Python Engineer - AI/ML & LLM Specialist

Seeking a hands-on Python Engineer with strong expertise in AI/ML, NLP, and Large Language Models (LLMs) to build and deploy production-grade AI applications. The role involves designing scalable LLM systems, developing RAG pipelines, fine-tuning transformer models, and building end-to-end ML infrastructure for real-world business applications.

Responsibilities

• Design and build AI/ML systems focused on NLP and LLM-powered applications such as chatbots, summarization, classification, semantic search, and entity extraction.
• Fine-tune and optimize LLMs including LLaMA, Mistral, GPT variants, and transformer-based models using LoRA, PEFT, RLHF, and prompt engineering techniques.
• Build and implement RAG (Retrieval-Augmented Generation) pipelines integrated with vector databases like Pinecone, Weaviate, ChromaDB, and FAISS.
• Develop scalable ML pipelines covering preprocessing, model training, evaluation, deployment, monitoring, and retraining.
• Optimize model inference using quantization, pruning, batching, and performance tuning techniques.
• Build REST APIs and microservices using FastAPI or Flask for AI model deployment.
• Collaborate with product, engineering, and data teams to deliver scalable AI solutions.
• Maintain experiment tracking, model versioning, and MLOps workflows.
• Stay updated with emerging LLM technologies, frameworks, and AI tooling.
