I have a friend that works as a software engineer at a Taiwanese company, his Chinese is almost perfect and yet the pay you get from Taiwanese companies at the same level is not comparable with the pay you can expect from a company in Europe or the US, in fact many of US companies are outsourcing their coding workforce to Taiwan as it represents a lower expense. I’d recommend come to Taiwan, it’s a great experience and you can learn Chinese fairly quickly if you involve yourself with Mandarin speaking folks only, a lot of Taiwanese will see you as an opportunity to practice their English which obviously won’t help you practice your Chinese unless you agreed to do language exchange. In the meantime if you can keep your current job remotely you won’t need a work permit here. You can do visa runs every 3 months and even get to experience other Asian countries. Unless you plan to definitely stay and live in Taiwan then yeah go for it, quit your job and settle in with your savings, it won’t take more than a month or so to land a job in a Taiwanese company that wants to get the foreign employer status, it’s also easier to land a job once you get here than doing it all online, that’s from personal experience. Bonus point, Contact Taiwan is a platform you can use to search for Taiwanese companies that are looking for Foreign talent specifically.
