Wikia Inc - San Francisco
<a href="http://www.wikia.com/Hiring" >http://www.wikia.com/Hiring</a>
We are hiring engineers, design, product management and marketing.  We are looking for well rounded PHP developers, a MySQL DBA and a javascript specialist in advertising delivery platforms.
We have a great office in SoMa, a great culture (fun/creative/work-life balance++), an established, profitable and growing company (140 employees mostly in SF and Poznan, Poland). The SF engineering team is about 20 people. We are a large wiki hosting company (top 40 site in the US, 1B+ page views) based on Mediawiki.  In addition to just running our own thing, I'd like to find some people who are interested in re-inventing the wiki platform.  One of the down sides is working on mediawiki. :) One of the perks is being able to contribute code and ideas back to the Wikipedia Foundation.
Email me directly, or if you do go through our hiring page, mention HN or me in your cover letter and I'll definitely take a look at your resume.
