The Engineer is a Career in the Age of Rebellion Core Rulebook.
There would be no Galactic Civil War if not for the massive technological capabilities of both the Empire and the Alliance. Machines of every type are employed across great distances to hammer away at the enemy. These machines are imagined, designed, and built by Engineers, and Engineers are the ones who know how to keep them running – or to stop them cold.
Quarrie, R2-D2, and Galen Erso are all examples of Engineers in Star Wars.
