He works for a medium size Canadian high-tech company. They provide software to large telecommunications firms. Because they work primarily with clients in SE Asia they have a couple of people posted here. I don't know that the Western software industry frequently sends people here, but you could look at firms which have clients here. The big ones like Microsoft, IBM, etc. have offices here but I'd think they try to hire locally first. Also, I think the only way you'll get a firm to send you here is after you put some time in with them. My BF has been with that company for 5 years.
You could look into the hospitality industry...hotel management or something like that. I've seen some opportunities for foreigners in that industry.
I'm in marketing and have had absolutely no luck in finding work in my field here...so that's something to avoid ;)
Good luck!
