• Build and maintain infrastructure automation using technologies such as Terraform, Helm, and Kustomize.
• Operate and improve production Kubernetes and container orchestration environments.
• Manage container registries and artifact platforms such as Artifactory, Harbor, or equivalent technologies.
• Develop automation and developer self-service capabilities to simplify onboarding and reduce repetitive operational tasks.
• Establish and improve monitoring, alerting, logging, and capacity management processes.
• Maintain platform availability and reliability through proactive monitoring and incident management.
• Manage platform upgrades, plugins, configurations, security patches, and other technology-stack updates.
• Partner with internal development teams to understand engineering requirements and improve platform services and developer experience.
• Participate in operational support rotations and investigate production or platform incidents.
• Conduct post-incident reviews and contribute to preventative improvements.
• Promote DevOps and Site Reliability Engineering (SRE) best practices across the engineering organisation.

• Experience with Infrastructure as Code technologies such as Terraform, Helm, or Kustomize.
• Strong scripting and automation experience using Python, Bash, Groovy, or comparable languages.
• Experience with monitoring, logging, and alerting technologies such as Prometheus, Grafana, or ELK.
• Experience supporting production infrastructure, platform services, or developer tooling.
• Understanding of incident management, troubleshooting, and platform reliability practices.

Soft Skills:

• Strong collaboration skills for working with software developers, infrastructure engineers, and other technical stakeholders.
• Proactive approach to identifying platform issues and implementing scalable improvements.
• Strong troubleshooting and problem-solving skills for complex infrastructure and CI/CD environments.
• Ability to balance platform reliability, security, scalability, and developer experience.
• Strong ownership mindset with the ability to manage operational responsibilities effectively.
• Interest in automation and eliminating repetitive manual processes.
• Ability to work effectively within an international and geographically distributed engineering organisation.

Language Requirements:

• Japanese: Basic-level proficiency is sufficient for this position.
• English: Fluent-level proficiency required for daily collaboration within an international engineering and Platform Engineering environment.

Preferred Skills & Qualifications
