Chief engineer is a senior staff position aboard a Federation starship, the officer (or noncommissioned officer) charged with responsibility for the operation and maintenance of the ship's power, environmental, and other key systems. (ST reference: Star Trek Encyclopedia)

First engineer is sometimes used as translation of Romulan language terminology for the chief engineer of a starship. (TOS novel: Vulcan's Heart)
