Backend Developer (C# / .NET & Integrations) – Global Customized Solutions As a Backend Developer, you'll primarily work with C# / .NET, designing and building software integrations that connect third-party systems with SKIDATA products. You'll take ownership of your own projects, from design and implementation through testing and documentation, while working as part of the general team. Alongside your development work, you'll support colleagues across regions and contribute to shared coding, architecture and engineering practices.

What You'll Work On Build custom integrations — design, develop, test and document backend solutions connecting third-party systems with SKIDATA products. Develop in C# / .NET — build reliable solutions primarily using .NET. Contribute to engineering practices — support the implementation of coding standards, architecture guidelines and reusable frameworks, and contribute to practices such as CI/CD and AI-assisted development.

Support colleagues across regions — assist regional developers and contribute to code reviews, knowledge sharing and consistent engineering quality. Backend development experience — strong professional software development experience, with solid hands-on skills in C# / .NET. Integration experience — hands-on experience building, deploying and supporting production integrations between systems with exposure to technologies such as REST APIs, SOAP,



RabbitMQ and socket-based communication.

Software development foundation — experience with databases and software design. Modern development practices — familiarity with CI/CD and DevOps, an understanding of secure coding, and familiarity with AI-assisted development tools. Language skills — Fluent Spanish is essential for day-to-day collaboration with the local team in Madrid.

Business-level English (at least B2) is required for working across the international organisation.

Experience with Java, Spring Boot, Angular, React or other web technologies would be an advantage, but is not mandatory. Innovation & scale — Work with modern backend technologies, APIs and integration solutions as part of a global organisation. Autonomy & trust — Take ownership of your projects from design through delivery, with the freedom to shape solutions and solve problems in your own way.

Growth & development — Broaden your technical experience through varied projects, different technologies and collaboration with colleagues across regions. Work–life balance — Benefit from a flexible hybrid working model that supports a sustainable way of working. Ready to build what connects it all?
