What types of jobs are available at Adult Swim?

Leigh, Adult Swim is part of Turner Broadcasting. I suggest going to Turner's job site http://jobsatturner.com/. Input Adult Swim under Advanced Job Search/Enter Search Terms and see what jobs are available. More importantly, you want to see what the qualifications are for the job you desire. It is also good to contact professional organizations dealing with animation such as Women in Animation http://www.womeninanimation.org/. They should be useful resources to tell you how to develop a career in production animation.
