About the Role

This internship program focuses on advancing search quality through deep learning models, research, and RAG pipeline development.

Responsibilities

  • Advance search quality through models, data, tools, or other available leverage.
  • Train and optimize large-scale deep learning models using PyTorch, distributed training, and hardware acceleration, focusing on retrieval and ranking models.
  • Conduct research in representation learning, including contrastive learning, multilingual, evaluation, and multimodal modeling for search and retrieval.
  • Build and optimize RAG pipelines for grounding and answer generation.

Requirements

  • Understanding of search and retrieval systems, including quality evaluation principles and metrics.
  • Strong proficiency with PyTorch, including experience in distributed training techniques and performance optimization for large models.
