The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) is an international organization that will be established upon the entry into force of the Comprehensive Nuclear-Test-Ban Treaty, a Convention that outlaws nuclear test explosions. Since the Treaty is not yet in force, the organization is called the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO).
It was founded in 1996, has over 260 staff from over 70 countries, and is based in Vienna. It is headed by the Executive Secretary, Lassina Zerbo from Burkina Faso. The CTBTO’s main tasks are the promotion of the Treaty and the build-up of the verification regime so that it is operational when the Treaty enters into force.
The CTBTO provides exciting employment opportunities in a rich diverse work environment for high calibre candidates with scientific and technical qualifications, as well as for those with management and non-technical skills. The Organization prioritizes and promotes the highest standards of professional competence, experience and integrity.
CTBTO is committed to diversity and inclusion within its workforce and encourages qualified female and male candidates from all national, religious and ethnic backgrounds, including persons living with disabilities, to apply to become a part of our Organization.
Employment Types and Conditions All staff members of the CTBTO are subject to the Staff Regulations and Rules which outline the fundamental conditions of service and basic rights, duties and obligations.
