ML Engineer vs Data Scientist
ML Engineers and Data Scientists often work side by side, but their responsibilities differ in a critical way. Data Scientists design and evaluate models — the research and experimentation layer. ML Engineers take those models and build the systems to deploy, serve and monitor them in production. The distinction matters more as teams grow, and the hiring market reflects it clearly in skills required and pay.
