The opportunity
We are hiring for a Senior Software Engineer to join our Web Platform team here at Unity. Unity's Web platform lets games and real-time 3D content run in a browser, on any internet connected device. Browser capability has moved fast, browser gaming is going through a revival, and the Unity Web runtime is what 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.
In this role, you will own meaningful areas of the runtime outright. This is not website development. We embed Unity inside the browser, and the problems are the deep ones: making a single-threaded platform multi-threaded, cutting megabytes out of a build, getting a game playable in seconds rather than minutes. You will work alongside engineers who helped invent the browser technology we build on, and you will help the people around you grow.
What you'll do
Own meaningful areas of the Unity Web runtime, from design through to release
Research, design and implement optimizations to the Web build target, such as stripping unused code from builds and progressively loading assets as a game needs them
Improve download size, load and startup performance for Web builds, and set measurable targets for it
Solve uncommon, low-level problems across C++, C# and JavaScript, for example bringing multi-threading to parts of the runtime that are single-threaded today
Partner with teams across Unity who build on the Web platform, translating what they need into platform work
Mentor teammates and help set the bar for code quality across the team
Keep Unity at the frontier of the Web's constantly evolving capabilities
Requirements
Deep, hands-on proficiency with C++ in performance sensitive code
Development experience with WebAssembly, using Emscripten and/or LLVM
Ability to decompose complex technical problems and complete them on your own technical judgment
Experience profiling, debugging and optimizing across the native and browser boundary
Working knowledge of C# and JavaScript
Effective written/verbal communication with peers, managers and key decision makers in other teams
A proven track record of mentoring engineers and raising code quality standards
You might also have
Experience contributing to a browser engine or browser runtime
Deeper domain knowledge of rendering, physics or audio in a real-time 3D engine
Familiarity with compression methodologies and build size reduction
