How about you?

Join the User Platform team and contribute to shaping the future of Deezer for tens of millions of users worldwide listening to music on the Deezer mobile apps, website, desktop app and more.
Within the User Platform team, the mission of our team of backend and full stack engineers is to design, build and maintain the services responsible for most of the user-facing features such as the Music and Podcasts homes, the search engine, each user’s playlists and favorites collection, etc.
These services are then consumed by our own web and mobile engineers to build our android, iOS and desktop clients, or exposed in our SDKs for other teams and partners to use.

  • maintain existing features, whether they live in our legacy codebase or are part of our more modern service-oriented architecture
  • contribute to the building and deployment of our new GraphQL APIs
  • monitor in production the good health of our services and the features they provide, and take action when alerts and incidents occur
  • be part of a multidisciplinary team, in direct collaboration with mobile and web developers, product managers, QA analysts, and more
  • work in an agile environment where you can contribute to the problem identification and solution definition processes
  • be part of one or multiple communities of practice based on your expertise and the subjects and technologies you are interested in (e.g. backend CoP, GraphQL CoP, etc.)


What you will need to be successful


  • Proven experience in building and maintaining backend architectures and services in PHP and exposing them through APIs
  • Strong engineering skills, including technical design, code reviewing, testing, etc.
  • Experience working with the following tools and services in a professional environment: Docker, SQL, Memcache, Kafka (or equivalent)
