About the department and service
We develop and operate a platform specialized for businesses that use Rakuten Travel and various leisure services (horse racing, GORA, toto, lottery, etc.). Our mission is to improve the core of the services that support the business with our technical capabilities.
The Data Analytics Platform Section is in charge of analytical system platforms specialized for Rakuten Travel and various leisure services (horse racing, GORA, toto, lottery tickets, etc.). We use a wide range of knowledge and ideas to develop and operate the platform, which is used to analyze a wide variety of data in many different ways.
Rakuten Travel is the central and largest of Rakuten's various services, and when combined with data from various leisure services, a wide variety of data, including reservation data, purchase data, inventory information, partner information, and end-user activity history, continues to grow on a daily basis.
Our work is to utilize and analyze these data, promote cross-use among various services, and develop and operate platforms that support business decisions.
We are developing analytical ecosystems based on DWH (Teradata), which can accumulate and process large-scale data, and data lakes using Hadoop, as well as data input pipelines and real-time data processing using various OSS, automation of various operations, and BI to make analytical work easier for analysts. As an engineer, you will be exposed to a wide range of technologies and be involved in very challenging development.
In addition, there are only a limited number of companies that can actually handle "large-scale data" and there are few examples. It is sometimes necessary to work together as a team to tackle new technologies, which allows you to grow together with many product managers and development engineers. Therefore, you will be able to grow together with many product managers and development engineers.
Moreover, since we play a major role in keeping the products we develop running stably, we sometimes need to recover from failures in mission-critical systems or develop defensive measures to prevent their recurrence.
We are looking for people who want to acquire both offensive and defensive engineering skills through the development and operation of data analysis platforms.
