Systems engineers design and coordinate large and complex projects known as systems. Systems Engineering is an interdisciplinary process that ensures that customer needs are satisfied throughout the entire life cycle a system. One example of a system is a jet airliner â€" and so are all of the airplanes owned by one airline, and all of the plans in one country. Other examples include water and food distribution networks, experimental manned space flights, and military defense programs. Systems engineers also work on telephone systems, electric power systems, and sewage systems. Systems engineering involves matching varied pieces together to make one cohesive whole. Engineers in this field interact with others in a variety of disciplines, depending on their particular industry, and the work to ensure that the individual parts can work together to perform a desired function. Starting salaries for Systems Engineers are around $75,000.
