Qualifications

• Extensive experience designing, operating, and troubleshooting production infrastructure in AWS.

• Build secure, scalable infrastructure across AWS and other cloud environments using infrastructure as code and repeatable automation.
• Improve production reliability through well-defined SLOs, graceful degradation, self-healing, automated recovery, and effective incident response.
• Create self-service workflows and platform abstractions that reduce cognitive load and help R&D teams ship and operate software more effectively.
• Partner with Information Security, Cost Optimization, and engineering teams to strengthen controls, improve cloud efficiency, influence technical direction, and contribute to the platform roadmap.
