What the job involves

• Own systems end-to-end - from design and implementation through deployment, monitoring, and running them in production
• Evolve how the platform scales - stateful real-time workloads, session routing, and service fleets in a cloud-native environment
• Define the APIs and service contracts that the editor and partner teams build against
• Strengthen our infrastructure and delivery practices - infrastructure as code, CI/CD, and automated deployment
• Work closely with product and design to turn ambiguous problems into shipped, reliable features
