Hi, I read through all the comments and would like to offer my experience of getting my man a job in Taipei. (FYI: We met and got married in California at 2005, he visited Taiwan with me a few times and has fallen in love with Taiwan completely since. Then we decided to migrate to Taipei for a few years at 2008)
Your traveler visa does give you 90 days in Taiwan. We used to go travel HK, Korea and Japan when he is about to run out of his 90 days time. It's cheap to travel to these nearby countries, and fun btw. And by doing it about 3 times, he gained almost a year time duration to figure out a job he wants.)
He is also only a high school grad in US, and didn't care to continue higher education pursuits in our 30s. So he worked as an English teacher under the table for all that time (1 year) prior to finding his current job. He taught 1-3 graders English which was easy and fun to him as well.
He was a craft beer specialist in Calif. so he enventually found a brewery in Taiwan that hires him as draft system tech to help bars setup shops "correctly". The tap handles, draft lines, refrigerations.... I'm sure you are very familiar with. (As above comments have mentioned, craft beer market is growing fast in Taiwan in recent years.
He only speaks English. It was hard for him back then, but nowadays Taiwan is getting so international that most young people, the current generation, understand English to a pretty good extend. So it's getting so much easier for an English only person.
We live in Neihu, right next to the technology town and Miramar mall, which we meet lots of forengers daily. And yes, many of them work in tech town and only speak English. (But these are higher level jobs of course, thus having degrees are "almost" a must.)
I say almost, because Taiwanese companies do value your skills over your deploma for forengers are harder to come about. And you might just land yourself a legit job if you are good at what you do. Still, you gatta be completely honest to them on your education though, none of that fake deploma stuff.
Hope you find something great here.
And don't let negative comments clouded your judgements. If you try hard enough, you might just find what you are looking for.
I'm sure you know there will be difficulties and hardships lying ahead, but so as making it in anywhere else in the world. Still, follow your dreams and aim high. If all fails, at least you got to chase after your dream and you will gain so much in life anyways.
