About the Wikimedia Foundation

The Wikimedia Foundation is the nonprofit organization that supports Wikipedia, the other Wikimedia free knowledge projects, and our mission of free knowledge for every single person. We help bring new knowledge to people around the world, lower barriers to participation, and make it easier for everyone to share what they know. We do this by keeping the Wikimedia projects fast, secure, and available to all, protecting the values and policies that allow free knowledge projects like Wikipedia to thrive, building new features and tools to make it easy to read, edit, and share from the Wikimedia sites, and by supporting the communities of volunteers who make the projects possible.

At the Foundation, we build technology to help people everywhere access Wikipedia, across devices and in nearly 300 languages. We engineer privacy for our readers and editors so they can safely and securely explore Wikipedia. We create programs and initiatives to make Wikipedia freely available to more people in more parts of the world. We build new tools for the community of editors so they can continue to improve and grow Wikipedia. Roughly a quarter of our budget goes to supporting the community that make the site possible, including through grantmaking programs that enable volunteers and enrich the information on the sites.

The Wikimedia Foundation is an equal opportunity employer, and we encourage people with a diverse range of backgrounds to apply.
