From the announcement:
The Galactic Empire’s iron grip seems insurmountable. The most powerful war machines the galaxy has ever seen are opposed only by a relatively small number of courageous souls. But the bravery of Soldiers and ingenuity of Commanders would be like a gentle breeze against the mightiest trees of Kashyyyk without the tireless work of every Engineer in the Rebel Alliance. Blasters and bombs, starfighters and secret bases, repurposed datapads and rebuilt droids—Engineers transform the noble ideals of the Rebellion into action with every turn of the spanner.
Fantasy Flight Games is excited to announce its next release for the Star Wars™: Age of Rebellion Roleplaying Game™. Fully Operational, the career sourcebook for Engineers, expands the resources available to players and gamemasters alike with new talent specializations, species, potent Signature Abilities, gear, and campaign enhancements perfect for those with a proclivity for tinkering, repairing, and constructing.
