Join our global force of 400+ innovators, blending the latest in tech with the greatest in soundtracking, from our Stockholm HQ to offices in London, New York, Los Angeles, Berlin, Paris, Oslo, and Seoul. We’re an industry leader with a startup mentality. We take what we do seriously, but we don’t take ourselves too seriously. Creating and collaborating to transform the sound of streaming, content, and culture. Come join us, and let the world feel your work.

As a Senior Full Stack Engineer in the Customer Platform team, you’ll own and evolve the foundational systems that serve both our B2B customers and individual creators. These include entitlements, workspace hierarchy, memberships, authorization modeling and safelisting. We’re the system of record for account structures and what users are entitled to, so these systems are business-critical.

Our work spans both audiences, from enabling enterprise-ready features to improving the experience for individual creators. That gives you broad impact across the product and a wide variety of challenges.

We have a strong engineering culture grounded in openness and collaboration, with pair and mob programming and dedicated hack weeks for experimentation and learning.

Your key responsibilities include

• Own the team’s systems end-to-end across frontend and backend, from discovery, technical proposals and prototypes through to implementation, testing, deployment and documentation.

• Shape the technical direction and architecture of the team’s platform capabilities, balancing new development with long-term scalability and maintainability.

• Help evolve our platform by refactoring and modernizing established systems, improving their quality, scalability and maintainability.

• Lead larger technical initiatives and drive them from idea to delivery.

• Ensure the stability and reliability of critical systems through monitoring, incident handling and participation in the on-call rotation.

• Use AI tools as a natural part of your daily work, and help the team explore new ways to apply them in how we build.

• Work closely with Product, Design and stakeholders across the business to understand the needs of both B2B customers and individual creators, and turn them into technical solutions.

Requirements

• 6+ years of experience building and maintaining systems, ideally business-critical ones where reliability and quality of execution matter

• Proven experience working across the stack, building and maintaining mission-critical systems end-to-end.

• Strong grasp of distributed systems and system design principles

• Strong Backend development experience in Go, or another modern backend language (Python, Node, Java, Kotlin or similar)

• Strong front-end experience writing code in TypeScript and React.

• Experience operating in cloud environments (GCP preferred, AWS also welcome), including modern CI/CD pipelines

• Ability to turn product and design input into technical specifications, and to communicate clearly with both technical and non-technical stakeholders.

• Hands-on experience with agentic development, and ownership of the quality of AI-generated code.
