How do I make a list with repeating entries?

Essentially, I want a formula which creates a list of jobs based on the value given to that job.

Here's an example.

I have a column for jobs which lists Barista and Manager. Then a column for the number of that job that is available, which says there are 3 barista positions and 1 manager position.

The formula I'm trying to have should make a list that repeats "Barista" 3 times and only lists manager once. How would I do this?
