How to become one

No particular education or qualification is required to start, but many have a university degree or master's degree, and some are kosen (college of technology) graduates.

Although not needed to start, some people sit the Fundamental Information Technology Engineer Examination or Applied Information Technology Engineer Examination while working. New graduates take 3 to 4 months of induction training after joining, learning business skills for working life and the digital transformation (DX) knowledge systems engineers need. After training, you are placed in a team and spend about 2 years building practical and applied skills through on-the-job training in development. After that, you take training on topics needed for your work. At first you handle part of a development project, and generally by around your third year you can write detailed designs on your own. By around your fifth year you can handle a whole development project, including basic design. Many people become systems engineers straight from graduation, but some first gain experience as programmers. Experience and knowledge from other industries can also be used, so quite a few people move from other industries. As a career path, once you can analyse a client's business and do the basic design of information systems, you lead development teams and manage the work. After that, some are given large system projects and become project managers or product managers and move into management, while others use their technical skills in sales, become specialists in areas such as security, or work as IT consultants. To become a systems engineer you need knowledge of information systems technology and detailed knowledge of the client industry's work. To move development forward you also need the vision to see the whole picture, the ability to find and solve problems, flexibility to respond to change and management skills to drive projects. You deal with and exchange views with many people of different ages and backgrounds inside and outside the company, so communication skills are very important and teamwork is strongly needed. You need broad curiosity rather than staying within your own field, gathering information, learning new technology and related knowledge yourself and taking on new challenges. You also need to deal calmly with problems and pressure.
