This person clearly isn't a senior. Either he should do it already or he should have realized his limits and asked for specific things he needed to accomplish his work (juniors often don't know what they need). Or he's in a difficult personal situation and can't think clearly (not sure this is your job to figure out though). I agree with other commenters: in the end you hired a senior so you wouldn't have to spend time teaching a junior. Be available to explain things he asks but give him time and space to figure out things on his own. Is it the very first month of employment? Maybe the onboarding wasn't great and he is bogged down trying to understand the big picture. You shouldn't be hand holding seniors with experience. Give him concrete goals, requirements and deadlines so he knows what he needs to deliver and let him do his thing. Also, review your hiring process.
