The job of a storyboard artist is to check out and see how the story goes and see if it makes sense. Basically, you take the script and make the building blocks for the scenes of the animations but as rough drafts to start out.  You will be working with writers for each series and give any advice if needed.  However, you must also make sure the scripts for the story flow and communicate with the studio so they can work out the story and its flow. It would help if you have a lot of experience in this area.
