The company I work for when I’m not working for the Mozilla Foundation, Data Connection, is looking to hire four to six software developers (either new graduates, or people with existing experience) at their offices in Enfield, North London, where I work.
I can’t promise you would get to work on or with Free software, but you would get to work with smart people for a company who are very good to their employees, and have a great culture of technical excellence. The fact that they are such a good company to work for is one of the reasons I’m currently attempting to do two jobs at once. ;-) You don’t have to be a graduate in a numerate discipline – we already have classicists, linguists and others.
If you’re not a UK citizen, that’s not necessarily a showstopper, but this post is aimed mostly at UK residents.
