Job Title for PreCompletion OPT, 1099

[titleseeker]

I just got a job offer in my state to work as an independent contractor in my field (my OPT has been approved for a while).

The company is letting me pick my job title. Does it have to have "trainee" "student" "intern" "apprentice" etc. in the job title, or is anything fine so long as it's clear that it's in my field of study?

Thanks
