Teams that create drawings, backgrounds, lettering, or other original graphics for commercial purposes work in graphic design. A senior graphic designer is often the leader of such teams, and he or she may have one or more junior graphic designers and other support personnel working with him or her. The senior graphic designer typically will be the member of the team who receives the various jobs to be performed and works out the parameters, requirements, and scope of the design. While the designer will normally perform much of this work, he or she will also delegate graphic work to other junior graphic designers on the team, typically suggesting edits to work and giving final approval before their work is submitted.In order to have a career as a senior graphic designer, a person typically must have extensive experience working in that field at junior or freelance levels. Most people interested in this job will seek out some kind of training after high school, especially education that involves the fundamentals of computer-aided drawing. Some of these designers attend art school or have an associate’s or bachelor’s degree in design or a related field. Senior graphic designers typically work regular business hours of the week, although projects approaching deadline can cause them to work extended hours.
