Have you Considered Asia?
CN, VN or Singapore perhaps?
China is a marmite choice. You'll love it or hate it. You don't find many western engineers working there, or even people like me who have spent a lot of time working there without living there (I lived in HK). There are quite a few East Europeans working in MNCs, though, who seem content with their situation. Maybe less so recently, with China's less welcoming attitude to high skilled foreigners.
Vietnam is limiting. There is a lot of assembly activity there now, assembling kits from Shenzhen, Japan, Korea and elsewhere. All the interesting stuff is done outside Vietnam. There is still a very limited amount of serious local engineering, despite the country having a pretty well educated workforce. Also, over the last 40 years the government keeps changing direction, with a huge impact on foreign people and businesses.
Singapore went from a great place for an engineer, to a terrible place as jobs moved to China, to a more stable place now. The government pumped a lot of money into R&D, distorting things, and maybe making them look better than a sustainable position in engineering might be. Nice place to live, though. Lots of foreigners who have spent years in Asia renting a home, seem to buy soon after they start working in Singapore.
Hong Kong was once a great choice, but makes no sense for an engineer today.
India has so many educated locals, its rare to see a foreigner working there, unless they are part of the management team of an MNC.
Thailand has had its appeal, but I haven't met any foreign engineers working there for a long time.
Korea seems to pull in quite a few western academics, but I don't see foreign engineers there beyond a few Chinese.
Japan is interesting. I've known western engineers working there, but more because they married a local woman, and settled with her, than direct career opportunities. Lots of people love the place. If you can't read and write, forget it.
