In my totally unscientific survey of remote-friendly jobs over the past few years the majority appear to be webdev of some flavor, followed by devops of some flavor. There's an occasional Java, Go, or Rust position thrown in there as well.

Now, I don't see any variation in the stacks for webdev or devops jobs with respect to whether the job is remote or not. The significant bias in specializations available remote, though, significantly biases the overall stacks available.
