I don't think startup job titles are worth much but they can be massive skill accelerators.

If you're in the first 5 years of your career you'll have more opportunity to learn more technologies at a small startup where everyone has to do everything than at a FAANG (especially compared to Google where you will only learn the Google internal stack).

You can leverage that into a much higher paying job in a way that you wouldn't be able to leverage experience at a mid-level company.
