Software Engineer — Unity Studio (Web-based 3D Editor)

The opportunity The Unity Studio team is a group of passionate engineers, designers, and product thinkers building a cutting-edge, browser-based real-time 3D authoring tool. Built with Unity 6 and compiled to WebAssembly, Unity Studio lets creators build and edit 3D environments directly in the browser — no Unity Editor install required. While our current focus is on non-gaming use cases, our ambitious vision is to evolve Studio into a universal, web-based collaboration hub for any Unity project. We're looking for a Software Engineer to join us. You'll work across the full surface of the product — scene editing tools, real-time multi-user collaboration, performance-critical rendering, and cloud-connected asset pipelines — with lots of hands-on coding and deep technical challenges. If you love Unity, care about performance, and get excited about pushing the boundaries of what a browser can do, this role will suit you. This is a rare opportunity to directly shape how millions of creators worldwide author 3D content — building the foundational tools that power the next generation of games and 3D applications. We're committed to maintaining a diverse team, and we welcome and encourage applicants with diverse experiences and backgrounds. What you'll be doing Build and ship features for the 3D editor — from scene manipulation tools to UI panels — using Unity's UI Toolkit, MVVM, and a Redux-style state management layer. Work on a real-time collaboration system, enabling multiple users to edit a scene simultaneously in the browser. Profile and optimize WebGL/WebAssembly performance — tackling load times, memory management, and the unique constraints of a browser-hosted Unity runtime. Integrate with cloud services and 3D asset pipelines, connecting the editor to Unity's ecosystem for asset management, authentication, publishing, and analytics. Strengthen quality and delivery through testing (EditMode, PlayMode, integration), CI/CD contributions, and thoughtful code reviews — while fostering a culture of innovation, teamwork, and technical excellence. What we're looking for Strong C# proficiency in a Unity context — comfortable with modern C# (async/await, pattern matching) and dedicated to writing clean, testable code. Solid Unity experience (3+ years) — you know your way around the Unity runtime, URP, assembly definitions, and the package ecosystem. Understanding of WebGL/WebAssembly constraints — you've shipped or optimized a Unity WebGL build and understand the realities of single-threaded execution, memory limits, and browser sandboxing. Experience building UI with UI Toolkit. 3D graphics fundamentals — you understand meshes, materials, shaders, and rendering pipelines well enough to debug visual issues and reason about draw call performance. You might also have Experience with real-time collaboration systems (CRDTs, operational transforms, or conflict resolution in multi-user editors). Familiarity with 3D asset pipelines and optimization (glTF/GLB, FBX, Draco, KTX2). Experience with cloud infrastructure (AWS, Azure, Docker) or CI/CD pipelines for Unity projects. TypeScript/Node.js skills for developer tooling and CLI utilities. Interest in WebGPU and next-generation browser rendering APIs.
