Is journalist uncountable?

[Jonifa]

Hello,

Here:
Home > English as a Second Language > English Errors, Elementary Level # 17

we can read:
"I have a very interesting job because as a journalist I meet many people."

My doubt is: ?Is journalist uncountable?
It is "a journalist" correct or it should be without "a"

Thanks in advanced !!

Journalists, like taxi drivers, teachers,veterinarians and countless other occupations, are countable.
