• When necessary, you will also contribute to the frontend using TypeScript and React, focusing your efforts where they create the most impact.

• You will assist with data migrations, refactorings, and technical modernizations, maintaining a strong emphasis on stability, maintainability, and quality.

⛳️ Requirements

• You possess extensive experience in software development and have a solid understanding of how to build, operate, and evolve modern web applications reliably.

• You work independently, proactively, and uphold high standards for quality.

• You have experience structuring technical topics, preparing decisions, and driving projects forward autonomously.

• You communicate clearly, reliably, and on equal terms with others.

• You are fluent in German and have a good command of English.
