Engineering
On any space starship, engineers are officers assigned to monitor and maintain the starship's functionality. They are designated with gold-trimmed uniforms and often do most of the "grunt work" that is involved in keeping a ship or space station up and running. Engineering officers are generally assigned tasks that include maintaining and/or improving the performance of the warp drive, ship’s database, computer processors and circuitry, holographic emitters, tractor beams, transporter components, observational equipment (such as sensors, probes, and satellites), weaponry systems, deflector array, hull plating, life support, shields and alternative defense systems, and many other crucial parts of a ship’s anatomy. They are expected to tackle all the problems that drain the ship’s resources or lower its efficiency.
On a Starfleet vessel of any kind, the chain of command in the engineering department tends to be simple with smaller teams broken apart from the whole. A chief engineer and an assisting officer lead the entire engineering team, often delegating tasks to smaller teams formed within the whole. Because the operations of a starship, starbase or space station are so complex, the engineering department runs routine maintenance on all ship systems. Tests are done regularly through main engineering, which is the hub of activity for the entire department. From main engineering, all ship functions can be monitored and checked for any abnormalities.
Major logistical tasks are addressed by the Starfleet Corps of Engineers.
The Starfleet Corps of Engineers (also known as Starfleet Engineering or Starfleet Engineering Corps) is a Starfleet division that deals with specialized engineering problems.
The Corps of Engineers was responsible for the construction of the underground laboratory complex on the Regula asteroid, where the second phase of the Genesis Project was conducted. (Star Trek II: The Wrath of Khan)
In an alternate reality experienced by Harry Kim in 2372, he worked at the Starfleet Engineering Corps. (VOY: "Non Sequitur")
In 2375, during the Dominion War, Klingon starships could be made immune to the Breen energy dampening weapon by adjusting the tritium intermix of their ships' warp cores. This "fix" would not work on Federation ships and Starfleet Chief Miles O'Brien forwarded his findings to Starfleet Engineering for more in-depth analyses. (DS9: "When It Rains...")
In 2377, Captain Kathryn Janeway lamented that they didn't have a Corps of Engineers to build a planet-wide system of atmospheric processors to decontaminate Brin's homeworld. (VOY: "Friendship One")
