We’re looking for a seasoned infrastructure engineer with Hadoop experience, someone who can both implement elegant solutions to Big Data problems and lead by example. You’ve architected highly-scalable, distributed systems efficiently using open source tools -- and maybe even contributed to some.  You’re well versed in the challenges of dealing with petabytes of data on a daily basis and the opportunity to crunch billions of social signals a day excites you.
Problems we’re working on:
-Scalability and Infrastructure: Building infrastructure to collect, store and process hundreds of millions of social interactions per day
-Real-time systems: Real-time data infrastructures to process large volumes of data
We're also looking for some seriously-talented operations engineers to help us create cutting edge systems and tools to manage, maintain and monitor all aspects of the Klout production, staging, and development environments.  Our environment is an intense combination of modern software and tried and true technologies including and leveraging Hadoop, Hbase, MongoDB, ElasticSearch, MySQL, HAProxy, redis, memcached, Node.js and Scala.  We'll challenge your scalability chops with our high volume consumer site traffic coupled with the Big Data challenges of processing over 2.7 billion data signals a day for over 300 million users on multiple petabyte clusters.
