'Professional educator' isn't really a problem, although it's just a longer businessified 'professor' or ' teacher'

But 'educational operator' is another one of those signifiers of the breakdown of the world into 'consultants', 'managers', 'engineers' and 'operators'. Where consultants give ideas to managers for engineers to design which are then used by operators. Which creates a hell of a lot of distinctions where there is generally more overlap.

Hell, saying they worked on 'improvement of communication technologies for teaching' is better because it is more distinct and less technocratic.
