Restrict job titles that can be selected

[Mcgurk-Adam]

Is your feature request related to a problem? Please Describe: We don't want anybody to just be able to put any job title for themselves. It decreases the look and feel of the brand when for one specific job title there are, like, 20 different job titles floating around, all with little variations on top of one another.

Describe the solution you would like: An API that you query that returns the allowed job titles, then on the backend, a simple admin platform that allows you to edit the job titles that can be returned.

Additional Context: It's not a super important feature, but definitely one to implement in the future.
