Not the GP but it's nigh on impossible for an EM to do their job. Roughly speaking they are supposed to be the voice of developers/engineering. But since they are not hands on the code they don't know the reality of the code base and so can't be an effective advocate. Ultimately they end up being a relayer of messages.

I think the role needs to exist but it's not a per team role. You need one for every 4 teams or so. They're there to build the teams, make sure they're running right, and do the high level resource allocation. Day to day management of the team should be a collaboration between a lead developer and a product owner.

Maybe part of the problem is there is no consensus on what an EM "should" be doing. Note that the comment above this one gives a much different synopsis of the role.
