Senior DevOps/Site Reliability Engineer

About the role

This Senior DevOps/Site Reliability Engineer will be responsible for enhancing the performance and scalability of Limit Break's multi-cluster EKS environment on AWS. The role involves identifying and executing improvements, measuring system health, and troubleshooting production issues. A key aspect is using code to address operational challenges within the company's infrastructure and platform.

The position requires close collaboration with the broader engineering team to ensure testing environments accurately reflect production. A core responsibility is to define and improve SLOs, SLIs, monitoring, alerting, and incident response practices. The engineer will also continuously refine the observability stack, which includes tools like Grafana, Thanos, and Loki, to support global scalability.

Success in this role means proactively addressing system bottlenecks, ensuring robust and scalable infrastructure, and maintaining high operational standards. The engineer will contribute to a secure and efficient environment, working with various tools for monitoring, automation, and security to protect the system in real-time and remediate vulnerabilities.

The salary for this position ranges from $160,000 to $218,000 USD annually.

Skills that matter here

• Kubernetes: The role requires operating and optimizing multiple EKS clusters in a production environment.
• AWS: Extensive experience with AWS services, including Aurora, RDS, and networking, is essential for managing the cloud infrastructure.
• Terraform: This tool is used for infrastructure as code, requiring strong experience in its application.
• Ansible: The role involves using Ansible for automation and configuration management.
• CI/CD: Experience with continuous integration and continuous delivery pipelines is necessary for deploying services and automating workflows.
• Grafana: This tool is part of the observability stack that the engineer will continuously improve for monitoring and alerting.

Who this role suits
