仕事内容
Position Details
- The Security Architect acts as the strategic partner to our Security Engineering (SIEM/IR) team. While the Security Engineering team focuses on the "detect and respond" lifecycle, the Security Architect focuses on the "design and prevent" lifecycle. You will define the security blueprints, architectural standards, and governance models that our security engineers will ultimately monitor and defend. This role is a perfect fit for a senior expert with leadership aspirations who wants to influence the security posture of the entire Rakuten ecosystem.
- Unlike purely consultative roles, this position allows you to influence the Cyber Security Defense Department’s operational efficiency. By designing the standards that the SIEM/IR team enforces, you are directly responsible for reducing the "noise" and increasing the "signal" in our global security operations.
- Develop and maintain technical security standards, policies, and guidelines that provide the foundation for secure system development
- Lead security requirements and design reviews for new projects, ensuring that architectural flaws are caught before they reach production
- Collaborate closely with the SIEM & Incident Response team to translate real-world threat data (TTPs, IOCs) into proactive architectural changes and hardening strategies
- Mentor junior staff and collaborate with cross-functional stakeholders to build consensus on security roadmaps
- Drive the evolution of our security posture by integrating modern security patterns (e.g., Zero Trust, DevSecOps) into the SDLC
- Work in tandem with the Security Engineers
- Use findings from IR playbooks and SIEM detection use cases to update organizational security policies
- Ensure that as the engineering team develops new detection capabilities, the underlying system architecture supports visibility, logging, and automated remediation
