AI Engineer

AI Engineers are the hottest new role in tech. They bridge the gap between foundation model capabilities and real product value. Unlike ML Engineers who build models from scratch, AI Engineers focus on integrating pre-trained LLMs into applications using techniques like RAG, fine-tuning, and agent architectures. The demand has exploded since 2023, and companies across every industry are hiring AI Engineers to build intelligent features into their products.
