For many people, work is the thing they invest the most time in throughout their lives.
There remains a lack of data to guide career decisions, and people continue to regret their job choices long after starting.
We engage with every individual's career, consolidate career data, and update the hiring market in an increasingly diverse world.
We utilize career data that has never been visualized before to support job seeking and hiring decisions.

ONE CAREER's Technology Development Department consists of the following 12 teams.
In addition to the Technical Development Department, the Information Security Office houses the Corporate IT and Security Team, and we collaborate closely to advance our work.

Engineering roles within the organization are as follows. Positions are determined based on the role one plays within the organization, and individuals are appointed to these roles.


At ONECAREER, we launched a project to enhance the productivity of our engineering organization in 2021.
By establishing a daily release system, we streamline the entire development flow (development to release), eliminating complexity in release operations and reducing the time until PRs are merged.

We continuously incorporate the latest generative AI tools while designing and providing learning opportunities such as study sessions and training.
