Clarivate is hiring a Senior Data Scientist (NLP)

Clarivate is hiring a Senior Data Scientist (NLP) to design and implement large-scale AI-enabled solutions that modernize our content delivery systems. You will specialize in Natural Language Processing (NLP) and modern retrieval-augmented generation (RAG) architectures, focusing on text processing pipelines, indexing, vectorization, prompting, fine-tuning, and context management.

What You'll Do

• Design scalable NLP workflows for text ingestion, cleaning, normalization, and tokenization.
• Implement and maintain robust indexing systems and vector databases for semantic search and retrieval.
• Develop reusable prompting strategies and lead fine-tuning initiatives for LLMs tailored to business tasks.
• Build dynamic knowledge systems and agentic workflows using LangChain and LangGraph.
• Integrate advanced RAG architectures like VRAG and GraphRAG to enrich information retrieval.
• Conduct benchmark testing and model evaluations to improve accuracy, efficiency, and scalability of NLP systems.
• Collaborate with engineering, product, and research stakeholders to deliver integrated AI-driven features.
• Mentor junior data scientists, guide best practices, and drive innovation across AI projects.

What We're Looking For

• Bachelor’s degree in Computer Science, Data Science, Computational Linguistics, or a related field.
• At least 5 years of hands-on experience in data science, focused on natural language processing (NLP).
• At least 5 years of experience using Python, with expertise in NLP libraries such as LangChain, LangGraph, or other “Lang”-based toolkits.
• Proven experience in model development and applying machine learning techniques to real-world problems.

Nice to Have

• Expertise in retrieval-based LLM workflows (RAG, VRAG, GraphRAG).
• Deep understanding of embedding models, semantic search, and vector stores (e.g., FAISS, Pinecone).
• Experience with document loaders and text splitters/document splitting strategies.
• Familiarity with MLOps practices and production-level deployment of AI pipelines.
• Experience with cloud platforms (e.g., AWS, Azure, or GCP).
• Experience applying Graph Neural Networks (GNNs) to retrieval-enhanced generation.
• Knowledge of LangSmith and vector orchestration platforms.
• Familiarity with multilingual NLP and cross-lingual embeddings.
• Exposure to real-time knowledge graphs and stream-based RAG systems.
• A Master’s or PhD in a technical field (Computer Science, Data Science, etc.).
