Comfortable with component-based architecture and state management patterns (Redux/Flux or similar) for building maintainable UIs.
Strong programming skills in one or more scripting languages relevant to frontend and tooling such as TypeScript, Swift or Kotlin, or the ability to quickly learn them, is highly desirable. Familiarity with C++ or other low-level languages is beneficial for understanding our engine integration.
Demonstrated ability to optimize frontend performance and diagnose issues. Knowledge of performance debugging, profiling, and benchmarking techniques on the client side. Passion for ensuring fast, fluid user experiences on all devices.

Comfortable sharing ideas, documenting designs, and collaboratively solving problems in a large engineering organization.
Experience developing applications or libraries across multiple platforms (web, mobile, desktop). Familiarity with building applications that serve users on Web, iOS, Android, Windows, etc. is desirable for ensuring a seamless cross-platform experience.

You will:

Contribute to Scalable Frontend Systems: Work with senior and principal engineers to implement and improve systems that power core Roblox surfaces like Home, Avatar, and Social, helping serve millions of users efficiently.
