Senior Platform Backend Engineer

The opportunity 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.

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

What we're looking for

• Substantial professional experience designing, building, and operating backend services in production
• Strong proficiency in one or more modern backend languages, and the flexibility to work across several
• Solid grounding in distributed systems - API design, data persistence, state management, and the trade-offs between them
• Hands-on experience with cloud platforms and containerized, orchestrated deployments
• A track record of owning services in production, including monitoring, debugging, and incident response
• Pragmatism and comfort with ambiguity - you ship iteratively and make sensible trade-offs under real deadlines
• Clear communication and easy collaboration with both technical and non-technical colleagues

You might also have

• Experience with real-time or multiplayer systems - WebSockets, collaborative editing, or state synchronization
• Experience with the Unity Engine or other interactive 3D technology
• Experience building backend services for games or interactive media

• Relocation support is not available for this position
• Work visa/immigration sponsorship is not available for this position
