According to VentureBeat, high mobile penetration, geographic closeness to China and India, horizontal platforms, strong social impact, and a rich culture are just some of the reasons devs are choosing SE Asia.
The bottom line is this: With tech careers, it never hurts to think outside the box. You won’t necessarily gain the most interesting work experience or make the most concrete social impact working out of an office in Mountain View. So next time you’re on the job hunt, cast a wider net — maybe wide enough to reach Thailand, Indonesia, or Singapore. You won’t regret it.
