WHY YOU SHOULD APPLY

We’re looking for Web App Developers to help us raise the standard for mobile web. In this role, you’ll create mobile-first web apps that feel as smooth, fast, and engaging. Web apps that people love to use on their phones, not just a fallback for a native app.

You’ll have the chance to push the boundaries of web technology, build resilient apps that perform even in less-than-ideal network conditions, on many types of phones, and help millions of users learn and play music in a way that feels intuitive, inspiring, and joyful.

WHAT YOU’LL DO

• Build mobile-first web apps that deliver native-quality experiences in the browser.
• Ensure performance across a wide range of devices and network conditions.
• Collaborate closely with designers, product managers, and data scientists to shape features for mobile-first user experiences.
• Create and maintain reusable, accessible components optimized for touch gestures and mobile use.
• Improve tooling, testing, and performance from caching strategies to load-time optimization.
• Contribute to a high-quality culture through automated testing and knowledge sharing.

WHO YOU ARE

• Strong experience in modern web development (JavaScript/TypeScript, React, NextJS or similar frameworks).
• A track record of building responsive, high-performance web apps across devices and browsers.
• Solid understanding of mobile-first design principles, caching, and runtime performance optimization.
  Familiarity with automated testing (unit, integration, end-to-end).
• Collaborative, curious, and passionate about raising the bar for mobile web.
• Experience with Progressive Web Apps (PWAs) or hybrid development.
• Knowledge of accessibility standards and inclusive design.

WHAT WE OFFER

• You’ll have an opportunity to join our international team, backed by the top VC’s and competing with the best education applications in the world
• You’ll have a meaningful and profound impact on the lives of millions of musicians and future musicians all around the world.
• You’ll get to work with a passionate and friendly growing band of PMs, designers, developers and data scientists.
• You’ll get a competitive compensation package – salary, perks- and work in an awesome office in the heart of Berlin.
