Fullstack Engineer - Subscriptions

We are looking for a Fullstack Engineer to join the Customer Service Platform (CSP) team. This team is at the forefront of Customer-Service Metamorphosis, a major transformation dedicated to preparing Spotify for an agentic AI future. Our mission is to ensure that AI enhances 100% of support interactions, from smarter self-service and proactive insights to sophisticated bot conversations and augmented tools for our human advisors. By building a nimble, AI-compatible technology stack, we empower millions of users to resolve their needs intuitively while ensuring our service model remains faster, smarter, and more human.

In this role, you will participate in an organisation where engineering, product, and data collaborate to build an AI-oriented technology suite. We leverage best-in-class vendor offerings for commoditized AI capabilities so that our R&D efforts can focus on the Spotify-specific integrations and innovations that drive the most value.

You will help build and maintain the foundational systems that position AI as a central hub in the CSP landscape. You will contribute to the development of a centralized "CS AI Agent," architect a robust trust and safety layer to protect our users, and create a standardised data model that allows AI to understand a user’s full history and context. Your work will involve transforming core customer service actions into a platform of reusable capabilities, ensuring that every support experience, whether AI-driven or human-led is consistent, reliable, and secure

What You'll Do:
Architect, develop, and operate services that form the core of the Customer services platform landscape. Collaborate with cross-functional working groups to design and implement a standardized data model and unified API structure, enabling agentic AI to reason about a user’s full context and history across all support surfaces. Develop the technical integration of vendor offerings, building the necessary abstractions to maintain control, interoperability, and long-term flexibility. Engineer a robust, custom-built Trust and Safety layer to provide technological guardrails for generative AI, proactively preventing harms related to data privacy, payment fraud, and brand reputation.

Who You Are:
You have strong experience with React and modern JavaScript/TypeScript You have hands-on experience with Next.js (SSR/SSG, routing, data fetching patterns) You have experience building production web applications (performance, accessibility, security, observability) You are familiar with testing web applications (e.g. Jest, React Testing Library, component/integration tests) You have a strong understanding of HTML, CSS, and responsive design You are comfortable with Java or Python

Where You'll Be:
This role is based in London or Stockholm. We offer you the flexibility to work where you work best! There will be some in person meetings, but still allows for flexibility to work from home.
