Where are these developers at, and do they have decent working conditions and hours? $450k may not sound so glamorous if you work 80 hours a week in a hell hole. I looked at Jane Street in college but it seems they start their developers at $100k with no bonus, i.e., less than Google, Facebook, etc., even though Manhattan is even more expensive than the Valley.
