"hire a Master Plumber with a team of juniors to fix it"
In that situation I would consider the "Master Plumber" akin to a lead developer or project manager. Which goes back to my main point - in software development you eventually need to either move to a management/leadership role or specialise in domain specific fields like security, computer graphics, systems architecture etc.
