About the role

Software Engineer role on Anthropic's Observability team within the Infrastructure organization to design, build, and evolve scalable telemetry and profiling systems across multi-cluster GPU/TPU/Trainium infrastructure, enabling rapid detection, diagnosis, and resolution of issues with AI systems.

Responsibilities

  • Design and build scalable telemetry ingest and storage pipelines for metrics, logs, traces, and error data across Anthropic's multi-cluster infrastructure
  • Build observability solutions that give engineers deep, low-overhead visibility into system behavior across the fleet
  • Own and evolve core observability platforms, driving migrations and architectural improvements that improve reliability, reduce cost, and scale with organizational growth
  • Build instrumentation libraries, SDKs, and eBPF-based auto-instrumentation to emit high-quality telemetry, with and without code changes
  • Reduce mean time to detection and resolution by building cross-signal correlation—from kernel-level events up to application traces—unified query interfaces, and AI-assisted diagnostic tooling
  • Drive fleet-wide efficiency by turning continuous profiling and utilization telemetry into actionable optimization insights across CPU, memory, and accelerator fleets
  • Partner with Research, Inference, Product, and Infrastructure teams to ensure observability solutions meet the unique needs of each organization

Qualifications

  • Have hands-on experience building and operating large-scale observability or monitoring infrastructure
  • Have deep, hands-on experience with observability signals end to end—from instrumentation through ingest to query and analysis
  • Understand high-throughput telemetry pipelines and the tradeoffs involved in collecting, storing, and querying operational data at scale
  • Are comfortable digging below the application layer into the kernel, the network stack, or the hardware
  • Have excellent communication skills and enjoy partnering with internal teams to improve their operational visibility and incident response capabilities
  • Are excited about building foundational infrastructure and comfortable navigating ambiguous, high-impact technical challenges, both independently and with a team
