What is a senior systems engineer?

A senior systems engineer is an IT (information technology) professional tasked with designing and maintaining network systems and security. Examples include large server or storage systems, computer networks, and mainframes. As a systems engineer, your primary duties are to oversee the daily operations of your facility and lead a team of engineers in designing new systems to replace old ones. You may work for a company that provides engineering services and solutions for other businesses, or you may be part of a large university or other institution's IT department. Skills needed for the career include the ability to work independently, leadership, and analytical problem-solving. A bachelor’s degree in electrical engineering or IT and significant experience in a lower systems engineering position are essential qualifications.
