Overview

Back End Developer role at Setmixer

At Setmixer, we're bringing live recordings back. Our mission is to make sure no live show is ever lost. We capture the raw energy and talent of live performances in studio-quality audio - we call it a "setmix": a high-quality recording of a show, just as it happened - unpolished, intimate, and real.

We're reviving the beloved tradition of live recordings for the digital age, building automated infrastructure that captures every show, every night, every artist with studio-quality multitrack recording (24bit/48kHz) and 12-hour turnaround times.

Our three core principles guide everything we do:

1. 1. Artist-First: Music starts with the artist. So do we. Nothing gets shared, sold, or streamed unless the artist says so.
2. 2. Access to All: Whether an artist has two fans or twenty thousand, we\'re here for you.
3. 3. Inclusive Innovation: To us, innovation means building systems that include everyone: artists, venues, and promoters. Our revenue-sharing model reflects that.

The Role

This is a unique opportunity at the intersection of Backend and DevOps roles. You will architect, build, and maintain systems that power Venue, Artist, and Fan experiences of Setmixer, as well as collaborate with the hardware and AI teams on the backend of our growing recorder IoT device fleet.

This role is ideal for someone who enjoys working independently in small, agile teams and wants to make a meaningful impact on the music industry.
