Your Responsibilities

Develop, train, and optimize ML models using PyTorch, TensorFlow, and Keras.
Build end-to-end LLM and RAG pipelines using LangChain and LangGraph.
Work with LLM APIs (OpenAI, Anthropic Claude, Azure OpenAI) and implement prompt engineering strategies.
Utilize Hugging Face Transformers for model fine-tuning and deployment.
Integrate embedding models for semantic search and retrieval systems.
Work with transformer-based architectures (BERT, GPT, LLaMA, Mistral) for production use cases.
Implement LLM evaluation frameworks (RAGAS, LangSmith) and performance optimization.
Implement real-time communication with FastAPI WebSockets.
Implement pgvector for embedding storage and similarity search with efficient indexing strategies.
Integrate vector databases (pgvector, Pinecone, Weaviate, FAISS, Milvus) for retrieval pipelines.
Containerize AI services with Docker and deploy on Kubernetes (EKS / GKE / AKS).
Configure AWS infrastructure (EC2, S3, RDS, SageMaker, Lambda, CloudWatch) for AI / ML workloads.
Version ML experiments using MLflow, Weights & Biases, or Neptune.
Deploy models using serving frameworks (TorchServe, BentoML, TensorFlow Serving).
Implement model monitoring, drift detection, and automated retraining pipelines.
Build CI / CD pipelines for automated testing and deployment with ≥80% test coverage (pytest).
Follow security best practices for AI systems (prompt injection prevention, data privacy, API key management).
Participate in code reviews, tech talks, and AI learning sessions.
Follow Agile / Scrum methodologies and Git best practices.
