Security Engineers are responsible for addressing security challenges that arise in large-scale and highly complex environments across various service platforms and global business operations. Their work includes analyzing and responding to vulnerabilities, threat events, and security weaknesses, as well as designing, implementing, and improving optimized security measures across different layers, including users, applications, networks, systems, data, and devices.
This team is a global engineering organization that designs security architectures in cloud environments and manages the development through operation of necessary solutions to enhance application security without slowing down service development.

Selection Process
All selection processes will be conducted in Japanese. |
| Re-Challenge System |
The Re-Challenge System lets applicants who do not pass the coding test retake it during a following round. We offer unlimited retakes until the end of the final round with the aim to lower the psychological barrier of the exam. Whether you've only recently started job hunting or are already determined to work at LY Corporation, we welcome anyone interested to take our coding tests.
*The Re-Challenge System also allows applicants to apply for different positions each round. (e.g., an applicant who takes the coding test for an Infra Engineering Expert during Round 1 can take the coding test for a Software Engineering Specialist in Round 2) |
