Your role in the team
- You work with the client’s subject matter experts to clarify which processes the application should support. You translate business rules and edge cases into a robust software design.
- You help decide how an application is structured, how its components work together, and where it connects to existing systems. You implement your decisions directly in the code.
- Depending on the project, you’ll develop business logic and interfaces using C# and .NET or TypeScript and Node.js. You’ll work on web applications as well as native apps for mobile devices and desktop.
- You design relational data models that clearly represent business relationships. When a query slows down as the volume of data grows, you investigate the root cause.
- You find ways to integrate new requirements cleanly into an established codebase. In code reviews, you share your experience and make technical decisions transparent to the team.
Our expectations of you
Education
- You have a completed degree in computer science, information technology, or a comparable qualification.
Qualifications
- You’re open to modern development tools and agentic coding. You’re keen to use coding agents strategically and review their suggestions to the same standards as your own code.
- You can explain technical decisions clearly to the team and to customers.
- You communicate confidently in German and English.
Experience
- You have at least five years of experience in professional software development. We particularly value experience developing custom software for clients or working on complex business applications.
- Your technical focus is on C# and .NET or TypeScript and Node.js. You have solid hands-on experience with one of these stacks and have already worked with the other.
- Knowledge of Vue.js, React, or Angular is also welcome, as is experience with native mobile or desktop applications. Java skills are an additional plus.
- You have experience in software architecture, apply clean code principles, and can explain when a design pattern provides a simpler solution to a specific problem.
- You have a solid understanding of relational databases and hands-on experience with at least one of the following systems: PostgreSQL, Microsoft SQL Server, Oracle, or IBM DB2.
