The Technician is a Career in the Edge of the Empire Core Rulebook.
Pretty much anything to do with technology or mechanical devices lies within the Technician’s purview. They know how to operate, maintain, repair, and upgrade just about anything with power or gears. Most Technicians would rather deal with machines and droids than people; the rather are just too unpredictable.
Chewbacca, “Chopper”, and Anakin Skywalker are examples of Technicians in Star Wars.
