A space bridge technician is a specialist in the field of space bridge maintenance and construction.
Upon his entry into the Autobot boot camp, Bulkhead announced that he simply wanted to become a space bridge technician, a goal that made the others in his unit laugh. Since it's considered to be a quite unpopular and less glorious job by most bots.
