Remote Status: Hybrid

🚀 Role Summary

• Develop modern, functional, and intuitive user interfaces for applications using Java, Eclipse RCP, and SWT.

• Translate complex business requirements into robust, user-friendly technical solutions within a structured development environment.

• Collaborate closely with cross-functional teams, including product management and business stakeholders, to define and implement UI features.

• Analyze and resolve bugs, continuously improving the usability, stability, and maintainability of software components.

• Participate actively in code reviews, testing, and adherence to development standards and best practices to ensure high-quality software delivery.

📝 Enhancement Note: While the title is "UI-Entwickler," the responsibilities and required skills indicate a strong focus on Rich-Client Application Development using Java and Eclipse RCP, with a forward-looking inclusion of Web-UI technologies.
