Impeller Technicians operate, maintain, and repair ship's propulsion systems. This includes manning the ship's impeller rooms and care for hyper drive generators and Alpha and Beta impeller nodes. Impeller Technicians fall under the Propulsion Group within the Engineering Department.[1]

Historical Overview

The closest real-world parallels would be the USN's wikipedia:Machinist's Mate: Machinist's Mate (MM) and Gas Turbine System Technician (GS) ratings. Both of these ratings are focused on operation and maintenance of main propulsion systems, either steam (including nuclear), or gas turbines. The scope of their responsibility encompasses the entire main propulsion system - engines, gearboxes, main shafts, propellers - as well as supporting ancilliary systems such as fuel boost pumps, air compressors, main lubricating oil systems, as well as related control systems and instrumentation.

Similarly, in the Royal Navy, the equivalent to an Impeller Technician would be the Engineering Technician[2], and in the Royal Canadian Navy, the Marine Engineer[3] trade.
