Lockdown and Harold Attinger are both the main antagonists of Age of Extinction; Lockdown was hired by the "Creators" to capture Optimus. Also Lockdown has a larger role in the climax then Attinger; he fights Optimus Prime, Attinger does not. So what really it is is that Lockdown works "with" Attinger, not "for" him.

Another thing; the filmmakers and wikipedia (the main wiki) have directly stated that Galvatron (Megatron reincarnated) is the secondary antagonist of the film. They have also directly stated that Lockdown and Attinger and both the main antagonists.
