• Ensuring code quality through code reviews, unit tests, and CI.
• Analysis and resolution of technical issues and performance optimization.

Requirements

• Degree in Computer Science or equivalent professional experience.
• Several years of experience in software development — ideally in financial or other complex projects.
• Strong knowledge of the Java Technology Stack and Kotlin; hands-on experience with modern frameworks and tools.
• Experience in building responsive web and mobile applications.
• Nice to have:
  • experience with component-based UI libraries,
  • cloud-native architectures,
  • reactive data infrastructure,
  • relational databases.
• Independence, analytical thinking, high quality standards, and ownership mindset.
• Proactiveness and entrepreneurial approach to product development.
• German language proficiency at min. B2 (mandatory).
• Polish language proficiency at min. B1.

We offer

• Remote work with the possibility of business trips to the client in Germany.
• Clear communication and a flat structure — fast decisions and real influence on the project.
• Long-term cooperation — min. 12 months, with a high probability of extension.
• A supportive team — openness, trust, and strong collaboration.
• Projects in the financial sector and other industries (e. g. , energy, education, manufacturing, logistics).
• International environment — cooperation with DACH-region teams and clients.
• Flexible form of employment — employment contract or B2B.
