Berlin
Full-time
Permanent employee

Your mission

Together with our team, you will develop and scale a modern investment app built on the latest technologies and architectural principles. You will implement sophisticated features in a 100% Jetpack Compose environment, powered by a robust MVI architecture and a consistent Unidirectional Data Flow approach. You will work within a highly modularized codebase, develop clean APIs for both backend integrations and our Design System, and actively help shape the technical direction of our product.

YOUR PROFILE

  • You have strong expertise in Kotlin and Jetpack Compose.

  • Coroutines and Flow are your standard tools for reactive programming.

  • You think in terms of MVI, State Management, and Unidirectional Data Flow. Clean state modeling is the foundation of stable software for you.

  • You have extensive experience working with modularized codebases and understand why a clear separation of features leads to scalable and maintainable applications.

  • You have a strong sense for UI and Design Systems and enjoy working closely with designers.

  • You leverage AI and agentic development workflows to automate repetitive tasks, accelerate development, and focus on solving complex problems.

  • Clean Architecture, maintainability, and a great developer experience are just as important to you as delivering new features.

WHAT SETS YOU APART

  • You are a team player who values code reviews and technical collaboration.

  • You understand the product—not just the code.

  • You know the difference between perfect code and pragmatic solutions that deliver value quickly.

  • You understand that not every problem can be solved with code, and you work closely with Product Managers and Designers to find the right balance between quality, complexity, and delivery speed.

WHAT WE OFFER

  • A modern Android stack: 100% Kotlin, 100% Jetpack Compose, MVI architecture

  • A highly modularized codebase

  • An experienced engineering team that shares knowledge and makes architectural decisions together
