Hired | San Francisco, CA | Full-time | Software developers, data scientists, and product managers
Hired has done a great job in bringing efficiency and transparency to the job hunting process.  Top developers, data scientists, PMs, and sales professionals sign up on the site, and companies can give an offer to interview with upfront compensation.
Hired is a Ruby on Rails application, and gets deployed multiple times a day to Heroku.
We encourage developers that are interested in working at Hired to join the Hired platform.  That may mean that they end up finding a great job elsewhere, but that's great too.  Even our VP of Engineering was hired through the platform.
