I don't think he knows the end game, but I do think he knows that Cinder can control Grimm somewhat and that she plans to unleash them on the city. After all, he did say, "That's the plan" when Ruby pointed out that without the airships the Grimm would destroy the city. And there's something about that evil chuckle when Ironwood walks away from him at the end of Vol 2, like he knows the good guys are gonna get blindsided.
