ORGANIZATIONAL UNIT

The Radiocommunication Bureau (BR) is responsible for the application of the Radio Regulations and for technical and administrative support of ITU World and Regional Radiocommunication Conferences, Radiocommunication Assemblies and Study Groups. The Bureau also carries out the international regulatory processes for registration of frequency assignments and satellite orbits and assists administrations in their coordination and implementation of frequency spectrum and orbit requirements as well as in resolving cases of harmful interference. It provides the specialised technical secretariat for the work of the Radiocommunication Study Groups and the Radiocommunication Assembly in the development of recommendations for spectrum utilisation and radio system characteristics. The BR is organised into four Departments: Space Services Department, Terrestrial Services Department, Informatics, Administration and Publications Department and the Study Groups Department.

The Informatics, Administration and Publications Department (IAP) comprises of three Divisions: Space Applications Software (SAS), Terrestrial Applications Software (TAS) and Business Operations and Planning Division (BOP). The Department is responsible for the development and maintenance of software and related tools used by the BR as well as software adapted for national frequency management units, providing the necessary user support for the areas concerned. It carries out studies related to policies for the technologies to be used for the information and computational systems within the BR and with administrations in the fields of management of the radio frequency spectrum and the various satellite orbits. The Department is responsible for managing all aspects of the BR's operations, including the development of BR operational plans, organizational support of ITU-R conferences and meetings, BR project management processes and procedures, BR text editing and publications, as well as promotion and membership. The Department is also responsible for human resources management and planning for the BR.

DUTIES AND RESPONSIBILITIES

In the Space Applications Software Division (SAS) within the Informatics, Administration and Publications Department (IAP), under the supervision of a Senior Software Engineer, the duties to be performed are as follows:

• Develop and refine ReactJS-based web applications connecting to a robust C# .NET Core backend, gathering clear requirements, crafting functional specifications, and designing scalable application architectures, data models, and database configurations. Perform integration tests and oversee production deployments with detailed documentation.
• Intervene at the code level in both ReactJS code and backend services to troubleshoot and resolve issues in frontend modules, backend logic, or database operations. Write targeted tests to quickly isolate bugs and implement efficient fixes.
• Analyze client requirements to architect, code, test, and deploy new or enhanced web applications and modules using ReactJS. Refine coding tools, standards, and templates to streamline future development.
• Actively participate in projects or lead specific coding initiatives by identifying, developing, testing, and deploying updates and improvements to existing ReactJS components and backend systems.
• Collaborate closely with fellow web application developers and software engineers to assess ongoing development tasks and project proposals, ensuring high-quality code, optimal performance, and adherence to best practices across all systems.
• Consistently improve coding practices by reducing turnaround times, automating repetitive tasks, and streamlining workflows, while working collaboratively to deliver robust, high-quality ReactJS code integrated with a C# .NET Core backend.
• Keep current with the latest web development trends and ReactJS best practices, actively contributing to the refactoring of legacy codebases and migrating them to modern frameworks and efficient coding standards.
• Manage additional responsibilities such as maintaining comprehensive code and process documentation, providing user training on new web applications, and participating in technical seminars to further enhance development skills.
• Perform other related duties as assigned.
