Job Description

  • Design and operation of infrastructure such as AWS

■ Team Composition

Team composition: 40 (30 in the Philippines/10 in Japan)

There are 10 engineers working in Japan, including 7 foreign nationals. There are times when both English and Japanese are used, but there is no problem if you are not allergic to English, as there is a system in place for other team members to follow up on English.

We would like you to take the initiative in communicating requirements correctly to the development members in the Philippines while working with your hands, and to show leadership to the team by giving instructions from the design stage, conducting reviews, and so on.

In addition, as we increase the number of development members in Japan and expand the scope of development, you can eventually aim for a technical specialist or manager position.

We would like you to lead the development team technically first, but we would also like to hear about the future career you are aiming for.
