Trulia - San Francisco, Full time, (H1B transfers)
Innovation happens every day.  <a href="http://youtu.be/YJHsr2ep1cw" >.
Trulia is one of the largest real estate search platforms in the United States with over 40 million visitors across our platform every month. We're solving interesting problems and building cool things in nearly every software engineering discipline.
We've got lots of interesting and large scale projects to tackle including:
Building our next generation of APIs (for both internal and external consumption)
Creating new mapping and data visualization experiences
Improving our web experience using a JS MVC framework and our new OOCSS library (similar to Bootstrap)
Innovating on our top ranked mobile apps
Diving deep into the terabytes of housing and user data we have in order to tailor custom experiences for our users
Our core web stack is a pretty traditional LAMP stack, but we use a ton of other technologies as well including: Python, Java, Hadoop, Solr/Lucene, CouchDB, Backbone (though we are currently exploring other JS frameworks as well), d3.js, Sass, Git, and a whole lot more.
I've been an engineer at Trulia for over four years now and can honestly say that it is a really fun company to work for. There's a great culture of letting people run with projects that really interest them and drive the entire engineering organization forward.
The perks are fantastic: 
great health benefits
unlimited vacation
monthly transportation and "well being" allowances,
lots of happy hours
kegs on two out of three floors
stocked kitchens, 
quarterly hack weeks to name a few
