This is something worrying me, looking for a junior role. I was a teacher for 5 years (math and physics) and recently went back to get a masters in Theoretical Physics and Applied Maths, mostly leaning towards the latter. Lots of data science-y stuff and mathematical modelling. Been applying to jobs for a while now, and no luck unfortunately. Wondering if I should just give up and go back to teaching, especially as I can return to my old school which was laid back and not horrible (and I didn't hate teaching), or keep pushing through. I've got a runway of about a year, depending on how reasonable the housing I can find in Ireland is (not very). Part of my issue is I'm also looking in Ireland, where I'll require a visa, even if it's a critical needs job so they're easier to get. Does hurt, but I haven't had any luck with my applications in America either.
