About us
Most people dream of being able to play an instrument – and at flowkey, we’re dedicated to making that dream a reality. With our innovative app, we provide an easy and motivating way to learn to play the piano. Since our founding in 2014, flowkey has become one of the leading players in this field, helping millions of people worldwide discover the joy of piano playing.
What sets us apart is not just our product – it’s the journey we’ve taken together. Thanks to our early success and sustained profitability, we’ve been able to grow independently and foster a culture that truly reflects our values.

We believe different perspectives drive creativity and innovation, which is why we celebrate our differences and offer equal opportunities for everyone. Our goal is to create an inspiring environment where both personal and professional growth are not only possible but actively encouraged.

Where you come in
At flowkey, Core Technologies is the autonomous research and development team responsible for solving some of the company’s greatest technical and algorithmic challenges. Real-time polyphonic note detection and score following, recommendation and skill detection systems, and synchronizing video playback with sheet music are just some examples of the areas we work on. These technologies enable flowkey’s award-winning user experiences for millions of piano learners around the world.
As a Software Engineer on the team, you will work to flesh out and productionize elegant technical solutions alongside researchers, technical leadership, and other product teams, ensuring our Core Technologies are usable, performant, and bug free. Enabling your work is a uniquely diverse, modern tech stack and a great deal of freedom and responsibility.
You will thrive in this role if you love to think outside the box; to bend technologies to your will in order to solve novel challenges. You don’t always need a clearly documented path forward. Instead, you enjoy solving challenging problems from first principles in a clean, elegant, and understandable manner. You are happy to give and receive feedback to foster growth and common understanding across the team.
We want to share with you our passion for innovation, curiosity, and learning. We encourage all team members to focus on areas that interest and excite them the most, and actively foster self-responsibility, self-direction, experimentation and growth.
What you’ll bring
Essential:
- Degree in Computer Science or equivalent experience and accomplishments (understanding of fundamental data structures, memory management, and algorithms is a must).
- Above-average problem solving skills.
- Fundamental knowledge of Audio DSP and/or MIDI.
- Proficiency in Swift, C, or Rust, and an understanding of Python or TypeScript.
- Proven ability to profile, debug, and systematically improve computational and memory resource usage / performance.
- Willingness to learn by doing, think creatively, and work with unproven solutions and/or incomplete knowledge.
- Eagerness to learn through a feedback culture and share knowledge with the team.
Bonus points:
- Experience with node.js backend development: GraphQL, MongoDB, PostgreSQL
- Experience with frontend development: React, SwiftUI
Experience in any particular technology or process is far less important to us than the ability to learn quickly, turn ideas into solid code, and easily ramp up in new areas.
