I'm a software developer, so there's a lot of WFH positions at least compared to other fields. But unless you have particularly good connections you would probably need to get a related degree if you wanted a job at most places. I've also heard it's not a good time to be applying unfortunately. You might be able to try for some WFH consulting work related to your current job. Big software companies will hire contractors for temporary work too I guess, but they would probably still want experienced candidates. For me, this was just a position I applied to a few years ago and was lucky enough to get an offer. I don't think there's a secret to it, sorry.
