Olark - YC S09 - Ann Arbor, MI (<a href="http://olark.com/jobs" >http://olark.com/jobs</a>) is looking for a DevOps engineer.
We're growing fast and we need somebody to help our infrastructure keep up.  We're profitable and you'd be #12 on the team.
You'd be doing infrastructure automation with puppet, helping us scale our messaging infrastructure so we can grow, and building tools to help us monitor our servers and our business.
For the curious, we use: Python, Ruby/Rails, Thrift, ejabberd, rabbitmq/amqp, mysql, mongodb, couchdb, redis, node, and more!
