Network engineers design, implement and maintain systems for companies. Because there is a fair amount of overlap in different IT roles, your exact job duties may differ from those of your counterparts at other organizations. You also may be expected to work different hours, outside of the regular 9-5 workday or more than 40 hours a week. But you will have the opportunity to hone your technical skills, increase your experience, work in a highly-regarded position, and stay up-to-date on current and future technologies. Suppose you are technologically-minded, have great communications skills, are a team player, and troubleshoot and problem-solve.
