Who we are:

For more than 70 years, NATO’s mission has been to preserve peace and security in the Alliance for nearly one billion citizens.

We are the NCI Agency, a team of 3000 civilian and military staff in 29 locations throughout Europe, North America and Asia.

Our technology and cyber experts allow NATO to conduct critical operations, protect NATO’s airspace, make data-driven decisions, defend against cyber-attacks, secure NATO networks and maintain superiority in space. This is all possible because of our greatest force, our people. In order to keep this edge we aim to hire, train and retain the very best staff.
