Job summary

EXL is seeking an experienced LLM/GenAI engineer to design and implement AI-powered business solutions. You will build RAG pipelines, integrate LLMs with enterprise data, and develop production-grade APIs using Python frameworks.

The role emphasizes collaboration with cross-functional teams and a focus on data quality and governance. Applicants should have 2–4 years of AI/ML or data engineering experience, with hands-on exposure to LLM/GenAI use cases and cloud platform experience.

Qualifications

• 2–4 years total experience in AI/ML or data projects.
• Hands-on experience or strong exposure to LLM/GenAI use cases (projects, POCs, academic work, or professional).
• Proficient Python programming and API development for production systems.
• Experience with cloud platforms (Azure/AWS/GCP) is a plus.

Responsibilities

• Design and develop LLM-based solutions for business use cases (chatbots, summarisation, document intelligence).
• Build and optimise RAG pipelines including data ingestion, embeddings, and retrieval.
• Implement prompt engineering techniques and tuning.
• Develop backend services/APIs for AI applications using Python frameworks (FastAPI/Flask/Streamlit).
• Integrate LLM solutions with enterprise data sources.
• Apply guardrails and evaluation techniques to improve response quality and reduce hallucinations.
• Collaborate with cross-functional teams to ensure data quality and deployment readiness.
• Document solutions and contribute to reusable components and best practices.
