This is generalisations and doesn't work as all autistic people are different, but I'll give some tips anyway. Let them do what they are good at and gives them motivation. Ask for their opinion, and you will likely get a straight answer. If it's a highly ambitious and motivated person you need to protect them from over-working. Protect them from internal politics and bullying. Also be a good example for social interactions and culture because they will do like you do, so better be nice and smile.
