AI Agent Evaluation Developer for RAG

# AI Agent Evaluation Developer for RAG Document Workflow POC We are looking for a developer to build a small document agent and evaluate it using Braintrust or Plumloom. We will provide one large PDF or Markdown document. The agent should: * Answer questions about the document * Search the document multiple times when needed * Refine searches when evidence is incomplete * Generate a structured report or brief with citations * Capture the full agent trace Google ADK is preferred, but LangChain or another open-source framework is acceptable. You are free to design the chat interface using AI tools of your choice.
