You develop with Claude Code or Cursor open 24/7, you move faster than your shadow and you think that AI will completely redefine the profession of developer?
Welcome to SFEIR Nantes!
🧠 What we’re looking for in you

build AI APIs with Python, FastAPI, LangChain, LiteLLM or LangGraph,
think about orchestration, RAG, AI agents, vectorization, evaluation, FinOps and observability,

You want to understand how models work. Not just consuming APIs.
🛠️ Projects you could have fun with
Build cloud-native GenAI platforms on Google Cloud,
Develop AI assistants connected to our clients’ business tools,
