Staff Software Engineer, Observability & Profiling

In this role you will design and evolve scalable observability infrastructure to give engineers deep visibility into multi-cluster systems. You’ll work with cross-functional teams to improve reliability, reduce incident response time, and scale telemetry from kernel to application level. The role focuses on building high-throughput data pipelines, instrumentation, and AI-assisted diagnostic tooling to support rapid, data-driven decisions. You’ll contribute to a mission-driven company that aims to make AI safe, steerable, and beneficial at scale.
