募集要項

About the Role

You will join an existing SRE / DevOps team that has significant autonomy in deciding how to manage and improve its systems. You will work on infrastructure, observability, automation, and developer enablement, collaborating with engineers across the organization. Communication takes place in both English and Japanese, with tools used where possible to make collaboration more efficient.

The role draws on principles similar to those described in Google’s Site Reliability Engineering practices, with an emphasis on reliable production systems, automation, and continuous improvement.

Key Responsibilities

• Design, maintain, and improve cloud infrastructure, particularly on AWS.
• Build and maintain Infrastructure-as-Code solutions, primarily using Pulumi and TypeScript.
• Operate and improve observability, monitoring, alerting, and incident investigation workflows using Datadog.
• Support container-based environments and delivery pipelines, including ECS / Kubernetes and CI/CD.
• Automate operational tasks and help product engineering teams use infrastructure safely and effectively.
• Improve system reliability, availability, performance, and operational efficiency.
• Participate in the on-call rotation, approximately one week in every six weeks.

Technology Stack

The stack includes (but is not limited to):

• TypeScript and Node.js
• AWS: ECS, CloudFront, S3, SQS, and Lambda
• Pulumi for Infrastructure as Code
• Datadog for observability and monitoring
• Container-based environments, including ECS and Kubernetes
• CI/CD tooling, including GitHub Actions and Argo CD
• Vercel
• React
• MongoDB and Redis
