The Nuclear Energy Agency (NEA)

The Nuclear Energy Agency (NEA) is an intergovernmental agency which operates under the framework of the Organisation for Economic Cooperation and Development (OECD). It facilitates co-operation among countries with advanced nuclear technology infrastructures to seek excellence in nuclear safety, technology, science, related environmental and economic matters and law. The mission of the NEA is to assist its 34 member countries in maintaining and further developing, through international cooperation, the scientific, technological and legal bases required for a safe, environmentally sound and economical use of nuclear energy for peaceful purposes. It strives to provide authoritative assessments and to forge common understandings on key issues as input to government decisions on nuclear technology policies.

The Data Bank operates as an international centre of reference for its member countries with respect to basic nuclear tools, such as computer codes and nuclear data, used for the analysis and prediction of phenomena in the nuclear field. It provides a direct service to its users by acquiring, developing, improving and validating these tools and making them available as requested.

We are looking for a skilled Software Engineer to develop and deploy a modern database and software infrastructure for the NEA Data Bank’s services, particularly its Computer Program Service (CPS) which is responsible for the secure and accountable acquisition, testing and distribution of nuclear simulation codes. The selected candidate will have strong DevOps, programming and data management skills and will work with Data Bank staff to develop robust, maintainable, production-quality software intended for long-term use, deployment, and support. S/he will work under the supervision of the Head of the Data Bank.
