About 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:
Artist-First: Music starts with the artist. So do we. Nothing gets shared, sold, or streamed unless the artist says so.
Access to All: Whether an artist has two fans or twenty thousand, we're here for you.
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.
Location: Remote with a strong preference for London/UK-based candidates
Requirements
Solid experience architecting, building and maintaining cloud-native applications on AWS with TypeScript, using infrastructure-as-code frameworks like SST/Pulumi/CDK/Terraform
Proficiency with relational databases and writing SQL (preferably Postgres), using query builders or ORMs like Drizzle/Prisma/Kysely/TypeORM/etc.
You should feel comfortable with schema migrations and be unafraid to write custom queries to answer business questions
Good understanding of event-driven systems and cloud building blocks: message brokers, queues, APIs, tasks, logs, cron jobs, CDNs, etc., and how to use them on AWS
Good grasp of serverless vs container-based deployments and the involved trade-offs
Must have experience with AWS Lambda and Docker container deployment on AWS (ECS or others)
Solid TypeScript skills, preferably with experience of working in a monorepo setting with code sharing, using schema libraries like zod and domain-driven module segregation
Minimal familiarity with frontend stacks like React + Vite/NextJs, frontend deployment options, and client code options for accessing REST/RPC APIs
Bonus/Nice-to-have
Passion for music - while not required, a love of live music and understanding of the music industry and music production will help you connect with our mission
Experience with AWS IoT: MQTT messaging, Greengrass deployments, etc.
Hands-on experience with sync engines - technology behind apps like Figma and Linear
Experience with Google Cloud: BigQuery/Datastream for analytics pipelines, spinning compute engine instances for AI purposes
Strong Linux skills, comfortable with ssh
