A large amount of data is generated from these services every day, and currently over 250 petabytes of data have been accumulated. This data is considered a company-wide asset from the viewpoint of "Always Data-driven," which is one of the LINE STYLE.

The Data Platform Department, which is the recruiting department for this position, aims to democratize data (a state in which all employees can freely use data for business growth).
