One Kings Lane (<a href="http://onekingslane.com" >http://onekingslane.com</a>) in San Francisco, CA.
We just moved into an historic warehouse building on 9th and Market downstairs from Twitter. We plan to add dozens of engineers, data analysts/scientists, and more (including non-technical roles) as we grow from &#62;$200M in revenue this year toward profitability: <a href="https://www.onekingslane.com/corporate/careers/tech/" >https://www.onekingslane.com/corporate/careers/tech/</a>
Our platform is barely a year old, mostly Ruby on Rails, Hadoop/MongoDB, Redis, Node.js, PHP/Zend Framework, jQuery, iOS/Objective-C. Our stack has enough variety that you can start contributing immediately with what you do know, while continuing to expand your skills into areas you want to know.
