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.
Job Responsibility:
Support porting state-of-the-art models to our architecture
Help build programming abstractions and testing capabilities to rapidly iterate on model porting
Build, enhance, and scale Sohu’s runtime, including multi-node inference, intra-node execution, state management, and robust error handling
Optimize routing and communication layers using Sohu’s collectives
Utilize performance profiling and debugging tools to identify bottlenecks and correctness issues
