Multiple FULL-TIME &#38; CONTRACT engineers in Carmel, IN (just outside Indianapolis)
Our engineers work on exciting and difficult problems - our goal is to answer any question algorithmically in realtime.  That's a BIG challenge, and it requires a lot of NLP, search, code optimization, and other fun work.
Our website is currently ranked #46 in Quantcast's US rankings, and earlier this year we answered our 2 billionth question, so there's plenty of traffic &#38; data to keep us busy.
We do most of our work in Java, but we also use Groovy &#38; Grails, Rails, and a handful of other tools.  Data-wise we use MySQL and Cassandra for OLTP, and primarily Hadoop &#38; HBase for OLAP.  We deploy to CentOS, and use git for SCM.  We use a Kanban SDLC.
We have a very collaborative open office environment in an open-air mall with easy access to places like Whole Foods, Starbucks, and a number of great restaurants.  Company lounge with an xbox, regular "office olympics", and plenty of other perks as well.
