Advancement Coordinator

At A21, we are driven by radical hope—the kind that believes slavery can end in our lifetime. We are a nonprofit organization working to abolish slavery everywhere, forever. For over 17 years, we’ve stood on the frontlines of freedom, rescuing people from human trafficking and walking alongside them through the journey of restoration. We believe that in a single moment, a number becomes a name, a tragedy becomes a victory, and belief becomes action. Freedom is our goal—for every human being on the planet.

We’re looking for a proactive and passionate Advancement Coordinator to join our UK team. This role is central to the success of our operations, donor relationships, and campaign initiatives. You’ll provide key support across administration, donor engagement, marketing, volunteer coordination, and event planning. You’ll collaborate with our UK Advancement & Mobilisation team and global A21 offices to help bring powerful strategies to life—and ultimately move us closer to a world without slavery.
