Mixpanel's mission is to help the world learn from their data. We've made it ridiculously easy to run extremely complex queries across massive amounts of data, all in real-time - our reports are literally to-the-second.
We're currently processing over 10 billion transactions per month from gaming, mobile, social, and e-commerce companies world-wide. This volume of data, and types of analysis we do, give us some uniquely interesting problems to solve: scaling, data integrity, building api's, availability, and data visualization.
Mixpanel is an equal opportunity/affirmative action employer supporting workforce diversity.
