• Collaboration: Work closely with data scientists, AI engineers, and frontend developers to translate business requirements into efficient data models and technical solutions.
• Best Practices: Contribute to setting standards and best practices for SQL performance tuning, database architecture, ORDS configuration, and APEX development.

Essential Skills

• AI/ML Foundations: Familiarity with modern AI concepts, including the application of LLMs, RAG, and core machine learning methods (clustering, classification).
• Oracle Vector Database Capabilities: Practical knowledge of using Vector Embeddings and the JSON Relational Duality (JRD) views for efficient storage, indexing, and retrieval of unstructured data chunks (documents, text, images).
