Popis:

Here you contribute to something greater: creating the conditions for a safer society. Background - a project with real significance Carmenta has a long history of developing software for defense and critical systems. Today we are building a defense operations system for information processing and tactical analysis that functions as a central node in a network of systems where information is collected and shared from, for example, sensors, drones, and command systems. It enables creating a complete picture of the situation and supporting real-time decision-making. A central part of the solution is the ability to analyze and model what may happen in the future in several parallel scenarios. Development takes place close to reality and the solution is further developed in international collaborations, such as NATO exercises like CWIX, where systems are evaluated in realistic scenarios. About the role As a backend developer, you work with development in .NET at the intersection of data, analysis, and integration where information flows, integrations, and secure data handling are central. You become part of a self-organizing team that develops a modern and intelligent system in close collaboration with the Swedish Armed Forces. Here there is great opportunity to influence technical solutions and architecture in a system that plays a central role in information exchange between defense and security actors. Since the solution is under development and many parts are still being shaped, you get to drive how functionality and secure information handling should be designed. The role involves, in short, that you: Develop and further develop backend solutions in C#/.NET Work with integrations against other systems and standards Build and develop information models to handle and analyze data Implement solutions for secure communication and access Interpret and implement various communication and data formats Moving forward, together with your colleagues, you will build and further develop authentication and authorization in the system, with focus on identity, access, and secure communication.

You are curious, solution-oriented, and enjoy tackling problems where there isn't always a given answer and where everything isn't predefined.
