## Description

As a Senior Backend Engineer on the Unity Studio team, you will own the cloud services behind the product: real-time multi-user collaboration, build and publishing pipelines, and the platform APIs the editor is built on. You will join a fast-moving, cross-functional team where your work ships quickly and directly shapes the product.

You will collaborate closely with engineers, designers, and product managers from day one. As a senior member of the team, you will help set the technical direction, raise the engineering bar, and mentor others as the team grows.

What You'll Be Doing

 * Design, build, and operate the backend services behind real-time collaborative editing, game publishing, and content delivery
 * 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
 * Champion reliability and observability, and help the team respond to and learn from production issues
 * Mentor other engineers and raise quality across the team through code review and design feedback
