Where you come in

As a Software Engineer in flowkey’s Product-Led Growth team, you will work alongside our world-class engineering and other cross-functional product teams on a diverse, modern tech stack. Together, we will work to solve our new users’ most pressing needs across a range of codebases and technologies spanning from web, to server, to mobile. Every new user of flowkey will benefit from your work as they join the millions of users from around the world who have already begun to play the music they love.

In daily collaboration with the cross-functional Product-Led Growth team, you will work on the full TypeScript stack to optimize onboarding, messaging, subscription journeys and other touchpoints that drive user activation, engagement, and conversion. One week you may be implementing UI improvements for an A/B test in React Native, the next you may be working with our subscription database via GraphQL, on our content management tools in React, or improving high-performance edge compute infrastructure for our website.

You will thrive in this role if you love self-directed autonomous work in a tightknit team. Your experience with modern web and server technologies and a keen eye for rendering and load-time performance will be crucial to deliver innovations that captivate our users and drive business growth.

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.
