Software Engineer, Web Platform

The opportunity

We are hiring for a Software Engineer to join our Web Platform team here ty's Web platform lets games and real-time 3D content run in a browser, on any internet connected device. Browsers have advanced enormously in the last few years, browser gaming is going through a revival, and the Unity Web runtime is the technology that makes it possible. Our work also supports an exciting new partnership with a major platform, which puts what this team builds in front of audiences at a scale few browser platforms reach.

You will help maintain and extend the Unity Web runtime alongside engineers who have spent their careers in this space, including people who helped invent the browser technology we build on. This is not website development. We embed Unity inside the browser and work close to the metal across C++, C# and JavaScript. You will have real opportunity to grow, to learn from experienced teammates, and to see your work reach developers all over the world.

• Maintain and extend the Unity Web runtime, contributing features and fixes across the platform
• Help improve the download size, load time and startup performance of Web builds
• Develop, profile, debug and optimize across C++, C# and Java Script
• Scope your work with your manager and teammates, building on established patterns in the codebase
• Investigate and fix issues raised by internal teams and by developers shipping on the Web platform
• Keep pace with the browser's constantly evolving capabilities and bring what you learn back to the team

• Hands-on development experience with C++
• Working familiarity with C# and/or Java Script
• Curiosity about how browsers work under the hood, rather than about building websites
• Ability to profile, debug and optimize native code
• Effective written/verbal communication within a distributed, multi-functional team
• A forward thinker who perseveres on low-level problems that take time to unpick

• Exposure to Web Assembly, Emscripten, LLVM or WebGL
• Experience with real-time 3D or game engines
• Familiarity with code size optimization or compression techniques
