Game Engineer

Why Rakuten Games
Working in gaming industry has been a long time dream of mine, but transferring from non-gaming industry to gaming is not easy considering its unique positioning in Japan. To learn more about Japanese gaming industry I have been creating indie games and having it published by using afterhours, it was challenging yet meaningful time.
When I heard that Rakuten, one of the biggest EC companies in Japan, is about to enter the gaming industry, I saw the same spirit of challenge as I do - not afraid to challenge new things, dive into new categories and continuously improving. I truly believe that this environment will be able to provide me with lots of opportunities for learning and self growth.

Work at Rakuten Games
I am currently working as game frontend engineer and in charge of coding for front functions that are used by players, including UI, game effects etc… All front functions will give a direct impact on how users will react to the game so you can continuously improve the functions based on users’ feedback which makes this job unique and rewarding. To make the game more attractive, learning and introducing new technologies is also a part of my job.

Attractions of Working in Rakuten Games
Rakuten Games is a place where I find coexistence of both Japanese as well as international culture. Even as a Japanese with no abroad experience, I find myself blend into this working environment easily. Thanks to friendly, funny yet unique co-workers who selflessly share their knowledges and experiences I could continuously improve myself and products qualities.
Rakuten Games is an organization where you can overcome cultural and language differences and aim for the same goal together.

Your Dream in This Job?
I would like to create hit games that everyone knows!
