About restricted roles
Restricted units build and protect our platform. Their roles are advertised by unit number, role family and level only, with no programme, customer or capability detail. Unit numbers are random and carry no meaning.
Before you start there is enhanced screening (identity, right to work, five years of verified history, references), an interview with the unit and a separate security interview. We say "restricted", not "cleared": Ireland has no statutory clearance for private-sector staff.
NATO grade equivalents follow STANAG 2116 and are indicative, to help people who have served read a role. They are not ranks.
