📋 Description

• Lead implementations involving Python, modern web architectures and Generative AI systems. • Design and build RAG (Retrieval-Augmented Generation) pipelines and deploy production-ready intelligent chatbots. • Ensure quality, performance and governance of AI workflows used by hundreds of thousands of educators. • Deliver web application development tasks in Python (FastAPI / Django / Flask) and integrate with modern front-end frameworks (React, Vue, etc.). • Design, implement and orchestrate end-to-end RAG pipelines: indexing, chunking, embeddings, vector stores, re-ranking and monitoring. • Create and evolve intelligent chatbots and agents capable of understanding context, executing tools and accessing internal data. • Instrument latency metrics, response quality, observability and continuous improvement loops for AI pipelines. • Collaborate as needed with cross-functional teams (product, research, content) to align requirements and define deliverables. • Automate and optimize data pipelines, external integrations and asynchronous processing tasks. • Build with recommendations and implement best practices for architecture, testing, versioning, security and AI governance.

🎯 Requirements
