RentMineOnline (San Francisco, based in the Presidio).
We're looking for our 3rd full-time rails developer.  We're changing the way that large apartment communities find and retain residents.
Why you should consider us:
    - define and take ownership over your projects
    - work at all levels of the tech stack
    - exposure to a profitable company with a small team
    - work with smart people (Duke and Stanford grads)
    
Our current stack is {git, slicehost, nginx, passenger, ree, rails 3, delayed_job, MySQL}.
We also use some amazon services {s3, rds, sdb} and have a fairly deep integration with facebook platform and linkedin.
We're in the process of moving from prototype to jquery, and will be doing the move to ruby 1.9 sometime in the coming year.
