In this role, you will take ownership of the mobile app end to end: the screens learners use, and the path that gets them there, code, package, and distribution to the App Store and Google Play. You will work in an agile, parallel engineering environment with Claude Code woven into your daily workflow. You will work cross-functionally with backend and platform teams (consuming typed API contracts and the mobile CI pipeline) while enjoying high autonomy and low bureaucratic friction. Best of all, you will work primarily on a greenfield app, building a modern, clean client with no legacy debt. Core Responsibilities * App Architecture: Design and build learner-facing features in React Native (Expo), from screens and navigation to state management, within a shared TypeScript layer also consumed by other client surfaces. * Core Tech Stack: Utilize React Native and TypeScript as your primary stack, building on Expo's managed workflow and the team's shared design-system package. * Mobile Delivery: Own the path from code to store: build configuration, versioning, code signing, and submission to the App Store and Google Play. * CI Integration: Trigger and consume the platform team's mobile CI/CD pipeline (EAS Build via GitHub Actions) to ship signed builds without owning the underlying infrastructure. * AI-Assisted Engineering: Actively integrate advanced tools like Claude Code into your daily GitHub and development workflow to maximize code quality and speed. * Clean Code Standards: Champion and apply best practices for type safety, testing, and accessibility across the app. ## Related Videos - [API Design - Getting Started](https://www.wearedevelopers.com/videos/33-api-design-getting-started) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [There's an app for that - on the role of cross platform development in the app development ecosystem](https://www.wearedevelopers.com/videos/278-there-s-an-app-for-that-on-the-role-of-cross-platform-development-in-the-app-development-ecosystem) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [Finding Jobs in Germany](https://www.wearedevelopers.com/magazine/375-finding-jobs-in-germany) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [How to Find Tech Jobs in Berlin](https://www.wearedevelopers.com/magazine/291-how-to-find-tech-jobs-in-berlin) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023)
