• Department Overview
• In the insurance industry, the role and expectations placed on IT are growing increasingly significant. Within the IT Planning Department, we provide comprehensive support for Rakuten General Insurance Co., Ltd.'s business by executing, promoting, and managing the progress of development projects.
• Furthermore, as a non-life insurance company within Rakuten Group Inc. we play a vital role in providing security and peace of mind to Rakuten members through collaboration not only with other insurance group companies (such as Rakuten Life Insurance Co., Ltd.) but also with various other companies and services across Rakuten Group, Inc.

• Position:
• Why We Hire
• Cybersecurity threats are evolving daily, and to counter them, it is essential to constantly acquire the latest knowledge and technologies while deepening our expertise. At our company, we have established an environment where cybersecurity knowledge is shared across the entire organization, enabling continuous skill development.
• We are currently seeking individuals with deep knowledge and practical experience in the field of cybersecurity to further strengthen our organizational capabilities and pursue greater expertise. We welcome professionals who are ready to go beyond routine operations and engage in a wide range of tasks-including analyzing the latest threat trends, designing security architectures, and strengthening our incident response framework-to elevate our cybersecurity posture to the next level.

• Position Details
• You will collaborate with Rakuten Group, Inc. and various companies within the Rakuten FinTech Group to strengthen our cybersecurity posture and execute initiatives that support our growth strategy. Your primary responsibilities will include:

We also work with approximately 50 to 100 contractors from partner companies who primarily handle development tasks. 80% of our permanent employees joined us mid-career.
