Sorta. The basis for your concern underlines one of the problems. When such gaffs happen in engineering, the firm is blamed. Within the firm, individual actors are blamed.
In software, on the other hand, your major system might have responsibility for a critical system spread across a total of 1 persons, so he gets all the blame. Is that really okay for one hip-shooter to take this on in the first place?
The liability sits with your employer.
