App developer Jobs in Berlin

acemate is building an AI learning & teaching platform for higher and further education institutions. We have strong traction, secured funding and are entering an exciting growth phase. We're looking for a passionate Mobile App Developer (React Native) to drive our product forward and help us scale.

About acemate

Founded in 2024, acemate has quickly become the leading AI learning platform for higher and further education, trusted by top-tier institutions across four countries, including University of Cologne, WHU and the German Chambers of Commerce and Industry (IHKs).

• Our Mission: Democratizing access to personalized learning. We don’t believe that AI will replace educators. Instead, we empower them to design and deliver personalized learning experiences at scale.
• Our Growth: We've raised pre-seed funding and are growing rapidly. While we focus on higher and further education in the DACH area today, we're already expanding into new regions and markets.
• Our Culture: We’re a young, driven team passionate about tackling the toughest challenges in education. We embrace builder culture and minimize scheduled meetings for ad-hoc discussions and maximized focus on coding and creating.

Tasks

What You'll Do

As an early-stage Mobile Software Developer, you will have significant control over our app's user experience and architecture. You'll guide the mobile technical infrastructure from the ground up, directing everything from state management and UI architecture to performance monitoring and API integration.

• Drive the core product past just the UI: You'll be fully responsible for the features you release. That entails engineering fluid user journeys, handling complex local state, and guaranteeing high-quality, native-like performance. You'll code, deploy, and iterate on everything you ship.
• Build intelligent, scalable architectures: You'll structure scalable mobile setups using modern patterns like MVVM or TCA, ensuring tight integration with our AI systems and Effect-based backend. You will solve difficult engineering problems centered around offline-first logic, real-time synchronization, and streaming AI responses.
• Maintain high technical standards: You'll spot and resolve performance bottlenecks—such as app startup time and slow render cycles—proactively. Alongside that, you will improve UX consistency, type safety, and overall maintainability across the codebase.

Requirements

What We're Looking For

• Strong experience with TypeScript & React Native.
• End-to-End Ownership: You don’t throw things over the wall. You own your features until they are running successfully in production and used by real learners.
• Startup experience: You’re comfortable in fast-paced, evolving environments
• Balanced AI approach: You knew how to code before Cursor and Claude Code, but understand how to leverage them effectively
• Product passion: High identification with our mission to transform education
