Our mission is to provide a world-class education to anyone, anywhere. We already have millions of students learning every month, and we're growing quickly.
Our students answer over 1.2 million math exercise problems per day, all generated by our open source exercise generation framework (http://github.com/khan/khan-exercises, http://ejohn.org/blog/khan-exercise-rewrite/), and Sal's videos have been viewed over 99 million times. We're just getting started feeding this data we're collecting back into the product to help our users learn more. If you're interested in data, analytics, and education, this is a dream gig.
Plus, it's one of the highest educational impact positions you can imagine.
We're hiring all types of devs -- mobile, frontend, backend, whatever you want to call yourself. Big plans ahead.
