The AI Lead Engineer will be responsible for integrating, fine-tuning, and operationalizing large language models and other AI components into production-grade software systems. This role focuses on post-training workflows—such as fine-tuning, prompt engineering, retrieval-augmented generation (RAG), vector database integration, and model deployment—rather than foundational model development.
