OSS is the easiest to break into, just work on your own OSS and then you're into it that's it
I did computer support for one of them. The projects were great and I almost moved "up the hill" to a national lab.
I have zero knowledge of openings, but there is a giant need of support to organizations fighting the destruction of such labs and of democracy itself. If I knew a suitable opening, I'd work there for free (I'm retired and looking out only for younger people at this point.)
