Job Description
Who we are
Most people dream of being able to play a musical instrument. We develop outstanding products that enable anyone to achieve this dream. Our first product is flowkey: a revolutionary app for learning to play the piano. After our launch in 2015 flowkey quickly became one of the global leaders in its category, with more than 5 million users from over 100 countries. We are also one of the exceptions in the startup world, as we have been profitable from the beginning. This enabled us to go our own way and create a great culture.
Why join us
We believe that the best companies will help you live your life the way you want and become the person you want to be. Here is how we strive to do that:
- Flexible working hours: We only schedule a few fixed meetings every week—you're free to arrange the rest of your time in the way that best suits you.
- Remote work—and a beautiful office: We’ve found that it makes a difference whether we see each other in person or through a screen. That’s why we’ve put much love into designing our beautiful and spacious office in Berlin. At the same time, we deeply value freedom so we’ve set up our collaboration in a way that enables us to work from anywhere.
- Shared success: We distribute part of the company's annual profits among the whole team, on top of a competitive salary. This way everyone shares in our continuous business growth.
- Support for your growth: If you want to learn a new language, attend a conference, or pursue other self-development goals, we'll cover the costs—up to €2,500 per year.
- Love of music and a piano for your home: Whatever style of music you enjoy, you’re sure to find like-minded people among us. And you’ll get your own piano to play at home.

Changing the way people learn instruments
Almost everyone dreams of playing an instrument, but only a small percentage of people end up making that dream come true. What’s in their way? A lack of time, money, and belief that they can do it. We’re creating a new standard for learning a musical instrument. One that's fundamentally easier, more affordable, and much more fun – making it possible for anyone to realize their dreams.
Our first product is flowkey: a revolutionary app for learning to play the piano. We launched flowkey in 2015 and it quickly became one of the global leaders in its category. Today, over 5 million users from more than 100 countries have learned piano with flowkey. We're also among a small handful of startups that were profitable right from the start, enabling us to go our own way and create a great culture.

A culture that supports your freedom and growth
We believe that the best companies help you live your life the way you want and become the person you want to be. That's why we've created a culture that supports your personal freedom and growth by focusing on three main cornerstones:
• Freedom & responsibility
We all have unique life circumstances, needs, and preferences. That's why you're free to work wherever you want and whenever you're most productive. At the same time, we recognize that with freedom comes responsibility towards ourselves. It takes self-awareness and strength to take responsibility for your own development.
• Inner drive for growth
As we give a lot of freedom, we rely on the intrinsic motivation of our people to do the best work they can and grow both personally and professionally. The people we attract seek critical feedback, are open to other perspectives and see challenges as an opportunity for growth. We further promote growth by giving you a yearly budget of up to €2,500 for personal and professional development.
• Shared success
We want everyone at flowkey to have a share in the growing financial success of our business. One way we do this is by distributing part of the company's profits to the whole team.
