Fluency in TypeScript and experience with a modern frontend framework (Angular, React, or similar)

Confident in database modeling and comfortable working with cloud platforms (we run on AWS, but any cloud experience is valuable)

A doer mentality and high self-leadership: you ship, learn, and iterate quickly

Bonus: passion for music, audio tech, or creative tools

Own fullstack systems end-to-end: architecture, implementation, deployment, monitoring, and iteration

Collaborate with design, mobile, and music teams to turn creative ideas into intuitive, performant features

Help shape our architecture, engineering culture, and technical strategy as we scale from thousands to millions of creators

Balance reliability, performance, and security with the ability to ship quickly and learn fast
