Before the Omnic Crisis, Torbjörn had gained notoriety for designing weapons systems used by countries around the world. However, his belief that technology must serve a better vision for humanity put him at odds with his employers, who desired to control his weapons using networked computer intelligence. At some point he worked with the Ironclad Guild, where he worked in R&D.

Torbjörn had a deep mistrust of sentient robotic intelligence, and while many of his peers wrote this off as paranoia, his worst fears were realized when the robot populations of the world turned against their human creators during the Omnic Crisis. Because of his engineering genius, he was recruited to join the original Overwatch strike team, and his many inventions proved integral to ending the conflict.
