• 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 OpenTelemetry.
• 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, OpenTelemetry, 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.
• Participate in the shared SRE pager and on-call rotation for production services.

• 7+ years of related experience, or Master + 4 years of related experience, or PhD + 1 year of related experience in Site Reliability Engineering, Platform Engineering, DevOps, or a related field.
• Experience administering Splunk Enterprise or Splunk Cloud in a production environment, with solid understanding of Splunk SPL for dashboards and alerts.
• Experience designing, deploying, and operating Elasticsearch or ELK-based platforms, along with Prometheus, Grafana, distributed tracing (Grafana Tempo, OpenTelemetry), and Kafka.
• Experience in Infrastructure as Code using Terraform and understanding of Linux, networking, distributed systems, and production operations.
• Programming or scripting experience in Python, Go, Ruby, Bash, or similar languages, with demonstrated ability to troubleshoot production incidents and participate in on-call support.

• Experience with Kubernetes and containerized production workloads.
• Experience operating cloud infrastructure in AWS, Azure, or GCP.
• Experience with Ansible, Consul, CI/CD pipelines, or service mesh technologies.
• Experience with reliability engineering practices, including SLOs, SLIs, error budgets, capacity planning, and incident management.
• Demonstrated experience implementing and operating modern observability strategies across logs, metrics, and traces
• Experience supporting FedRAMP, government, or other regulated environments.
