JOIN YOUSICIAN

Yousician impacts and enriches the lives of millions of people by empowering them to play music they love, learn something new and nourish their well‑being. We merge music and tech to amplify the everyday. We reimagine the way people learn to play so that everyone can play.

And you don’t need to be a musician to join Yousician!

We’re a band of passionate professionals who love what they do, are great at it, and move to the beat of the same drum. We’re for all players: from newbies to seasoned pros. If you are looking for a rewarding career opportunity that helps shape the future of music‑tech you’re in the right place!

WHY YOU SHOULD APPLY

We’re looking for Web App Developers to help us raise the standard for mobile. In this role you’ll create mobile‑first web apps that feel as smooth, fast and engaging as native apps. 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 YOULL 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 VCs 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.
