Planet Nerd has a great little video tour of Australia's largest mobile games developer, Firemint. Firemint has been around for about 8 years delivering games on over 60 different mobile devices. Because of short development timelines, working on mobile devices allows developers to quickly rack up credits over a number of titles, as opposed to console development where a developer with 3 years experience may only have one or two titles to their name.
Firemint is always looking for new talent, and a quick check of their website reveals they are currently looking for programmers, designers and artists. People trying to break into the industry will be interested to know that they are also willing to look at juniors with no game dev experience, provided you have an excellent academic transcript or a great demo of course.
