Location

Pune / Gurgaon (Gurugram) / Bangalore (Hybrid)

About EXL

EXL has evolved from business process services into a global leader in Data and AI , partnering across industries such as insurance, healthcare, banking & capital markets, retail, media & communications, and energy & infrastructure.

Job Summary

We are looking for highly capable Agentic / Generative AI Engineers to design, build, and deploy LLM-powered and agentic systems for enterprise use cases—such as knowledge assistants, document automation, summarisation, and intelligent workflow orchestration. You will work closely with data engineers, data scientists, MLOps, and product teams to deliver secure, scalable, and measurable GenAI solutions.

Mandatory: Prior experience in Data Engineering or Data Science (strong foundations in data pipelines, ML lifecycle, or analytics engineering).

Key Responsibilities

• Design and build agentic LLM solutions (single- and multi-agent patterns) to solve real business problems across domains (e.g., customer support, document intelligence, knowledge retrieval).

• Build RAG pipelines end-to-end: data ingestion → chunking/embeddings → vector search → retrieval orchestration → response synthesis, with measurable quality.

• Implement prompt engineering and prompt orchestration (prompt chains, tool-calling, function calling), including prompt iteration and cost/latency optimisation.

• Develop production services/APIs for LLM applications (e.g., FastAPI/Flask/Streamlit ) and integrate with enterprise systems and data sources.

• Apply guardrails to reduce hallucinations, enforce policy constraints, and ensure safe tool usage; implement evaluation strategies for LLM and RAG outputs.

• Collaborate with Data Engineering teams to ensure data quality, governance, and documentation standards , and with MLOps/Platform teams for CI/CD, monitoring, and reliable deployments.

• Create and maintain technical documentation, solution design artefacts, and reusable components for faster delivery and consistent engineering practices.

Must-Have Skills

5 to 12 years total experience, with hands-on LLM/GenAI delivery experience (preferably 1–3+ years building production-grade LLM apps).

LLM / GenAI & Agentic Engineering

• Hands-on experience with LLMs including Claude (Anthropic) and other leading models; strong understanding of capabilities, limitations, and use-case fit.

• Practical experience with RAG , embeddings, vector databases (e.g., FAISS/Pinecone/ChromaDB), semantic search, and retrieval quality evaluation.

• Experience with frameworks/tools such as LangChain, LangGraph , Hugging Face, or equivalent orchestration stacks.

• Experience building agentic workflows including tool calling/function calling; familiarity with “agentic architecture” concepts is valued.

• Exposure to Claude Code or similar coding-agent workflows is a plus (agentic coding that can work across codebases, run tests, and iterate).

Core Engineering

• Strong Python engineering skills (production-grade coding, testing, packaging, API development).

• Solid understanding of cloud platforms (Azure/AWS/GCP) and deployment basics (containers, CI/CD, monitoring).

• Strong communication skills—ability to translate business needs into technical solutions and articulate trade-offs clearly.

Mandatory Background (Non-negotiable)

• Prior experience in Data Engineering or Data Science :

  • Data pipelines / ETL / ELT / orchestration, or

  • ML/NLP modelling lifecycle, experimentation, evaluation, or

  • Analytics engineering and data product delivery.

Good-to-Have / Preferred

• Fine-tuning approaches (e.g., LoRA/PEFT ), prompt tuning, few-shot strategies, and model evaluation methods.

• Experience with enterprise-grade privacy/security considerations for GenAI solutions (data handling, redaction, access control).

• Experience with Azure stack components often used in GenAI (e.g., Azure AI Search / Azure OpenAI) is beneficial.

Education

Bachelor’s or Master’s degree in Computer Science, Data Engineering, Data Science, Information Systems, or related fields (or equivalent practical experience).
