Are there any Spanish teaching jobs available in Thailand?

When you take into account the number of Thai students studying Spanish compared to the number studying English, it’s pretty much as you would expect - a mere drop in the ocean. Some of the better Thai universities will employ teachers for their Spanish courses. There are probably one or two private language schools that specialize in Spanish and you might even pick up the odd corporate gig, where a company wants to give one of their executives some conversational Spanish ability; however, it’s generally slim pickings in Thailand for a teacher of Spanish.

Your biggest worry - certainly if you failed to land a full-time university position - would be getting enough teaching hours to make a living. You would be very fortunate to make ends meet on corporate and language school bits and pieces. I see this situation a lot with what I call ‘teachers of minority languages’, especially among French teachers. There always seems to be a lot of French teachers chasing too little work here. And that’s been the case for as long as I can remember.
