Ruby on Rails Web Developer

We need a Ruby on Rails developer to join our Rails team of 3 existing members. The website facilitates basic user registration, login, facebook connect, social sharing of posts, html template integration (completed html provided by us) ajax updates of real time data, paypal basic donations & bitpay integration (bitcoin), and a basic API to provide data to JSON&real time updating flash/js widgets on the site. We will provide the complete specifications during the interview process. We do already have an existing Rails project that you will be team building on, however we are also open minded to allocating specific parts of the projects The application is very light weight, as we have put most of the work into other database scripts running behind the scenes, properly formatting the database so all you need to do is retrieve data without reformatting it.
