Web App Developer (m/w/d)

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.

If you thrive on building performant web apps, shaping user experiences, and moving fast in a multidisciplinary team, this is your chance to make a global impact.

WHAT YOU'LL DO

• 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

• 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.
