Research Engineer - Chomp (San Francisco, CA)

Chomp is building a social app discovery engine to help people find the apps they need and don't know they need now. We have been gaining significant traction on the iPhone platform since launching in January of this year by combining a unique search and recommendation experience for apps. As the most mature mobile app market, the iPhone and iPod Touch currently nets Apple more than 1 billion app downloads every 60 days. The strategy of the company is to expand to other platforms (Android, iPad, Web-HTML5) and thus build a destination portal for users to discover mobile apps. As apps become an increasingly favorable method with which users consume content on their devices, we believe we're building an important product within the app discovery space that extends to all app platforms.

We're currently applying topic modeling to app meta data to build a better search experience for users finding apps. That is, being able to search for apps by functionality or topic area as opposed to keyword based on the app title or description. Check out our recent press on MobileBeat.

The company is backed by a number of top tier VCs with a small and exceptional team that consists of folks from successful companies such as Google, YouTube and AdMob. We're looking for the early members of our research engineering team to build a team (rivaling that of Aardvark whom Ben Keighran , Chomp CEO advised, and was subsequently acquired by Google early in 2010) to help develop our recommendation and search engine that would allow consumers to discover apps on these various platforms.
