has real ownership and the work moves quickly.

We’re hiring a Campaign Manager to lead the day-to‑day execution of high-impact, fast‑moving advocacy campaigns that change ocean and climate policy. You’ll join a team of talented campaign managers as your peers, who are the engine of our advocacy work: translating strategy into results, building strong coalitions with diverse partners, and managing the moving parts of major initiatives to win measurable victories for the ocean and the communities that depend on it.

You’ll bring sharp policy and political instincts, a bias for action, and the ability to motivate and coordinate teams to push work over the finish line.

If you like taking a campaign strategy and working out what it takes to win, this role will suit you.
