Department Overview

The Cyber Security Defense Department (CSDD) is responsible for safeguarding all Rakuten companies and users from cyber threats, ensuring the security and integrity of Rakuten Group's global internet services. We oversee all aspects of both Secure Development and Security Operations for services developed within the group, with dedicated security teams and operation centers strategically located in key regions worldwide.

Position Details

We are seeking an experienced leader to establish and scale Rakuten's Public Cloud Security program across multiple businesses and public cloud environments.
This role is responsible for defining the strategy, operating model, and roadmap for Public Cloud Security, working closely with the Cloud Center of Excellence (Cloud CoE), development teams, and other technology stakeholders throughout the organization.
The mission of the Public Cloud Security team is to provide centralized visibility, governance, expertise, and automation for cloud security while enabling development teams to maintain ownership and accountability for remediation within their respective services.
As the Manager, Public Cloud Security, you will drive the adoption of market-leading and/or internally developed security solutions, establish scalable security guardrails, expand security automation, and improve the organization's ability to identify and respond to security risks at scale. You will focus on reducing manual security operations by integrating security directly into cloud platforms and engineering workflows, allowing development teams to address security findings efficiently while maintaining enterprise-wide visibility into risk and compliance.
This role requires strong leadership, technical expertise, and the ability to influence stakeholders across multiple organizations while balancing security, operational efficiency, and business agility.
Define and execute Rakuten's Public Cloud Security strategy, vision, and roadmap
Establish a scalable cloud security operating model that supports business growth and cloud adoption across multiple organizations
Build, lead, and scale a high-performing Public Cloud Security team while fostering a culture of automation, engineering ownership, and continuous improvement
Drive collaboration and alignment among the Cloud Center of Excellence (Cloud CoE), development organizations, and business stakeholders
Define long-term security investment priorities and technology roadmaps for cloud security capabilities
Lead the adoption and operation of market-leading and/or internally developed cloud security solutions
Build security capabilities that provide continuous visibility into cloud assets, security risks, compliance status, and remediation activities
Drive security automation initiatives to improve detection, response, governance, and reporting
Establish security guardrails and self-service security capabilities that can be consumed by development teams
Reduce manual security operations by integrating security controls into cloud platforms, engineering workflows, and software delivery processes
Promote security-by-default and security-by-design principles across public cloud environments
Define and maintain public cloud security policies, standards, controls, and governance frameworks
Establish mechanisms to continuously monitor cloud security posture and risk exposure across the organization
Provide executive visibility into cloud security risks, trends, compliance posture, and program effectiveness
Partner with compliance, privacy, risk management, and security operations teams to address regulatory requirements and emerging threats
Develop metrics and KPIs to measure cloud security maturity, remediation effectiveness, and operational performance
Partner with the Cloud Center of Excellence (Cloud CoE) and development teams to integrate security capabilities into cloud platforms and engineering workflows
Establish clear accountability models where development teams own remediation and risk reduction activities within their services
Ensure security findings are identified, prioritized, and routed to the appropriate service owners through automated processes whenever feasible
Enable development teams to manage security risks independently by providing guidance, training, tooling, and consulting support
Act as a trusted security advisor for cloud-related initiatives across multiple business units
Drive a culture in which security is embedded into engineering processes without reducing development velocity
