We’re looking for a top-notch Java developer who will shape the technology of the world’s top content recommendation network.

Our principles

  1. Each team is highly autonomous and owns its own services. You develop, you deploy, you wake up at night when your code breaks.
  2. Production code must be safeguarded by unit and integration tests, pass static analysis, go through a gradual deployment process and be automatically monitored for business KPIs. Quality is king.
  3. Peer review through pull requests is our bread and butter.
  4. Use the right tool for the job. Don’t blindly follow the latest fad, but always be on the lookout for what’s out there.

Our scale

  1. We require thousands of servers across multiple data centers to serve our traffic.
  2. > 10k Kubernetes pods.
  3. Many dozens of services and data stores are accessed for each served request. We have a Netflix-style micro services architecture where all pieces must fit together to deliver on performance and correctness.
