Unity Studio is our industry focused, cutting-edge, browser-based real-time 3D authoring tool. Studio's next chapter takes it into gaming, with an ambitious vision for how real-time 3D experiences are created, shared, and played on the web. 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.
