You require a company registered in Thailand to offer you employment. You can apply for this visa outside Thailand and will be issued with a single entry non immigrant B (unless you already have a work permit, in this case you can receive a multi entry 1 year non B).
If you intend to work in Thailand and are not married to a Thai national you will need to be on this class of visa.
