The rest will be spent designing data structures and pipelines for AI (vector store, RAG‑style data access) and, if it makes sense, basic semantic models / SSAS.

Infrastructure / IT will manage servers, OS, and patching. You own schema, code, performance, ETL, and data models. You’ll be expected to make architecture decisions, challenge assumptions, and push for robust, maintainable solutions.
