• Identify manual tasks and lead the development of automation to eliminate them.
• Develop and maintain automated runbooks and playbooks for operational tasks and incident response.
• Enhance system observability using high-cardinality data for proactive insights.
• Proactively identify and mitigate operational risks through chaos engineering and architecture reviews.
• Collaborate with software engineers to ensure reliability, scalability, and maintainability from the early stages of the SDLC.
• Continuously evaluate and optimize system performance, capacity, and cost efficiency.
• Refine the on-call experience to reduce alert fatigue, improve MTTR, and ensure sustainable rotation health.
