As a manager? Coach your report on his soft skills. Software dev is about being a good team member as much as a good individual contributor. If the strongest guy is dominating meetings and dominating the team's direction with his opinion, that's something to work on.

He has to give others space to contribute by not jumping in. And his manager should be coaching this directly. As the EM, you want your whole team to be able to confidently do what he does. Functioning teams have multiple engineers concurrently owning your scope.

If your company isn't toxic, over-working would also be seen as a negative because of the precedent it sets. If this guy wants to be a leader and not a monkey, he has to appreciate that. And senior/staff counts as "leader" here.
