We're a non-profit with a mission to provide a free, world-class education to anyone, anywhere. It's a big mission that we're taking on step by step. While we want anyone to be able to get a great education independently, we've been focusing a lot on trying to help teachers working in their classrooms (and a lot of teachers and parents are using Khan away from their classrooms right now!)
Our site has been built on Python 2 and Google App Engine for its first 10 years of existence. We're now in the midst of a rebuild in Go (still on App Engine).[1] Parts of that new Go-based infrastructure are already running in production.
To say that this is an exciting time for us would be an understatement, I think, but we continue to have working sustainably as an engineering principle. (Our principles are available publicly[2].)

haha everyone knows y'all! You guys are legends. Thanks for the kind and generous work you do over there!
Edit to add: speaking for myself and my perception of my coworkers... We just feel amazingly fortunate to have the opportunity to work toward our mission.
My academic life would be so painful without khanacademy and it'd be great to contribute to this.
We don't have internship openings right now. We generally do those interviews in the fall (for the following summer).
