What You Will Work On

• Enterprise Generative AI and LLM applications
• Retrieval-Augmented Generation (RAG) and enterprise knowledge assistants
• AI agents and multi-step agentic workflows
• Customer churn, propensity, recommendation and segmentation models
• Intelligent document processing and information extraction
• On-premise, private-cloud and public-cloud AI architectures

Responsibilities

• Translate business objectives and data constraints into well‑defined AI and analytics solutions
• Design and develop machine learning, advanced analytics and Generative AI solutions for enterprise use cases
• Build and optimize RAG pipelines; work with LLMs, embeddings, vector databases, semantic search and reranking
• Design and implement AI agents integrated with enterprise applications and data platforms
• Evaluate models based on accuracy, latency, cost, privacy and infrastructure constraints
