Its not green card permit but work permit which am talking about - Its for those who are legally already in the state. See below on INIS website but its a bit confusing as there is no mention about salary level it just says will be determined by DJEI

Applying for an Employment Permit whilst already lawfully resident in the State
Non-EEA nationals who are already lawfully resident in the State and hold a valid Certificate of Registration (GNIB card) with Stamps 1, 1A, 2, 2A and 3 immigration permissions, if offered employment in a recognised highly skilled shortage occupation (listed at
www.djei.ie), may apply to the Department of Jobs, Enterprise and Innovation for an Employment Permit. The assessment of skills, labour market shortages and appropriateness of the salary level will be determined by that Department.
