Senior Software Engineer, Client Systems (C++)

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators.

At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there.

A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone.

The Luau App Foundations team is responsible for the core infrastructure of the Roblox application. They bridge the gap between app and the performance-heavy Roblox game engine. This team is building the unified stack that powers mission-critical surfaces like Home, Avatar, and Social for millions of concurrent users. They are the ones who make it possible for "Web-style" development efficiency to exist within a high-performance C++ game engine.

Why is this role exciting:

• Technical Pioneer: You will be writing libraries and modules using C++ inside a world class Roblox proprietary Game Engine.

• Systematic Impact: This is a "Force Multiplier" role. The frameworks and components you build will be used by dozens of other engineering teams to ship their features.

• Complex Problem Solving: You aren’t just building an app; you’re managing smooth data flow through a client that has to perform perfectly on a $100 Android phone and a $3,00
