True, but a senior engineer, even if he is never able to make architecture decisions, can still be held accountable for knowing better. That is precisely why they are paying him the big bucks.

If a shop is being held together with duct tape and elbow grease, then you should have known that going in, and developed personal habits to avoid this sort of thing. Being overworked and tired isn't an excuse. Sure, the company and investors have to bear the real consequences, but you as an IC can't disclaim responsibility.
