CAD jobs?

Hello! Quick question, have any of you come across jobs related to computer aided design?

I have long been interested in learning CAD as a skill and hobby, and I'm also going to be needing it in my university studies. I'm thinking it would be really cool if learning it brought me a few extra bucks.

Also, do any of you know of any useful online CAD courses I could take up? I'd be very greatful for any pointers. Thanks!
