What are the responsibilities and job description for the Inference Software Engineer position at Etched?
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 from NVIDIA, Google, and Meta, Etched is redefining the infrastructure layer for the fastest growing industry in history.
Job Summary
Etched’s Inference SW team enables optimal mapping of models to Sohu’s dataflow architecture and serving requests across multiple chips, hosts and racks. We are seeking a highly skilled and motivated engineer to join our team as we work towards enabling Mixture-of-Experts (MoE) architectures on Sohu systems. You’ll build SW enabling frontier inference performance to satisfy exponentially growing serving demand.
This role is for a general contributor and will be expected to contribute to all parts of our stack. We also have more specialized needs for this team posted on the site.
Key Responsibilities
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.

Key Responsibilities
- Support porting state-of-the-art models to our architecture. Help build programming abstractions and testing capabilities to rapidly iterate on model porting
- Scale and enhance 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
- Develop tools for performance profiling and debugging, identifying bottlenecks and correctness issues
- Proficiency in Rust and/or C
- Good familiarity with PyTorch and/or JAX.
- Good familiarity with transformers architectures
- Ported applications to non-standard or accelerator hardware platforms.
- Solid systems knowledge, including Linux internals, accelerator architectures (e.g., GPUs, TPUs), and high-speed interconnects (e.g., NVLink, InfiniBand)
- Developed low-latency, high-performance applications using both kernel-level and user-space networking stacks.
- Deep understanding of distributed systems concepts, algorithms, and challenges, including consensus protocols, consistency models, and communication patterns.
- Solid grasp of large language model architectures, particularly Mixture-of-Experts (MoE).
- Experience analyzing performance traces and logs from distributed systems and ML workloads.
- Built applications with extensive SIMD (Single Instruction, Multiple Data) optimizations for performance-critical paths.
- Familiar with cluster orchestration tools (e.g., Kubernetes, Slurm) and ML platforms (e.g., Ray, Kubeflow)
- Experience designing and implementing CI/CD pipelines for MLOps workflows.
- Full medical, dental, and vision packages, with generous premium coverage
- Housing subsidy of $2,000/month for those living within walking distance of the office
- Daily lunch and dinner in our office
- Relocation support for those moving to West San Jose
- $175,000 - $275,000
