I wanted to mention that Google’s search quality team is hiring. We work on everything from synonyms and spell correction to core ranking, UI changes, evaluation, and yes–even webspam. The sorts of people that do really well in Google tend to be smart, personable, can work well in teams or independently, get things done, and take initiative. It helps to have a healthy balance of theory as well as the pragmatic ability to build/launch real systems.
If you’re a smart engineer who wants to work on interesting problems across the scale of the entire web, why not reach out? drop us an email? Contact joinsearch at google.com to reach the recruiters in search quality directly. The best way to apply is to through our search engineering page. If you’re a great engineer who would like to work at Google in search, I hope you’ll apply! (The majority of people in the search quality group are based in Mountain View, California, by the way.)
