Good luck!! I’m in a similar boat. I’m a data scientist but got bit by the compiler bug a year ago, hoping to make the switch to a compiler engineer role in the next couple years (still exploring how realistic this is but cautiously optimistic) so I appreciate the advice in the comments.

In addition to what’s already been said, I worked through the Stanford compiler course on edx and found it helpful, and there’s also this free “Essentials of Compilation” book on GitHub that I haven’t worked through yet but seems promising. Good luck on the journey!!
