• Design and implement scalable operations tooling to support platform growth and scaling across multiple regions.
• Design, deploy, and maintain AWS cloud-native services that are elastic and resilient to failure.
• Participate in and improve our 24x7 incident response and on-call rotation.
• Use and expand our existing CNCF solutions like Kubernetes, Service Mesh, Prometheus, OpenTelemetry, and ArgoCD to increase platform reliability.
• Automate production operations to provide guardrails and continuous platform operation.
• Develop automation solutions for scalable service and platform operations, including deployment, scale testing, graceful failure, and chaos testing.
• Stay updated on industry best practices for scalability and reliability to improve the scalability of the ThousandEyes platform.
• Identify and provide solutions to common obstacles hindering operational excellence across engineering teams.
• Generalize and standardize solutions and processes to enable repeated success across our microservice-based multi-region platform.
• Play a key role in the ThousandEyes platform by leveraging scale testing, additional environments, and working with application teams to improve system reliability.
• Manage a rapidly growing infrastructure capable of handling substantial daily data volumes, emphasizing operations/infrastructure/everything as code.

Qualifications

• Expert-level knowledge of Kubernetes and its ecosystem.
• Proficiency in software development with languages such as Python or Go.
• In-depth knowledge of cloud providers, preferably AWS.
• Proven ability to build and implement scalable and well-tested solutions.
• Strong understanding of Unix/Linux systems, including kernel, system libraries, file systems, and client-server protocols.
• Knowledge of Site Reliability principles: Incident Response, Change Management, Distributed Systems, Deployment Strategies, and SLOs.

Preferred Qualifications

• Familiarity with best practices for operating a large-scale, highly available enterprise platform.
• 5+ years of experience in a related role.
• Excellent communication and documentation skills.
• Strong sense of ownership, drive, and attention to detail.
