Message from Our Team Members

Systems Division

Infrastructure Engineer

M.S.

Joined the company in April 2019

Currently, I am the Tokyo system manager and an infrastructure engineer. I make system plans, build cloud environments, and always support my members. Why did I choose SUN? Because when I say ‘I want to try it!’, this company always gives me a big chance. They believe in my passion. The experience of seeing an idea I proposed in an in-house contest actually adopted and brought to life was a moment when I truly felt I had grown as a person. At SUN, everyone is very close to each other. You can ask for help anytime. This friendly vibe is one of our best appeals. If you are even a little interested, please take the next step. We are looking forward to working with you.

Please make the most of your experience and aspirations at SUN.
We look forward to your application.
