I used[1] jetbrains tooling quite a bit on my m1 air and never had problems, though I did opt for the 16gb ram version. The newer models are presumably at least as performant if not better?
([1] These days my daily driver is an m1 mbp of some whizzbang 32gb variety, which only replaced the mba because my spouse wanted a travel machine and the mbp came for the low low cost of being caught in the late 2022 startup crash. For day to day ordinary backend dev work there really isn't a noticeable difference in my experience, except I guess the mbp is more awkward when working-from-couch. arm vs x86 was sometimes a little awkward around launch, but I can't remember the last time it was an actual hassle.)
