Senior Backend Developer (m/f/d) – AI-Driven Development

Area of Responsibility

Do you love good code, think outside the box, and want to help shape modern software development?

Then you are exactly right with us! We are looking for an experienced backend developer who not only develops high-performance applications but also wants to incorporate new technologies and AI coding tools into everyday development.

With us, you will work with modern technologies, have the freedom for your own ideas, and can actively participate in deciding how we develop software – from the initial idea to the finished solution.

Your Tasks

• Develop & Design: You will develop modern, scalable backend applications, APIs, and interfaces and accompany your solutions until they go into productive use.
• Use AI Meaningfully: You will use tools like GitHub Copilot, Claude Code, or Codex to make development processes more efficient and are keen to try out new possibilities.
• Shape Architecture: You will contribute your experience to technical decisions and further develop our software architecture and development standards together with the team.
• Ensure Quality: You will pay attention to clean, maintainable code, automated tests, and secure applications.
• Create Solutions Together: You will work closely with other developers, product managers, and our business departments and actively contribute your ideas.

Skills

• Several Years of Professional Experience in backend development and a good understanding of software architecture, APIs, and databases.
• Very good knowledge in at least one backend technology, e.g., Python, Java, C#, TypeScript, or Node.js.
• Experience with Git, CI/CD, as well as modern development and testing methods.
• Interest in AI-supported software development – ideally, you have already worked with GitHub Copilot, Claude Code, Codex, or similar tools.
• You work independently, enjoy taking responsibility, and have fun developing solutions together in a team.
• Good knowledge of German and English for technical collaboration.

You don't meet every point? No problem! If you have sound backend experience and are eager to develop further in the area of AI-supported development, we still want to get to know you.

What You Can Look Forward To

• Technical Design Freedom: Your ideas count! You can actively help shape architecture, technologies, and development processes.
• AI Instead of Stagnation: We use modern AI coding tools in our daily work and continuously develop our way of working.
• Exciting Projects: You can expect diverse internal and external projects with various technical challenges.
• Responsibility & Teamwork: You will be responsible for your topics and at the same time work with a team that shares knowledge and supports each other.
• Further Development: You will have the opportunity to try out new technologies, expand your knowledge, and develop professionally.
