\nOur engineers build systems that catch bad guys.  Using all available payment, user, and machine data, we have to separate legitimate credit card transactions from fraudulent in under 400ms.  That means doing just-in-time mash-ups of internal data with external APIs and reducing it all into a single score with a few critical insights for end-users.\n\nTo solve this problem, we're looking for world-class engineers who are eager to learn, adopt, and contribute to a reactive style of programming.  The position is for a backend engineer and will involve architecting and building scalable, event-driven fraud detection systems.
