I'm interested in moving to Singapore, Hong Kong, or Taipei. I'm a software engineer. I'm European - only speak English and French. What are some international companies with development offices (not sales etc) in these cities where English is the operational language?
None. Hsinchu (near Taipei) has some hardware firms. China would be a better choice if you want to work in software.
Grab is in Singapore.
Google Taipei or Singapore to start and you can transfer after you get to know the area better
Singapore, no questions asked, just go
Fb, Amazon, Google and grab in Singapore.
FB doesn’t have a real development office in Singapore.
Maybe you can try Google Taipei.
MSFT Taipei
Unlikely English in Taiwan or HK, Singapore should be fine
