The Senior Manager will guide the end‑to‑end technical approach for AI use cases, determining the optimal methodologies to balance cost, complexity, efficiency, and business value. This role requires hands‑on expertise with data engineering and data science technologies, including SQL, Python, ML frameworks, and experience working with LLMs and retrieval‑augmented generation (RAG) patterns.
