I found a good extremely appropriate post doc in Switzerland, which was completely serendipitous. After I was done in Switzerland, I emailed some manager at Microsoft China out of the blue, and have been in Beijing ever since.

If you have specialized skills, you should be able to find demand for them anywhere. You probably can't start a career here with nothing special in your resume, but you can work for a big corp (e.g. Microsoft) and eventually get transferred to one of their overseas R&D offices. They generally value experience, which might not be something they can get locally.
