About Tumblr 

Tumblr launched in 2007 with the belief that people need for a place to say what they want, be who they want, and connect over what they love. Now, 10 years and hundreds of millions of blogs later, we continue to build out Tumblr as a platform for free expression, individuality, and human connection.

From art to music to dank memes to social justice, we’re proud to serve all the subcultures that call Tumblr home, and even more proud of the impact they’ve had the world. No matter what department you work with here, you’ll be working to give our users a voice, and to make that voice heard far and wide.

We know—this sounds like a big task. It is. That’s why we need smart, humble, funny people to keep Tumblr running and growing. We’re big enough to give you the resources you need and still small enough that you can work on things that matter. Come work with us.
