Site Reliability Engineer — ML Infrastructure

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. We emphasize DevOps best practices such as agile, scrum, automation, and customer-centric improvements.

TableCheck has embraced remote work. As such, communication and documentation are in our blood. We look for and write about signals in the noise which enables us to constantly learn from mistakes and adapt, and we expect members of our teams to constantly follow up with questions and updates to keep everyone in the loop.

• Building and maintaining CI/CD pipelines, infrastructure as code (Terraform, Helm, ArgoCD)

• Ensuring system reliability, performance, and scalability across our production stack

Machine Learning

• Applying SRE discipline to ML infrastructure — ensuring model serving, training pipelines, and data systems are reliable, observable, and well-operated

• Supporting and improving ML model deployment pipelines and MLOps practices

• Monitoring ML model performance in production and building alerting and observability for ML systems

• Collaborating with data scientists and product teams to operationalize ML models at scale

• Experience running production systems at large scale, and an understanding of the kinds of problems that can occur along with likely solutions

• Familiarity with machine learning workflows and MLOps practices

• Python experience with ML-adjacent tooling (model deployment, inference serving, or ML pipeline tooling)

Recommended Skills

• Previous startup experience is highly desired

• Terraform, Pulumi

• ArgoCD

• Prometheus and Grafana for monitoring and alerting

• PostgreSQL and MongoDB

• Kafka for event-driven architecture

• Security, PCI-DSS, GDPR, forensics

• Experience with ML model serving frameworks (e.g., TensorFlow Serving, TorchServe, Triton)

• Familiarity with feature stores, experiment tracking, or model registry tools

• Experience deploying and managing ML workloads on Kubernetes
