About this role

Performance Modeling Engineer San Jose, CA, United States About Etched Etched is building the world's first AI inference system purpose-built for transformers - delivering over 10x higher performance and dramatically lower cost and latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history. Key responsibilities - Develop comprehensive performance models and projections for Sohu's transformer-specific architecture across varying workloads and configurations - Profile and analyze deep learning workloads on Sohu to identify micro-architectural bottlenecks and influence optimization opportunities - Drive hardware/software co-optimization by identifying where architectural features can unlock performance improvements - Run regressions and validate performance models against real systems and silicon - Inform next-generation architectural decisions by pathfinding across system and silicon options during design, proof-of-concept, and architecting phases You may be a good fit if you have at least one of the following: - Strong performance modeling and analysis skills with experience building analytical-based or simulation-based performance models - Solid understanding of computer architecture and micro-architecture, particularly for accelerators - Experience profiling and analyzing deep learning workloads on hardware accelerators (GPUs, TPUs, ASICs, FPGAs, or others) - Solid software engineering fundamentals with an eye toward auditability and maintainability Strong candidates may also have - Deep knowledge of GPU architectures and/or programming
