Role - Senior / Lead Data Scientist – Generative AI (RAG & Multi-Agent Systems)

Experience

6+ years (Senior / Lead Data Scientist)

We are looking for a Senior Developer/Lead Data Scientist to build and scale an enterprise-grade GenAI chatbot platform that integrates with multiple RAG (Retrieval Augmented Generation) systems to deliver accurate, grounded, and secure responses at high concurrency. You will own architecture and hands-on development across LLM orchestration, retrieval pipelines, evaluation, and production deployment

Key Responsibilities

• Design and build a scalable GenAI chatbot that orchestrates and calls multiple RAG systems (routing, retrieval, re-ranking, response generation).
• Implement multi-agent architectures (where required) using frameworks like LangChain, AutoGen, or similar.
• Develop robust Python services/APIs (FastAPI preferred) with streaming responses, retries, rate limits, and observability.
• Build and optimize RAG pipelines: data ingestion, chunking strategies, embeddings, vector indexing, hybrid retrieval, metadata filtering, and context management
• Evaluate and improve response quality using offline/online evaluation, feedback loops, and guardrails to reduce hallucinations.
• Integrate Azure OpenAI / OpenAI GPT models and manage prompt/versioning strategies for different use-cases.
• Ensure production readiness: performance optimization, cost control, caching, monitoring, alerting, CI/CD, and secure deployments.
• Collaborate with product and engineering teams to define requirements, SLAs, and rollout plans.

Must Have Skills

• Strong proficiency in Python and AI/ML libraries: PyTorch / TensorFlow, Scikit-learn
• Hands-on experience with Generative AI and LLMs (e.g., Azure OpenAI GPT) in production.
• Strong understanding of Data Science fundamentals preprocessing, feature engineering, model evaluation, metrics.
• Experience building RAG systems embeddings, vector search, retrieval strategies, re-ranking, and grounding.
• Experience with LangChain, AutoGen, or similar orchestration frameworks.
• Solid software engineering practices: clean architecture, testing, code review, documentation.

Nice to Have

• Familiarity with Big Data tools: Spark, Hadoop, Databricks
• Experience with databases: SQL / NoSQL, and vector databases/search (Azure AI Search, Pinecone, Weaviate, Qdrant, etc.).
• Experience with ReactJS for building responsive chat UIs with streaming.
• Knowledge of MLOps tooling and cloud deployment patterns (Docker/Kubernetes).

What You’ll Build / Deliverables

• Multi-RAG chatbot orchestration layer (routing + tool calling).
• Scalable retrieval and generation services with caching and observability.
• Evaluation harness (quality + hallucination checks) and feedback-driven improvements.
• Secure, multi-tenant ready system (if applicable) with access control.

Education

• B.Tech/M.Tech in CS/IT/Data Science (or equivalent practical experience).
