Key Responsibilities - Design and develop LLM-powered applications using agentic patterns (single/multi-agent) for business use cases
Build and optimise end-to-end RAG pipelines (ingestion, embeddings, retrieval, orchestration, response synthesis)
Implement prompt engineering and orchestration techniques (prompt chaining, tool/function calling, structured outputs)
Develop production-grade APIs and services (FastAPI/Flask/Streamlit) for GenAI applications
Integrate LLM solutions with enterprise systems, data platforms, and workflows
Apply guardrails and evaluation frameworks to improve response quality, reduce hallucinations, and ensure responsible AI usage
Collaborate with Data Engineering and MLOps teams for data pipelines, deployment, monitoring, and scaling
Contribute to reusable components, documentation, and engineering best practices Experience & Core Requirements (Must-Have) Overall Experience - 6–9 years total experience
