Responsibilities

• Design and train NLP models for tasks like classification, entity extraction, retrieval, summarization, and semantic search

• Hands-on experience fine-tuning transformer models (LoRA/QLoRA, instruction tuning, preference optimization) and/or building production RAG systems
• Solid grounding in evaluation: knows the difference between BLEU/ROUGE/BERTScore/LLM-as-judge and when each is misleading
• Comfortable with SQL, vector databases (pgvector, Pinecone, Weaviate, or similar), and one major cloud (AWS/GCP/Azure)
• Clear written and verbal communication; can defend a modeling choice and also admit when a heuristic beats a model
• Publications at ACL/EMNLP/NAACL/NeurIPS or strong open-source contributions
