The ability to listen and communicate is necessary, as the job involves understanding customer requirements, making proposals to customers, and instructing programmers. People who like to talk with others. Also, people who are highly interested in cutting-edge technology, not just computers.

The job of a system engineer is to design the entire system by listening to the customer's requirements for what kind of work the computer is to do. The first step is "basic design," in which the engineer considers the system to realize the requirements based on what he/she hears from the customer. The next stage is "detailed design," in which the specifics of what methods and technologies will be used to create the system are determined. After this stage, the programmers must write a number of programs according to the blueprints, so they must create blueprints that are easy for the programmers to work on. The system engineer's important job is to connect the completed programs and check whether the entire system works according to the blueprints. If any defects or mistakes are found, they instruct the programmers to correct or adjust them. They are also responsible for maintenance and inspection of the system after it has been delivered to the customer.

Programming knowledge is required, so it is certainly a job for graduates of universities or technical schools with a science background. However, those whose last educational background was high school or who graduated from a university with a liberal arts major can also be successful depending on their efforts, making the most of their listening and communication skills. Some people start out as programmers to gain on-the-job experience and then move on to become system engineers.

No special qualifications are required to become a systems engineer. However, having a certification can be a proof of one's ability, and some companies offer "rewards" as a reward. There are several national certifications that can lead to career advancement, and there are also private certifications that certify skills related to the company's products.
