Job description

You write solid backend code and you play an instrument. Now combine the two.

A seed-stage AI startup in San Francisco helps people learn the music they love. Upload any song and its own AI transcribes it in minutes, into notation, guitar tabs, MIDI or a playable piano view. Hundreds of thousands of people use it every month, and it's growing around 30% a month, entirely organically. The team is small and fast, and they're music people building for music people.

What you'll own

• The backend and infra behind a busy, fast-growing web app
• Keeping it stable and fast: bug fixes and improvements from your first weeks
• Growing into product work after a few months, side by side with the product engineer
• Code you write and reason through yourself, using AI tools as help rather than a replacement

Must-haves

• A real passion for music: you play an instrument and read music. A music project you built, at a hackathon or for fun, is a big plus.
• Full-stack, with your strength on the backend (front-end-only profiles won't fit)
• 2+ years of industry experience after graduating
• You think through problems yourself instead of handing all the thinking to AI
• Working from the San Francisco office, 9-9-5 (relocation is fine)

Bonus points

• Experience at a consumer, music, audio or learning-app company
• A backend system you ran in production at real scale
• A hard production problem you diagnosed and solved yourself

What's in it for you

• $150k–$200k base
• Work that connects directly to your passion
• Full insurance (medical, dental, vision, life), vacation, a gym at the office, and meals provided
• Visa sponsorship available

Good to know

• Full-time, on-site in San Francisco, 9-9-5
• You'll share product ownership with a teammate; this isn't a role where you set the product vision alone
• Process: intro call with the CTO - technical round (take-home or live) - on-site - offer
