Actually, there is no "job of 'journalists'" in the Constitution.
The "free press" is the right of the people to a free press, that is, the right to publish. The "press" literally meant the machine, the printing press. The people had the right to publish freely to expand the reach of their speech beyond the town square soapbox.
The term "the press" to refer to newspapers and periodicals didn't begin until the 1820s, and referring to journalists didn't begin until the 1920s.
