Head of Performance Visibility

Key Responsibilities

• Mentorship And Leadership System-Level Performance Design
• Define the architectural approach for collecting and structuring telemetry across CPUs, drivers, interconnects, and multiple accelerators
• Design scalable models for correlating performance events across device and host boundaries
• Cross-Layer Event Correlation
• Develop mechanisms to align hardware counters, runtime activity, communication phases, and workload semantics across model-layer execution into coherent, actionable insight
• Implement time synchronization and trace-alignment strategies across multi-device systems
• Telemetry & Counter Modeling
• Define structured counter taxonomies separating base signals from derived metrics
• Design derived performance models bridging low-level hardware signals and workload-level behavior
• Influence instrumentation strategy for future hardware generations
• Distributed Performance Reasoning
• Build tools that identify bottlenecks among multi-accelerator workloads across chips within hosts
• Build cluster-scale performance analysis for distributed inference across data center networks
• Tooling & Insight Delivery
• Contribute to analysis engines and developer-facing tooling that transform raw telemetry into intuitive insight
• Shape how performance intelligence is surfaced to engineers debugging large-scale AI systems
