Im sure this is mentioned in this thread but just to be sure make sure you check this out.
Only thing I ever applied to on there was a python job at a carbon capture startup in New Zealand. I got a call back. Didnt end up working out but 100% is a pretty good call back rate so far. Looking forward to getting back on there in a couple months.
Also if you haven't heard of / checked out Recurse Center it might be a good place to make your career transition. It's kind of why they exist.
PS Right on! Im thinking about the exact same career pivot myself. Very inspiring to see this :)
