Some learnings to consider
1: Fit in a box. Accountants, teachers, nurses, doctors are easy jobs to travel with, once they understand how to get local accreditation. So for tech/engineering jobs it's good to have a very clear definition and track record of what you are and for that to be in demand. (Even better - have your own business and operate from anywhere, and/or study abroad)
2: Be in the right time and place. Cities and countries have a sweetspot for life stages, and also for political and economic cycles. I got to be in the UK doing the 90s, and US during the dot com boom, and Australia in a mining boom. Go where it is easy and fun.
3: Balance work and travel. Work hard, but enjoy the location while you are there. But if work is all consuming then take a lot of time between destinations to travel locally and internationally.
Come to New Zealand! We have a number of ways to get in. At one end is the working holiday visa (1), which is available to a few countries, costs NZ$420 to apply and gets up to 12m work. At the other end is the Active Investor Plus Visa (2) (Our fund is on the eligible list). And there are the usual options in-between (3).
