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
Translate core mathematical operations from transformer models into optimized operation sequences for Sohu
Develop and leverage a deep understanding of Sohu to co-design both HW instructions and model architecture operations to maximize model performance
Implement high-performance software components for the Model Toolkit
Collaborate with hardware engineers to maximize chip utilization and minimize latency
Implement efficient batching strategies and execution plans for inference workloads
Design and implement cutting edge inference time compute scaling methods
Alter and fine-tune model architectures or inference time compute algorithms
Contribute to the evolution of our system architecture and programming model
Representative projects
Optimize operation sequences to maximize Sohu's computational resources for specific transformer architectures such as Llama 4.
Research and implement efficient memory management for KV cache sharing and prefix optimization
Develop algorithms for continuous batching and batch interleaving to improve throughput and/or latency
Research and implement model-specific inference-time acceleration algorithms such as speculative decoding, tree search, KV cache sharing, priority scheduling, etc by interacting with the rest of the inference serving stack
Research and implement structured decoding and novel sampling algorithms for reasoning models

How we’re different
Etched believes in the Bitter Lesson. We think most of the progress in the AI field has come from using more FLOPs to train and run models, and the best way to get more FLOPs is to build model-specific hardware. Larger and larger training runs encourage companies to consolidate around fewer model architectures, which creates a market for single-model ASICs.
We are a fully in-person team in West San Jose, and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
