Staff Software Engineer, Observability & Profiling

Overview

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.

Pay / Benefits

• competitive compensation
• visa sponsorship available
• office space in San Francisco
• generous vacation and parental leave
• flexible working hours
• equity donation matching (optional)

Responsibilities

• Design and build scalable telemetry ingest and storage pipelines for metrics, logs, traces, and error data across Anthropic's multi-cluster infrastructure
• Develop observability solutions that provide low-overhead visibility into system behavior across the fleet
• Own and evolve core observability platforms, driving migrations and architectural improvements for reliability and cost efficiency
• Create instrumentation libraries, SDKs, and eBPF-based auto-instrumentation to emit high-quality telemetry
• Reduce MTTR through cross-signal correlation, unified query interfaces, and AI-assisted diagnostic tooling
• Drive fleet-wide efficiency via continuous profiling and utilization telemetry to guide optimizations across CPUs, memory, and accelerators
• Collaborate with Research, Inference, Product, and Infrastructure teams to tailor observability solutions to diverse needs

Key requirements

• Hands-on experience building and operating large-scale observability or monitoring infrastructure
• Deep hands-on experience with observability signals from instrumentation through ingest to query and analysis
• Understanding of high-throughput telemetry pipelines and scale tradeoffs for data collection, storage, and querying
• Comfort digging below the application layer into kernel, network stack, or hardware
• Excellent communication skills and ability to partner with internal teams on visibility and incident response
• Interest in building foundational infrastructure and navigating ambiguous, high-impact technical challenges

• Strong collaboration skills
• Problem-solving orientation
• Proactive communication
• eBPF-based observability in production
• OpenTelemetry instrumentation, collector pipelines, and tail-based sampling
• Continuous profiling at fleet scale and symbolization
