We already power Rakuten Mobile’s pre-sale onboarding and support (“RMAA”) and are building the pipeline for customer service and engagement experience.

As the CXD expands its AI-powered products and services across Rakuten Group, we need a skilled DevOps professional to build and operate the reliable, scalable, and secure infrastructure behind them.

In this role, you will enable engineering and data teams to deliver AI solutions faster and more confidently by improving deployment automation, cloud operations, system observability, and platform reliability. Your work will directly support customer-facing services used across Rakuten’s global ecosystem.

Position Details

A full-time, mid-level (2-3 years) role requiring a Bachelor's degree in Computer Science, Engineering, or a related field, working alongside senior engineers in a contributor capacity rather than a lead position.

The role includes participation in a 24/7 on-call rotation (incident response, postmortems, runbook upkeep), applying security and compliance practices to infrastructure and pipelines, and exposure to AIOps tooling and AI-driven operational insights - all while collaborating closely with software development teams and cross-functional/international stakeholders, for which mandatory written and verbal English proficiency is required.

・Bachelor's degree in Computer Science, Engineering, or a related field

・Minimum 2 years of experience in DevOps or related roles, with exposure to cloud infrastructure and Kubernetes

・Working knowledge of at least one major cloud platform (AWS, GCP, or Azure)

・Understanding of CI/CD principles with experience using Jenkins, GitLab CI, or similar

・Hands-on experience with infrastructure as code (Terraform, Ansible, or similar)

・Strong problem-solving skills and ability to troubleshoot in a distributed environment

・Good communication skills, able to work with cross-functional teams

・English proficiency (written and verbal) - explicitly stated as mandatory

・Japanese Proficiency -  JLPT N2 or higher

Desired Qualifications:

・Familiarity with monitoring/logging tools such as Prometheus, Grafana, or the ELK Stack (phrased as "familiarity," softer than the hands-on requirements above)

・Comfort with Python for scripting and basic data manipulation (phrased as "comfort with," not "hands-on experience")
