We don't put engines on top because it makes maintenance alot harder.

There's also the issue of ingesting the turbulent/detached boundary layer of the fuselage at high angles of attack, causing inlet distortions and the corresponding risk of compressor stall.

Also safety. Uncontained engine failures shouldn’t ever happen (and maybe happen less as technology gets better), but when they do happen, it’s better for them to be under the wing away from the fuselage rather than right in the path of critical control systems.

Since this is a blended wing with no vertical stabilizer, it might be different, but it does still look like there are control surfaces right next to the engines..

but.... all the control surfaces are on the wing right next to that engine.

Ailerons and flaps are, but elevators and rudder that control the yaw and pitch of an aircraft are in the tail. See United Flight 232.
