Job Description

In addition, although our working style is mainly to be stationed at the customer's site, we always have a day to return to the office once a month and provide an opportunity to communicate with all employees as a company.

Therefore, the team is strongly connected, and when there is a problem in the field, we can consult with each other and get a bird's eye view of our own technology.

In Detail

After being assigned to a project site, projects are basically carried out in teams of 5 to 10 engineers.

In order to ensure that each engineer's voice is reflected in his or her career, our sales staff and supervisors visit the project site once a week to conduct interviews.

We have an environment where you can feel free to discuss not only career-related issues, but also any concerns or problems you may have.

◎Examples of projects (Note: We have many projects that are 100% directly contracted by major domestic companies such as Softbank, Recruit, and AIJ).
