Who We Are

For over 70 years, NATO has worked to safeguard peace and security for almost one billion citizens. The NATO Communications and Information Agency (NCI Agency) delivers the technology that keeps the Alliance connected. Our people enable NATO to conduct operations, defend against cyber threats, protect its airspace, drive digital transformation and maintain technological advantage.

When you join us, you become part of a diverse community of civilian and military professionals across 29 locations, united by one mission: to strengthen the Alliance through world-class technology and innovation.

About The Job

Based in Braine l’Alleud, you will join the NATO Integrated Mission Services Centre (NIMSC). NIMSC provides NATO and its partners with scalable, protected and highly available operational services for NATO missions, operations, exercises and business continuity.

  • This is a temporary location pending completion of the new SHAPE facility at Camp Casteau in Mons. The Braine L’Alleud site is expected to close by end 2027, with future duty stations shifting to Brussels or Mons, depending on function and business needs.


As a CIS Security Officer, you will play a key role in protecting NIMSC systems, assessing risks, ensuring compliance with NATO security frameworks and supporting the accreditation and operational readiness of NIMSC capabilities. The role combines hands-on security work, governance and risk management, and close coordination with the NATO Cyber Security Centre.

What You Will Be Doing

You will contribute to a wide range of CIS security activities, including:

  • Conducting vulnerability assessments, security risk assessments and business impact analyses
  • Monitoring security operations, reviewing incidents, escalating issues and supporting investigations when required
  • Planning and coordinating security architecture development with the NATO Cyber Security Centre for large scale systems and networks
  • Assessing change, access and configuration requests from a CIS Security perspective to ensure compliance with NATO policies and standards
  • Producing and updating accreditation documentation, supporting security accreditation processes and liaising with accreditation authorities
  • Tracking CIS threats, advising on mitigation measures, and contributing to policy and security framework development
  • Supporting the enrolment of NIMSC systems into monitoring and incident response programmes, and maintaining the CIS Security Risk and Issue Register
  • Providing CIS security advice, training and awareness sessions to technical staff, project managers and service delivery teams
