Cloud Architect - CCoE Section, Cloud Platform Enablement Department (CPED)

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.

Provide upper-level architecture reviews for service teams across multi-cloud environments

Define reference architectures for Landing Zones, account structures, and network design (VPCs, VPNs, Dedicated Interconnect, Cloud to Cloud Connectivity, hub-and-spoke, etc.)

Conduct architecture reviews based on the Well-Architected Framework for AWS, Azure, GCP, and OCI

Provide technical consulting on cloud migration and modernization plans for each Business Unit (BU)

Design, implement, and continuously improve the multi-cloud governance framework

Architect security guardrails and compliance policies (IAM, network controls, encryption, audit logging, etc.)

Support the cloud-side implementation of Zero Trust Architecture and CSPM in collaboration with the dedicated security team

Collaborate with security and legal teams on risk assessment and remediation design

Provide technical leadership for CCoE roadmap initiatives (Security Guardrails, Landing Zone, etc.)

Drive codification and standardization of infrastructure architecture using IaC tools such as Terraform

Provide architecture guidance on container platforms (Kubernetes), serverless, and managed service adoption

Standardize Disaster Recovery (DR), High Availability (HA), and scalability design

Define FinOps strategy and design 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

Drive architectural improvements to reduce data egress costs

Provide technical mentoring and architecture reviews for Cloud CoE engineers

Operate an Architecture Review Board for internal cloud users

Create and promote cloud architecture best practices and design guidelines across the organization

Research and evaluate new technologies and services, and assess their integration into existing architecture

Develop and create e-Learning content

Serve as the primary technical point of contact for cloud vendors (AWS, GCP, Azure, OCI) and build strong vendor relationships

Evaluate new vendor services and roadmaps and determine their applicability for internal adoption

Collaborate with Co-CCoE organizations (equivalent CCoE teams in other groups/departments) to align architecture standards

Work with external partners on cross-group cloud strategy and governance initiatives
