Job Description

Key Responsibilities

  • Design and develop LLM-based applications using single-agent or simple multi-agent patterns for business use cases
  • Build and maintain RAG pipelines data ingestion → chunking → embeddings → retrieval → response generation
  • Implement prompt engineering techniques (prompt templates, chaining, basic tool/function calling)
  • Develop backend services/APIs for AI applications using Python frameworks (FastAPI / Flask / Streamlit)
  • Integrate AI solutions with enterprise systems, databases, and APIs
  • Apply basic guardrails and validation checks to improve response quality and reduce hallucination
  • Work with Data Engineering teams to ensure data quality, pipeline efficiency, and proper documentation
  • Collaborate with MLOps teams for deployment, monitoring, and iterative improvements
  • Document solutions, reusable components, and best practices

Must-Have Skills
