BackType (YC08) is hiring engineers to work on both the front and back end of our analytics product. We work mostly with Clojure and Python and use a mix of technologies from Thrift and Hadoop to Cassandra and graph databases. We're three people, we all code, and we work with TBs of data, manage a cluster of 100 machines, and build and scale products that serve hundreds of millions of monthly requests.
