• Build high-performance telemetry pipelines that handle massive ingestion volumes.
• Develop APIs, query engines, and UIs that allow engineers to get real-time insights into their services.
• Define and enforce best practices for instrumentation, alerting, and reliability across the company.
• Partner with infrastructure and product teams to deeply integrate observability into our internal platforms.
• Own the reliability, scalability, and performance of the observability stack end-to-end.
