Full Job Description
Spotify's messaging platform reaches over 1.4 billion users and delivers tens of billions of messages across email, push, and in-app channels. Beacon is the team behind Quicksilver, the internal platform operators use to create, localize, target, and launch those messages. We're looking for a Senior Engineer to help us build intuitive, reliable tools that power how Spotify communicates with listeners at scale.
What You'll Do
Build and evolve Quicksilver UI, Spotify's multi-channel messaging platform, where operators author, preview, and deliver in-app messages, emails, and push notifications across markets and locales.
Own frontend features end-to-end, from component design and implementation in React and TypeScript through server-side creative rendering.
Work across the stack when needed, including debugging Java and Apollo services, evolving gRPC, Protobuf, and REST API contracts, tracing data through BigQuery, and improving pipeline output.
Support multi-market and localization workflows, helping creatives render reliably across locales and enabling smooth new-market launches.
Partner with product and design to shape features and improvements based on operator needs.
Improve the developer experience through stronger testing infrastructure, build performance, component documentation, and integration tooling.
Contribute to architectural decisions and technical direction as the platform evolves.
Who You Are
You have experience building complex web applications with TypeScript and modern UI frameworks, including React or similar technologies.
You understand state management, GraphQL and Apollo, component-scoped styling, and reusable component-library design.
You have built tools or platforms for internal users and care about creating intuitive, reliable operator experiences.
You are comfortable working across frontend and backend systems, including reading or modifying Java services and working with API contracts such as gRPC, Protobuf, or REST.
You can work with Scala/Python when pipelines or APIs need attention and navigate cloud infrastructure and data tools such as GCP, GKE, BigQuery, or GCS.
You make thoughtful decisions about technical debt and can clearly communicate the tradeoffs between maintaining, improving, and migrating systems.
You have experience working across shared codebases and understand the collaboration needed when teams depend on common components and services.
You may also bring experience with data pipelines, LLM applications such as RAG or vector search, or server-side rendering.
Where You'll Be
We offer you the flexibility to work where you work best! For this role, you can be within the North Americas region as long as we have a work location.
This team operates within the Eastern Standard time zone for collaboration.

About Spotify
Spotify is a Swedish audio streaming and media services provider, launched in October 2008. The platform is owned by Spotify AB, a publicly traded company on the New York Stock Exchange since April 2018. Spotify's primary business is providing an audio streaming platform, with the company claiming that it had 345 million active monthly users and 155 million paying subscribers as of December 2020. Unlike physical or download sales, which pay artists a fixed price per song or album sold, Spotify pays royalties based on the number of artist streams as a proportion of total songs streamed on the service. Spotify distributes approximately 70% of its total revenue to rights holders, who then pay artists based on their individual agreements. Spotify has faced criticism from artists and producers including Taylor Swift and Thom Yorke, who have argued that it does not fairly compensate musicians.
