If you have autism / AS, the greatest job in the world for you probably will have less to do with what it is and more to do with how you can do it. Will this job allow you some flexibility? Will you work with people who at the very least aren't hostile? Will you do something that interests you? Will the environment not drive you crazy?
I never thought I'd be doing what I'm doing. I thought I'd be doing something "more important" with my life. But I work for people who know me and like me anyway, and who are AS-friendly. I'm allowed to use earphones with white noise when things get too overwhelming in an auditory sort of way. I can walk around the building whenever I need to "reset" myself. And they know that in return I will be unflinchingly honest (not always a good thing, I've found), that I will work my a$$ off, and that I will do the best job I can do every day even when I'm frustrated. It's a good tradeoff.
I actually have a new job with this company. I used to have an assembly job. I loved it. Things were predictable; I knew exactly what to do next and how to do it. Whether or not the finished product was correct was a very objective thing. I could work with other people, or not, as I chose. And I got to work with my hands, often doing repetitive things, which I find calming. Now I have my "dream job." I'm a technical writer. I'm really struggling with it. I thought it would be great, and it's very hard. I have to work with people in new ways, I have less-defined projects and FAR less structure in my day at work. I have to manage myself differently, and this is hard. My executive function skills aren't good, and this is a problem.
I guess what I'm saying is that finding a job that you can do well and be happy in is far more important than what it is exactly. No group of strangers can tell you what that'll be.
