I guess if we're just spitballing character ideas. One idea I was drifting toward was doing an AI, possibly doing some pretty morally black shit. Something like human trafficking. The reason is because the character is paid in some kind of rare and/or expensive medicine, that keeps a child alive. (Which happens to be someone I look after/close relationship with.) 

It's quite different from the other stated professions, but pretty sure AI/smuggling fit fine within the world. I think it would be an interesting anyway. ;P
