This is fantastic! You really put a lot of hard work into researching and centralizing all of this, and I think it will be a great resource for the group. I never realized there were so many KR job web sites in English that were for non-teaching jobs.
Here's a few additional web sites that might interest everyone. For myself, I have not found them that useful, but others having diff career objectives might find the jobs/info more relevant to their needs:
5. Exec recruiters - if people are looking for exec search firms handling more senior positions, there are a couple very good ones who are KBC members (e.g., Halcyon and You & Company), but you can also find others -- serving various levels of professionals and industries -- through the Korea-related LinkedIn groups. Note: If your companies are looking to source for good candidates, working with a company such as Halcyon, Y&C, or other search firms might be an option to consider.
Attached is a list of new LinkedIn groups I received by e-mail this morning. Have not had a chance to evaluate them yet, so I cannot comment on them. Groups not listed under a specific geographic category should be presumed to be US-focused. Be careful when using groups that boast "60,000 users" as I have found in one case previously that it was linked to a for-profit company that turned around and was spamming me, even after I'd quit LinkedIn (still have not been able to get rid of them after two weeks).
I set up a site last year, targeting companies who are looking to hire "foreigners" (I don't like that term, but it's prevalent) in South Korea. There are a plethora of sites advertising teaching jobs, but positions in other industries are generally scattered around and difficult to find.
