Deploy and operate large-scale Elasticsearch clusters supporting log analytics, search, and operational troubleshooting.

Design, deploy, and support distributed tracing platforms using Grafana Tempo and Open Telemetry.

Build and maintain end-to-end telemetry pipelines for logs, metrics, and traces.

Define instrumentation standards, data quality practices, retention policies, and observability patterns.

Scale and optimize Prometheus, Grafana, Kafka, Tempo, Open Telemetry, and related monitoring systems.

Develop dashboards, alerts, analytics, and trace visualizations using Splunk SPL, Grafana, Kibana, and Tempo.

Establish monitoring and alerting standards that improve service-level visibility and reduce mean time to detect and resolve incidents.

Automate infrastructure provisioning, configuration, upgrades, and operational processes using Terraform and configuration management tools.

Participate in capacity planning, performance tuning, upgrades, patching, disaster recovery, and production readiness reviews.

Troubleshoot complex distributed-systems issues and lead or support incident response and root-cause analysis.

Partner with platform, application, security, database, and network engineering teams to improve reliability and operational consistency.

Contribute to shared SRE standards, documentation, runbooks, and engineering best practices.
