About TableCheck

TableCheck, Japan's leading restaurant reservation management platform, is seeking a Site Reliability Engineer with machine learning expertise. As a member of our team, you will own the technology stack and help support our demanding business and developer needs. We run a robust and fault-tolerant infrastructure built on Amazon Web Services (AWS) with Terraform, Kubernetes, Helm, and an array of tools for CI/CD, logging, monitoring, and more.
