Full-Stack Engineer – Music AI

**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

**When you apply, please include**

* Your CV (PDF), your **LinkedIn URL**, and GitHub or a link to something you built
* The instrument you play, and any music project you built
* A backend system you owned in production, and the scale it ran at
* Your current location, and confirmation that on-site San Francisco works for you
* Your visa or citizenship status, and if you'll need sponsorship
* Your base salary expectation, your notice period, and any other interview processes you're in
