* The GenAI application framework ecosystem: including chaining, retrieval-augmented generation, autonomous agents, and vector search tools (e.g., LangChain, LlamaIndex, pgvector).

Compétences

You hold a degree from a top-tier engineering school, and we are looking for:
* 1-2 years of experience in a similar role.
