RakutenThe 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 expands and grows more complex across the organization, there is an urgent need to define and drive a holistic architecture strategy across our multi-cloud environment. We currently manage over 50 operations across AWS, Azure, GCP, and OCI, and require a professional who can provide enterprise-level architecture design, standardization, and technical leadership based on a deep understanding of each cloud platform. We are looking for a Cloud Architect who can lead the entire organization in designing security guardrails, standardizing network architecture, and driving the Well-Architected Framework. As a technical lead within the CCoE, you will play a broad role spanning from defining the organization-wide architecture strategy across multi-cloud environments (AWS, Azure, GCP, OCI) to establishing and driving technical standards. Responsibilities include providing upper-level architecture reviews for service teams across multi-cloud environments; defining reference architectures for Landing Zones, account structures, and network design; conducting architecture reviews based on the Well-Architected Framework for AWS, Azure, GCP, and OCI; and providing technical consulting on cloud migration and modernization plans for each Business Unit. You will design, implement, and continuously improve the multi-cloud governance framework; architect security guardrails and compliance policies; support cloud-side implementation of Zero Trust Architecture and CSPM with the dedicated security team; and collaborate with security and legal teams on risk assessment and remediation design. You will provide technical leadership for CCoE roadmap initiatives, drive codification and standardization of infrastructure architecture using IaC tools such as Terraform, provide architecture guidance on container platforms, serverless, and managed service adoption, and standardize Disaster Recovery, High Availability, and scalability design. You will define FinOps strategy and cost optimization architecture, design cost allocation, tagging standards, and cost visibility mechanisms across multiple clouds, recommend optimization of Reserved Instances, Savings Plans, and Committed Use Discounts, and drive architectural improvements to reduce data egress costs. You will mentor CCoE engineers, operate an Architecture Review Board for internal cloud users, promote cloud architecture best practices and design guidelines, research and evaluate new technologies and services, and develop e-Learning content. You will also serve as the primary technical point of contact for cloud vendors, evaluate vendor services and roadmaps, collaborate with equivalent CCoE teams across groups and departments, and work with external partners on cross-group cloud strategy and governance initiatives.
