You're experienced with modern inference systems like TGI, vLLM, TensorRT-LLM, and Optimum, and comfortable creating custom tooling for testing and optimization. * **Approach:** You combine technical expertise with practical problem-solving. You're methodical in debugging complex systems and can rapidly prototype and validate solutions. ### **The core work will include:** * Architecting and implementing robust, scalable inference systems for serving state-of-the-art AI models * Optimizing model serving infrastructure for high throughput and low latency at scale * Developing and integrating advanced inference optimization techniques * Working closely with our research team to bring cutting-edge capabilities into production * Building developer tools and infrastructure to support rapid experimentation and deployment. ### **Bonus points if you:** * Have experience with low-level systems programming (CUDA, Triton) and compiler optimization * Are passionate about open-source contributions and staying current with ML infrastructure developments * Bring practical experience with high-performance computing and distributed systems * Have worked in early-stage environments where you helped shape technical direction * Are energized by solving complex technical challenges in a collaborative environment This is an in person role at our office in SF.
