[Pulp Fiction] Was Jimmy a hitman?

Jules considered him a partner, but did he mean a partner in profession, or a trusted friend?

Marcellus' organisation doesn't seem to employ dedicated hitmen, but mostly people with various criminal talents he uses in different contexts. Neither Jules nor Vincent are simply hitmen, even though that is their main function in the beginning of the movie. Winston's main function is to be a "problem solver", even though that problem might have been people needing to disappear every now and then. Marcellus can apparently get hold of a number of pipe-hitting gentleman who know their way around some pliers and blowtorches within the hour, although they're neither dedicated killers nor torturers.

Jimmy is most certainly a criminal partner of Jules, but not primarily in directly violent endeavours, given how freaked out he is about the presence of a corpse at his house, how freaked out he is at the thought of his criminal life impacting his marriage or how downright submissive he becomes when meeting a known figure like Wolf. 

I'd assume Jimmy is mostly a bookey, smuggler, fence or something else that is definitely criminal, but not very physical.
