- Ability to work effectively across research, systems, infrastructure, and product teams.

- Excellent communication and problem-solving skills, with the ability to thrive in a fast-paced and collaborative environment.

## Preferred Qualifications

- Experience with weight-only, activation, KV-cache, dynamic, static, or mixed-precision quantization.

- Experience with AWQ, GPTQ, SmoothQuant, or related methods.

- Strong numerical analysis and systems engineering skills.

- Experience with one or more LLM runtimes, such as TensorRT-LLM, vLLM, SGLang, llama.cpp, ONNX Runtime, TVM, MLIR, or custom runtimes.

- Experience deploying LLMs on resource-constrained or heterogeneous hardware.

- Contributions to model optimization, inference, compiler, or serving projects.

- Publications at NeurIPS, ICML, ICLR, ACL, or related conferences.

## What We Provide

- A fun, supportive and engaging environment.
