RAG Engineer — Role Alloy

The RAG Engineer alloy is the job-role composition for people who build and operate retrieval-augmented systems end to end — where the work is as much data engineering as it is modelling. It binds the data pipeline (ingestion, chunking, embeddings, vector indexing, freshness), the retrieval and grounding skills that make answers faithful, and the evaluation discipline that proves retrieval quality rather than assuming it. Pursued as an Alloy, it routes you through only the elements you have not yet demonstrated and tracks each against your evidence graph, so "RAG Engineer" becomes provable, not just claimed.
