Software Engineer – Product - led Growth (m/f/d)

Software Engineer

At flowkey, the Product-Led Growth team is dedicated to crafting features that help new users fall in love with learning piano — from their very first interaction. We focus on removing friction and surfacing value early to guide millions of users toward their first 'aha' moments with flowkey. As a Software Engineer on this team, you'll work with a small, cross-functional team of engineers, designers, and product thinkers to create high-performing, joyful experiences that drive user activation, engagement, and conversion. Your work will center on helping new users get started, form habits, and become active subscribers. We work across platforms — iOS and Android (React Native) and web (React) — and validate ideas through A/B testing to ensure real impact.

In close collaboration with product, design, data, and copy, we aim to grow flowkey in ways that are both user-centered and sustainable. You'll thrive in this role if you enjoy self-directed work in a tight-knit team, have a strong grasp of modern web and backend technologies, and care deeply about performance and user experience. You bring curiosity, creativity, and a hands-on mindset — and you're motivated by solving meaningful problems in ways that benefit both our users and the business. We care about building a culture where curiosity and initiative are celebrated. Whether it's shipping a small experiment or exploring a big new idea, you'll have the freedom to pursue what excites you — and the support to turn it into something real.

Essential:

• Proven problem-solving and analytical skills
• Proficiency in TypeScript, HTML and CSS
• Proficiency in React and NextJS
• Familiarity with server-side TypeScript (node.js, express.js) and databases (preferably MongoDB)
• 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 one or more subscription services such as Apple AppStore, Google Play Stripe, Braintree or similar
• Experience with experimenting and A/B testing
• Proficiency in Swift, cloud services, and/or CI/CD/QA
• Experience with React Native, iOS, and/or Android development
• Passion for music
• Active interest in contributing to open source
