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:
- Security Policy & Regulation Development: Reviewing and improving internal security policies and regulations based on the latest threat landscapes and regulatory requirements

Work Environment
Information Technology Division is composed of two teams, the IT Development Department and the IT Planning Department, with a total of 34 permanent employees. 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. Many come from outside the non-life insurance industry, so we provide full support for those without prior industry experience.

- Fundamental knowledge of information security (Information Security - Management Systems (ISMS), types of threats, countermeasure technologies, etc.)
