Back End Developer

At Setmixer, we're bringing live recordings back. Our mission: make sure no live show is ever lost. We capture the raw energy of live performances in studio-quality audio with automated infrastructure that records every show, every night, every artist with 24bit/48kHz quality and 12-hour turnaround times.

Core Principles:

• Artist-First: Nothing gets shared unless the artist says so
• Access to All: Whether you have two fans or twenty thousand
• Inclusive Innovation: Revenue-sharing model that includes artists, venues, and promoters

Unique opportunity at the intersection of Backend and DevOps. You'll architect, build, and maintain systems powering Venue, Artist, and Fan experiences, plus collaborate with hardware and AI teams on our growing recorder IoT device fleet.

Location: Remote (strong preference for London/UK-based candidates)

• Experience architecting cloud-native applications on AWS with TypeScript using infrastructure-as-code (SST/Pulumi/CDK/Terraform)
• Proficiency with Postgres and SQL, using 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.
• Understanding of event-driven systems: message brokers, queues, APIs, tasks, logs, cron jobs, CDNs 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

• Passion for live music and music industry knowledge
• AWS IoT experience (MQTT, Greengrass)
• Sync engines experience - 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/SSH skills
