I can confirm that at the mechanical hardware level you'd also typically have specializations. At the very least I'd see one design engineer (CAD, designing parts for manufacturability, selecting COTS systems based on requirements) and a controls engineer (simulating and analyzing kinematics and dynamics of moving parts and setting up the controls algorithms to be used). One jack-of-all trades engineer could for sure do both, but in larger projects with high budget (BD, NASA rovers, etc), you'd have even more different specializations just in mechanical engineering: thermals, structural analysts, motorization experts, etc.
