📋 Description

• Lead implementations involving Python, modern web architectures and Generative AI systems. • Design and build RAG pipelines, create production-ready intelligent chatbots and ensure quality, performance and governance of AI workflows. • Deliver web application development in Python (FastAPI / Django / Flask) and integrate with modern front-ends (React, Vue, etc.). • Design, implement and orchestrate complete RAG (Retrieval-Augmented Generation) pipelines: indexing, chunking, embeddings, vectors, reranking and monitoring. • Develop and evolve intelligent chatbots and agents capable of interpreting context, executing tools and accessing internal data. • Build Generative AI workflows using LangGraph, LangChain, LangFuse, OpenAI, Hugging Face, etc. • Instrument metrics for latency, response quality, observability and continuous improvement loops in AI pipelines. • Collaborate as needed with multidisciplinary teams (product, research, content) to align requirements and define deliverables. • Automate and optimize data pipelines, external integrations and asynchronous processing tasks. • Build following recommended best practices for architecture, testing, versioning, security and AI governance.

🎯 Requirements

• Strong command of Python and software architecture (APIs, distributed services, modularity, testing). • Experience developing web applications and integrating front-ends with APIs. • Hands-on experience with Generative AI (not just experimentation): embeddings, LLMs, tool functions, prompts and agents. • Solid understanding of relational and non-relational databases, caching, queues and asynchronous pipelines. • Proficiency with Git, CI/CD and cloud environments. • Nice-to-haves: prior experience with LangGraph, LangChain, LangFuse, Qdrant, Pinecone or similar technologies. • Proven experience building end-to-end RAG (indexing → querying → evaluation). • Experience with agent-oriented architectures. • Advanced full-stack development (React / Vue). • Previous experience with educational products, social impact initiatives or large-scale systems. • Experience with LLM quality monitoring and A/B testing of prompts.
