Welcome to visit our website at AI Research Areas | Intelligence on Devices | Qualcomm.

Key Responsibilities

• Lead or contribute to the end-to-end training, fine-tuning, and quantization of LLM/LVM/LMM models, especially in low-bit quantization

• Design and implement scalable, robust systems and engineering pipelines for model training, evaluation, quantization (PTQ and QAT), and can support customers' on-device deployment.

• Algorithms research and development in VLM, VLA and other multimodality models, diffusion-based methods for image and text generation, efficient computation (MoE, LoRA or others).

• Experience of multimodal inference and training, such as image generation, 3D, video generation, editing, ViT and other models.

• Efficient inference algorithms research and advanced quantization, e.g. batching, KV caching, efficient attentions, long context, speculative decoding, GPTQ, Spin Quant, automatic mixed precision.

• Apply solutions toward systems innovations for model efficiency advancement on device as well as in the cloud.

• Research and integrate state-of-the-art algorithms in generative AI, quantization techniques, knowledge distillation, model compression, and efficient inference.

• Build, maintain, and automate test suites and profiling/debugging tools to validate and benchmark model performance and deployment effectiveness.

• Document methodologies and results, and present key findings to stakeholders.

Preferred Skills and Experience:

• Solid programming skills in Python, with proficiency in Py Torch;

• Demonstrated experience in both PTQ (Post-Training Quantization) and QAT (Quantization-Aware Training) for deep neural networks, especially under low-bit (≤8 bits) regimes.

• Hands-on experience with training or quantization pipelines such as Llama Factory or AIMET.

• Experience in LoRA adapter-tuning, speculative decoding, model compression.

• Experience in developing or optimizing memory-efficient, high-speed inference engines such as vLLM and SGLANG.

• Knowledge in start-of-the-art PTQ and QAT algorithms

• Knowledge in reinforcement learning (RL)

• Knowledge in on-device learning, federated learning, or continual learning

• Experience using AI coding assistants such as Claude code, Codex, or Cursor is a plus
