Backend Developer (C# / .NET & Integrations) – Global Customized Solutions

Build the integrations that make complex access solutions work.

What happens when a customer needs SKIDATA products to work with a system they already rely on? That’s where you come in.

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 solve varied technical challenges, work with integration partners and turn specific customer requirements into working solutions.

Why this role matters

Access solutions need to work seamlessly with the wider systems customers depend on. Your work will help turn specific customer requirements into reliable solutions, extending the flexibility and reach of SKIDATA products across different markets and real-world environments.

The role

You’ll take ownership of your own projects, from design and implementation through testing and documentation, while working as part of the global 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.
• Work with APIs and interfaces — develop and integrate solutions using technologies such as REST, SOAP, gRPC, RMQ and socket-based communication.
• Support integration partners — provide integration support for public interfaces and help third-party companies connect with SKIDATA systems.
• 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.

What will help you succeed

• 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 Dev Ops, an understanding of secure coding, and familiarity with AI-assisted development tools.
  Collaborative approach — self‑organised, analytical and comfortable working with colleagues across different regions and cultures.
• 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.

Nice to have: Experience with Java, Spring Boot, Angular, React or other web technologies would be an advantage, but is not mandatory.

Why SKIDATA

At SKIDATA, you’ll work on technology that connects access solutions with the wider systems customers rely on, while having the autonomy to own your work and collaborate with colleagues across borders.
