Working Student Software Engineer (Flutter) (m/f/d)

Maple Tales builds reading and language-learning apps that real schools use every day. A Flutter-based reading app for elementary students, a teacher dashboard, and a white-label language-learning platform running under several school brands. We're a small team, so this isn't a shadowing role: you'll ship real fixes and features into production apps, work directly with the founders, and see your work reach classrooms within days, not sprints.

TASKS

• Ship features and fixes across our Flutter apps, including our student reading app, language-learning app, and teacher dashboard, on both mobile and web.
• Maintain and extend our white-label language-learning codebase that powers several branded language schools.
• Work directly with Firebase, from Firestore data and Authentication flows to Hosting deploys and Remote Config.
• Help us build a real CI/CD deployment pipeline. We already lint and test in GitLab CI. Deployment is still manual today, and we want you to help us change that.
• Test across browsers, devices, and branded instances to catch inconsistencies before our schools do.
• Review code, pair with the team on harder bugs, and contribute to technical decisions.
• Help us understand how students actually use Maple Tales. Instrument new features, analyze user journeys, and turn what we learn into product improvements.
• Prototype new reading and language-learning experiences and help turn the promising ones into production features.
• Improve our automated testing and monitoring so we catch regressions before our students and schools do.
• Build reusable components and internal tooling that make it faster to ship features across our apps and white-label brands.

REQUIREMENTS

• Enrolled student in Computer Science (Informatik), Business Informatics (Wirtschaftsinformatik), or a related field, available for roughly 20 hours per week during the semester.
• Based in Germany and legally eligible to work in Germany as a working student. Ideally, you are based in Frankfurt am Main or the surrounding area.
• Solid hands-on experience with Flutter and Dart, or strong cross-platform mobile development experience and the motivation to get fluent quickly.
• Familiar with state management patterns. We use BLoC, but experience with comparable approaches is absolutely fine.
• Experience with Firebase, or a transferable background with another BaaS or cloud platform, particularly authentication, document databases, and hosting.
• Enough web fundamentals, including HTML, CSS, and the DOM, to debug how Flutter Web actually renders. It has its own quirks.
• Comfortable with Git and collaborative development workflows. Experience with GitLab is a plus.
• Comfortable taking ownership of a problem, asking the right questions, and figuring things out without needing every step predefined.
• You know how to debug systematically and chase root causes rather than just symptoms. When something is "flaky," you want to understand why before you fix it.
• Fluent in English and comfortable working in an English-speaking team. German skills are a plus.
