AI Engineer / Data Scientist - NLP & Generative AI

Experience: 6-7 years

Location: India

Role Summary

Build and productionize NLP and generative AI capabilities - from classical NLP through LLM-based agentic workflows - for real-time, high-scale enterprise applications, with a focus on prompt engineering, RAG, and conversational AI experiences.

Key Responsibilities

Design, fine-tune, and optimize prompts for production LLM features (summarization, classification, sentiment, Q&A, translation, knowledge-gap analysis)

Build agentic workflows (e.g., CrewAI, LangChain, LangGraph, or equivalent) to orchestrate RAG pipelines and multi-step evaluation/validation tasks

Apply classical NLP techniques (clustering, sentiment analysis, NER, topic modeling, text classification) using transformer models alongside LLMs where appropriate

Develop and deploy real-time inference APIs to serve AI features to production applications at scale

Integrate speech-to-text and text-to-speech capabilities for conversational/simulation use cases

Build monitoring/analytics pipelines for productivity and quality metrics derived from AI outputs

Iterate on model performance through hyperparameter tuning, feedback loops, and evaluation against production data

Work across open-source and hosted LLMs, selecting the right model/deployment for cost, latency, and accuracy needs

Partner with data engineering on ingestion/synchronization pipelines across relational and vector data stores

Present KPI metrics, model performance, and insights to business stakeholders via dashboards

Required Skills & Experience

6+ years in NLP / data science / AI engineering with production deployment experience

Strong Python experience serving ML/AI models via production APIs

NLP fundamentals: text classification, NER, clustering, topic modeling, summarization, sentiment analysis

Transformer model experience: BERT/RoBERTa/T5/BART or equivalent

LLM and agentic tooling: prompt engineering, RAG, agentic frameworks (e.g., CrewAI, LangChain, LangGraph), and LLM APIs (e.g., GPT, Claude, or open-source models)

Classical ML: supervised/unsupervised algorithms and evaluation methodology

Hands-on depth with Azure AI and compute services - Azure AI Foundry, Azure Function Apps, Azure Logic Apps - or equivalent AWS/GCP AI and serverless stacks

SQL databases plus exposure to a vector store

Preferred

Knowledge graph / graph-based retrieval techniques for RAG (e.g., Neo4j or equivalent)

Production deployment experience across multiple major cloud platforms (AWS, Azure, and GCP) - spanning AI/ML services, managed databases, and serverless compute

Speech-to-text/text-to-speech integration experience for conversational AI use cases

Experience with no-code/low-code platforms (e.g., Microsoft Power Platform, Copilot Studio, or equivalent) for rapid agent/bot prototyping

Dashboarding (Power BI/Tableau)

Exposure to healthcare or other regulated-data domains

Education

Bachelor's/master's in data science, Computer Science, Statistics, or related field
