I did the following:
1) went to Beaver Builder -> Saved Modules
-- hidden link
2) translated both jobs engineering and jobs operations to Spanish
As for "Responsibilities will include, but not be limited to the following:" and "READ MORE", these don't seem to be stored on the page content.
However, when I opened this: hidden link
So jobs engineering while in Spanish language, and when I launch the Beaver builder, I do see them there (Edit custom post layout). I tried changing this and it seems to be working properly, so the translation is showing there now. You can also do this for custom layout controlling what is showing up on Operaciones.
