Inference Software Engineer
Etched · San Jose
About this role
## About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference—backed by hundreds of millions from top-tier investors and staffed by leading engineers. ## 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. - Build, enhance, and scale our runtime, including multi-node inference, intra-node execution, state management, and robust error handling. - Optimize routing and communication layers using our collectives. - Use performance profiling and debugging tools to identify bottlenecks and correctness issues. ## You may be a good fit if you have - Proficiency in **C++ or Rust**. - Understanding of performance-sensitive or complex distributed software systems (e.g., Linux internals), accelerator architectures (e.g., GPUs/TPUs), compilers, or high-speed interconnects (e.g., NVLink, InfiniBand). - Familiarity with **PyTorch or JAX**. - Ported applications to non-standard accelerator hardware or hardware platforms. ## Strong candidates may also have (Nice-to-have) - Developed low-latency, high-performance applications using both kernel-level and user-space networking stacks. - Deep understanding of distributed systems concepts, algorithms, and challenges (e.g., consensus protocols, consistency models, communication patterns). - Solid grasp of Transformer architectures, particularly **Mixture-of-Experts (MoE)**. - Built performance-critical applications with extensive **SIMD** optimizations. ## Benefits - Medical, dental, and vision packages with generous premium coverage - **$500/month** credit for waiving medical benefits - **$2.5k/month** housing subsidy for those living within walking distance of the office - Relocation support for those moving to **San Jose (Santana Row)** - Wellness benefits covering fitness, mental health, and more - Daily lunch + dinner in our office - Unlimited compute budget subject to ROI justification ## How we’re different Etched believes in the *Bitter Lesson* (http://www.incompleteideas.net/IncIdeas/BitterLesson.html). We’re the first inference-focused frontier AI system, with an addressable market spanning the entirety of inference. We’re a fully in-person team in San Jose (Santana Row). We value engineering skills and do not separate engineering from research—expecting technical staff to contribute to both and work across disciplines as needed.
