• Build and deploy generative AI applications using Python and AI/ML frameworks such as PyTorch, TensorFlow, and Hugging Face Transformers.
• Develop Retrieval-Augmented Generation (RAG) pipelines by integrating vector databases, embeddings, semantic search, and knowledge retrieval systems.
• Implement and manage agent orchestration workflows using frameworks such as LangChain, LlamaIndex, AutoGen, CrewAI, or similar multi-agent systems.
• Conduct data preprocessing, feature engineering, and dataset preparation to support model training, fine-tuning, and evaluation.
• Collaborate with engineering and product teams to integrate AI models and agent-based systems into production-grade applications and APIs.
• Evaluate model and system performance using relevant metrics, and continuously improve accuracy, latency, scalability, and cost efficiency.
• Design prompt strategies, guardrails, and monitoring approaches to ensure reliable and safe LLM outputs.
• Stay current with the latest advancements in generative AI, LLM architecture, RAG, AI agents, and emerging research trends.
• Ensure compliance with ethical AI principles, security standards, and data privacy regulations throughout the AI development lifecycle.

• Proven experience in developing, fine-tuning, and deploying large language models such as GPT, BERT, T5, LLaMA, or similar architectures.
• Strong programming skills in Python with experience building AI/ML solutions in production environments.
• Hands-on experience with AI/ML frameworks such as PyTorch, TensorFlow, and Hugging Face.
• Solid understanding of natural language processing (NLP) concepts, prompt engineering, model evaluation, and fine-tuning techniques.
• Experience designing and implementing RAG architectures, including embeddings, vector stores, document chunking, retrieval strategies, and grounding mechanisms.
• Familiarity with agent orchestration frameworks and building multi-step or multi-agent AI workflows.
• Experience with API development, microservices, and integrating AI capabilities into enterprise systems.
• Working knowledge of cloud platforms such as AWS, GCP, or Azure for scalable AI deployment.
• Strong analytical thinking, problem-solving ability, and effective collaboration skills.
• Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or a related field. Ph.D. is a plus.
