• Analyze metrics, logs, and distributed traces across application and infrastructure layers to proactively identify issues and support effective root cause analysis (RCA)
• Own and execute blameless RCAs for production incidents, identify corrective and preventive actions, and track them to closure
• Implement minor code fixes, configuration updates, and reliability enhancements as part of incident remediation and preventive measures
• Collaborate with application development and platform teams to review defects, propose fixes, and improve overall service reliability
• Participate in Agile sprint planning ceremonies, backlog grooming, estimation, and delivery of SRE‑owned work items
• Drive reliability improvements through sprint‑based commitments, including automation, operational fixes, and platform enhancements
• Participate in Disaster Recovery (DR) planning, testing, and execution to ensure resilience of business‑critical services
• Perform regular system patching and maintenance activities in line with organizational security, compliance, and audit requirements
• Support ITIL‑based Incident, Problem, and Change Management processes, including planning, documentation, approvals, execution, and post‑implementation validation
• Monitor network performance and troubleshoot connectivity, latency, and access‑related issues impacting platform traffic
• Participate in certificate lifecycle management, including provisioning, renewal, validation, and troubleshooting of SSL/TLS certificates
• Maintain and manage service accounts (Service IDs), including access provisioning, credential rotation, and compliance with security policies
• Drive automation and operational toil reduction using scripting, CI/CD pipelines, and platform tooling to improve reliability and scalability
• Maintain accurate documentation of system configurations, runbooks, SOPs, platform operational guidelines, and troubleshooting procedures, and generate reports on system performance, incidents, and resolutions

Education and Knowledge
