Description & Requirements

Your Team

The Register of Damage for Ukraine, established in May 2023 through an Enlarged Partial Agreement of the Council of Europe, is based in The Hague, Netherlands, with an office in Kyiv, Ukraine. It serves as a documentary record of claims and evidence on damage, loss or injury caused by the Russian Federation’s internationally wrongful acts in or against Ukraine. The Register receives claims from individuals, businesses and state and municipal entities in Ukraine regarding damage, loss or injury that they have suffered because of the Russian aggression in Ukraine.

It is also responsible for data management and information security. You will be based in The Hague.

Your Role

As a Senior IT Developer, you will:

design, develop, test, and maintain secure and high-performance ASP.NET Core 8.0 LTS application components and RESTful APIs, integrating with MongoDB (NoSQL) and Azure Storage to form the backend foundation of RCMS;

contribute to CI/CD pipelines within Azure DevOps, supporting continuous integration, automated testing, and reliable deployment processes;
containerise and deploy application components using Docker, ensuring consistency and portability across development, staging, and production environments;
troubleshoot, optimise, and monitor system performance across backend, frontend, and database layers to ensure reliability, scalability, and maintainability;
collaborate with cross-functional colleagues and external DevOps teams to ensure the secure configuration of Azure resources and the overall quality, security, and usability of delivered features;
document code, application logic, APIs, and deployment processes to ensure maintainability, traceability, and effective knowledge transfer;
participate in continuous improvement initiatives, contributing technical insight to enhance RCMS functionality, performance, and security.
