*ahem* the answer to your question is - be in the right place, at the right time and be very very lucky.
More seriously though, what exactly are you asking? How to get into art & design? Or what jobs are available for people with artistic skills?
In terms of that, arty types can get involved in all kinds of jobs from greeting card illustration to concept art for movies and videogames. Most seem to go freelance but there are very occasionally actual jobs available depending on experience.
