I would recommend that you look into jobs from the Big Three in China (Tencent, Alibaba, Baidu, in that particular order).

All of them hire many people who do not hold a Chinese passport, so they have mature system in place to handle some of the issues you may be concerned about (visa, healthcare, etc). The culture in those companies would also be more international than most Chinese companies of course.

You could also look into YC companies based in China. I saw a job posting on HN a few days ago from a Shanghai-based YC company (I cannot remember the name at this point).

Good luck! :-)
