Artificial Intelligence Specialist

Work Location: Chennai (Work from Office)

Role Overview

We’re hiring an NLP/LLM Engineer to design production-ready NLP pipelines, fine-tune open-source LLMs, and integrate LLMs into real-time products. You’ll work with product teams to build classification, NER, summarization, sentiment, and QA systems — from data preprocessing to deployment and monitoring.

Responsibilities

• Design and implement NLP pipelines for classification, NER, summarization, sentiment analysis, and Q&A (RAG).
• Preprocess and structure large-scale textual datasets using SpaCy, NLTK, or custom tokenizers.
• Fine-tune and optimize open-source models (BERT, T5, GPT-style) using Hugging Face Transformers.
• Integrate LLM APIs (OpenAI, Anthropic/Claude, Cohere, Hugging Face) into real-time applications and microservices.
• Develop prompt strategies and evaluate prompt robustness; implement few/zero-shot approaches where relevant.
• Build retrieval + generation (RAG) pipelines with vector DBs (FAISS, Weaviate, Pinecone).
• Deploy model endpoints (Flask/FastAPI/Streamlit), containerize with Docker, and collaborate on cloud deployment.
• Monitor model performance, data drift, and user feedback; iterate based on metrics and qualitative signals.
• Collaborate with product, infra, and QA to embed models safely and responsibly.

Required skills & experience

• Strong Python skills and experience with SpaCy, Transformers (Hugging Face), and NLTK.
• Hands-on experience fine-tuning/training Transformer models (BERT, T5, GPT variants).
• Experience integrating LLM APIs and working with prompt engineering.
• Familiarity with embeddings, attention, tokenization, and vector similarity (cosine).
• Experience with vector DBs such as FAISS, Weaviate, or Pinecone.
• Comfortable with Docker, Git, and REST API development (Flask/FastAPI).
• Practical knowledge of evaluation metrics (BLEU, ROUGE, perplexity, cosine similarity).

For Sr. Roles: In addition to the above,

• Track record of shipping multiple production LLM/NLP systems end-to-end.
• Strong system design skills (latency/cost tradeoffs, multi-tenant inference).
• Mentoring/leadership experience and ownership of ML lifecycle (MLOps).

Preferred / nice-to-have

• Experience with LangChain, LlamaIndex, PromptLayer, or similar LLMOps tooling.
• RAG workflows and building retrieval pipelines at scale.
• Experience in cloud deployment on AWS/GCP/Azure.
• Contributions to open-source projects or research publications.
