Atmos techs are probably usually the first ones to deal with most breaches and fires and such, things that would be need the damage to be controlled before properly fixed, such as setting up inflatables, fighting fires, etc. Comparatively to engineers, atmos techs having work to do is probably emergency response most of the time, with most of the non-emergency work being stuff engineers would do, and a decent portion of atmos tech duties would make sense for what DCTs do IRL. Not all, but some.
That being said, I do second that DCT will be mostly confusing, since engineers still do some damage control (in fact, its common from what Ive noticed for "kits" for engineers to be called "damage control kits" by other engineers), and I think most people wouldnt relate it to atmos at first glance. Maybe itll be fine and people will be adjusted for it over timeee, but it might not be the most clear for the average person.
