Why LinkedIn Feed Posts Are Better for LLM Roles

LLM Engineer is so new that many companies do not have a formal job description template for it. Founders and CTOs post directly to their LinkedIn feed: "We need someone who knows LangChain and RAG — email me." These posts have almost no competition because most job seekers are still checking job boards.
