Troubleshoot and bug fix Ruby on Rails application

I'm looking for an experienced Ruby on Rails Developer (3 years+) to work on an existing site that is deployed and live. The site is a custom application that connects employers with employees in a specific industry and then automates the process of job selection and application by letting the two parties communicate with each other through the system. The application currently has an error possibly with the routing or maybe with another area of the software which is causing the super-admin profile to be unable to action some items within the app. Technologies used in the system are as follows: # ruby 1.9.2p180 (2011-02-18 revision 30909) # Rails 3.1.5 # DPS Payment Gateway - [login to view URL] # Heroku (Staging and Production servers) # Github Any applicants must be able to clearly speak (and code) English. A large emphasis will placed on developers with BDD experience using test or rspec.
