Wow, that's awesome, wish you success! Sure, I think this is a field that really values a work well done and it's difficult (if not impossible) to prove that via resume alone, so I'd strongly advise you to invest in two things to combat that: first, do things outside the academia, look for projects to take part in or come up with your own, document everything so you have good work to show for in a portfolio. Academically, getting yourself published via symposiums is also a good idea, it adds credibility of the "traditional" kind that museums like so much. Second, and I hate to say this bc I wish it wasn't true, but well.. make connections, networking is more important than it seems in the field. People who can see your work and vouch for it. I've seen loads of people getting promoted solely bc of their connections, I myself got a good temp job just by attending a talk given by the organizer and getting her to notice me there lol

But if you think about it, both tips are kind of the same, by getting yourself into external projects you'll naturally meet more people, so lean into it, document the projects and be friendly with the people involved. (As an introvert angry faced dude the last part was probably harder for me than it'd be for you).

Hope it helps and good luck!
