The Technology Platforms Division (TPD) drives the growth of Rakuten's ecosystem by delivering innovative, high-quality technology platforms characterized by integrated control and strategic partnerships.
Within TPD, the Cloud Platform Supervisory Department (CPSD) develops and manages Rakuten's state-of-the-art cloud platform, empowering global scalability and accelerating innovation across its diverse business units.
The Cloud Platform Enablement Department (CPED) drives Rakuten Group's global infrastructure strategy by building and operating a robust private cloud platform and supporting public cloud environments. We empower application engineers to build reliable and scalable systems while ensuring unified support and consistent quality across all departments.
The Cloud Centre of Excellence (CCoE) is a cross-functional team responsible for creating and implementing cloud-related best practices, guidelines, and governance policies. Our primary mission is to ensure that cloud resources are used effectively and efficiently to achieve Rakuten's business objectives. We drive our multi-cloud strategy across GCP, AWS, Azure, and OCI, accelerating cloud adoption, enhancing security, standardizing processes, fostering faster innovation, and optimizing cost efficiency (FinOps) throughout the organization.
As public cloud adoption continues to grow across the organization, we need dedicated cloud engineers to handle the increasing volume of cloud requests, configuration tasks, and user inquiries. We are looking for an engineer who can take ownership of day-to-day cloud operations and grow as a core member of the team, enabling existing members to focus on higher-level architecture and governance work.
You will be responsible for day-to-day cloud operations across our multi-cloud environment (AWS, Azure, GCP, OCI), while also collaborating with internal teams and vendors, driving improvements to existing cloud environments, and contributing to team knowledge management.
