About Play Anything
Play Anything is a music AI lab dedicated to breaking down barriers to music learning, enabling anyone to play the songs that they love.
Our first product, Songscription, is the AI-powered "Shazam for sheet music" that turns any audio into sheet music, MIDI, or tabs in minutes. Our second product, Anything Piano, is an app that teaches you how to play any song on piano. Across our products, we've helped hundreds of thousands of musicians play, learn, and share their favorite songs.
We've raised a $5M seed led by Reach Capital and been covered in TechCrunch, Billboard, and MusicRadar. We're currently a small team, but we're moving fast to become a household name in music education.
Role description
Play Anything is hiring a Founding Mobile App Developer to help shape the next generation of tools for music learning. You'll lead the development of our mobile experience from the ground up, bringing our music transcription and learning products to mobile with a new AI-native learning app that leverages our proprietary models to enable users to learn any song, without the limitations of a static catalog.
This role is ideal for a seasoned full-stack mobile developer who wants to merge exceptional engineering skills with a love of music. You'll work closely with our engineering, design, and product teams to showcase our cutting-edge AI technology and bring a beautifully crafted, intuitive music learning experience to life. You'll join an early-stage team where the product changes quickly based on user feedback as we iterate toward product-market fit, and where your input will directly shape what we build.
Key responsibilities
- Lead mobile app development from zero to one, owning the entire codebase for iOS and Android
- Architect and implement core infrastructure spanning database architecture, authentication, and payments
- Ship fast and iterate relentlessly, translating product specs and design mocks into production code at exceptional speed, prototyping new features and refining them based on user feedback and usage data
- As the team grows, guide junior developers and help establish Play Anything's engineering culture and best practices

- Deep technical knowledge and problem-solving ability. You're the kind of engineer who can teach the team new approaches, anticipate issues before they arise, and make smart tradeoffs between speed and architecture
- Strong product intuition and collaboration skills. You work fluidly with product and design teams, push back constructively when needed, and have an eye for what makes mobile experiences delightful
- Able to work in-person at our San Francisco Bay Area office
- Experience playing an instrument and/or strong passion for music
