International school jobs

Hi,
I'm a qualified primary school teacher currently working in an international school in Bangkok.
Myself and my partner are very interested in relocating to Seoul.
There are a lot of international schools in Bangkok, and they seem to be almost constantly advertising jobs on the TES website.
I've been checking for Seoul jobs on TES and there are none.
I was wondering where the schools advertise, and when the jobs for the new school year come out?
In Thailand, the main recruiting season is from November, right through to April or later and pretty much all of the jobs are advertised through the TES website.
Any help, advice, thoughts would be appreciated.
Thanks,
Jacks

Really depends. Also turnover  this year will be lower I suspect, as Korea is  basically safe,  no real lockdowns and the economy  is holding up hence good job security. Moving is super risky!

Main reason why I see colleagues at my school say they are leaving this year is homesickness especially for elderly relatives, so they are looking for jobs at home.

Just keep looking. Jobs in Korea  are competitive in the best of times as pay is high so persistence is required.
