Some advice that has taken me over a decade to learn myself:
There are no rules, the titles are made up, the responsibilities and requirements do no matter.
Get what you can from your job, and once you get something do your Best even if that best sucks, and stay until you have gotten what you want out of the job, or realize you can’t or don’t want to do it anymore, and then start again doing something else.
Don’t ever limit yourself thinking you need to “level up” or something needs to get unlocked.
Learn by doing, try your best, you will make things that suck sometimes, but as you do more and more you should be making things better.
