About the project

At Radiotech, we believe music should be accessible to everyone — not only to those who grew up taking lessons.

We are a product team inside the Gismart ecosystem, focused on building and growing music apps across iOS and Android. Our portfolio includes products with millions of installs, rich functionality, and a long history of product development. These are apps that help users not only consume music content, but also play, learn, practice, create, interact, and enjoy the process.

Our goal is to make music feel more approachable, engaging, and human for beginners, hobbyists, and people who want to bring more music into their daily lives.

We are looking for a Product Manager who will not wait for perfectly detailed instructions, but will proactively identify opportunities, take ownership, and move the product forward together with the team.

• Hands-on experience with iOS and/or Android app development processes

• Experience working with mobile product teams: engineers, designers, QA, analytics, marketing, and product leadership

• Strong analytical skills: funnel analysis, cohort analysis, retention analysis, A/B testing, and experiment interpretation

• Ability to work with ambiguity, define priorities, and move initiatives forward independently
