Hi,
the title "Junior publicist" is often categorized into "public relations" (
here):
duties include preparing and distributing information to the media, including press kits, media alerts, clips for talk show appearances, photography and html e-mails. Also responsible for talent travel arrangements and hair and make-up booking; coordinating episode dubbing and press mailings, maintaining budgets and processing invoices; creating materials such as contact sheets, cast i.d. sheets and bios...
Sometimes they write the title as
PR Assistant/Junior Publicist
Here they want him to have a degree or diploma in film studies, journalism or communications/public relations OR
In Italian???
Qui: l'adetto alle pubbliche relazioni, comunicatore d'impresa, adetto all'ufficio stampa (quello è più simile a giornalista...)
Forse potrebbe andare "adetto stampa e relazioni pubbliche"??? Junior???
