Postsecondary faculty are normally hired directly by institutions, departments, or faculties. Recruiting services are sometimes used for administrative staff positions. Since many postsecondary institutions overseas are publicly controlled and faculty sometimes have civil service status, hiring may be accomplished through national, state, or provincial agencies. Foreign faculty members often have special appointments pertaining to their temporary and non-citizen status, and such persons may not be legally considered part of the regular faculty.
For regular academic positions, you should contact institutions directly as well as keep up with overseas opportunities that may be posted through professional and disciplinary associations and their news outlets.
