I can't speak specifically to what jobs are available. What I can speak to is learning g-code and solidworks.
You get both of those, you can write your own ticket.
I know rudimentary g-code, the basic speeds and feeds, but I did a weeks class and can usually modify programs(I am a front-end programmer in one of my hats) to not break tools on cincom cnc lathes.
I also know some basic solidworks. The ability to create an STL file in solidworks and translate it into a runnable g-code program will get you in the door just about anywhere. The fact that you can spit it out an STL means that any company doing additive printing will also want you.
Create part in solid works
Print STL on 3d printer
Translate to a machined part on a CNC
Learning how to run a basic milling machine can get you extra side work as well. People always need something made and if you can do it with precision, it can be a reasonable source of income. If I had space, I'd have a milling machine.
