Mobile App Engineer (React Native)

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 Be Doing Joining us as an early-stage Mobile Software Developer, you are going to own a massive piece of the app's architecture and user experience. You will build our mobile technical foundation from scratch, making the core decisions on everything from API integration and performance monitoring to UI architecture and state management. Own the product beyond the interface: You will have end-to-end ownership over your feature releases. This means building smooth user journeys, managing complex local state, and ensuring the app delivers native-like, top-tier performance. Expect to write the code, ship it, and continuously iterate on what you've built. Design smart, scalable systems: You will lay out a robust mobile foundation relying on modern patterns such as MVVM or TCA. A major part of this is seamlessly connecting the client with our Effect-based backend and AI systems. You'll tackle tough engineering challenges, specifically focusing on streaming AI responses, real-time synchronization, and offline-first logic. Keep the technical bar high: You will actively hunt down and fix performance issues before they become problems, focusing on metrics like slow render cycles and app startup time. At the same time, you'll be responsible for leveling up the codebase's overall maintainability, type safety, and UX consistency. 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 Benefits Benefits Competitive salary package with equity component Fully covered Deutschlandticket BusinessBike (bike or e-bike via leasing, also for private use ) Working in a small but driven team built around performance and learning Flexible environment with high degree of autonomy Frequent team events and acemate parties! 🥳 Find more English Speaking Jobs in Germany on Arbeitnow
