TACA seems to have an online employment application website. It is pretty much disfunctional:

Other than that, as a Salvadoran you should apply at the TACA office in El Salvador.
The number for the administrative offices of TACA in San Salvador is +503-2667-8888. I don't know how it is in El Salvador specifically, but I find that in much of Central America, a company may be desperate for pilots but will make it fairly difficult for you to contact them by keeping contacts a mystery, including a cool reception or being totally unapproachable, etc. I think it is part of a misguided master/slave mentality. Treat them mean, keep them keen.
