Software Engineer, Engine Scalability

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. We’re looking for an outstanding engineering to join our Engine Scalability team. The Engine Scalability team builds the systems that power both Avatars and Environments across Roblox. Our mission is to enable millions of developers to build large, high-fidelity worlds and multiplayer experiences that still run smoothly on phones and low-end devices. We’re the team that lets Roblox experiences evolve from simple platformers into massively multiplayer, open-world, AAA-quality games. This is a CEO-level priority: how Roblox “ages up” from kids’ games to experiences everyone wants to play, by making higher-fidelity avatars and environments performant at platform scale. You Will Design and ship 3D engine systems for avatar and environment geometry, including mesh processing, level of detail, transcoding, streaming, runtime loading, and related performance systems.  Partner closely with other teams (Rendering, Avatar, Studio) and external developers so that the features you build are directly usable to create amazing experiences.  Profile and improve the performance of our game engine across a wide range of devices, with particular attention to mobile.  Drive projects end-to-end, collaborate with other engineers, and contribute to maintaining strong technical quality and code health on the team. You Have Experience: 3+ years of professional experience building and shipping performance-sensitive software. Experience in domains like game engines, real-time simulation, robotics, AR/VR, or similar is a plus. You've contributed to features in a large codebase is a plus.  Knowledge: You're proficient in C++ and write clean, readable, maintainable code.  Hands-on experience with at least one area of real-time 3D (rendering, mesh or geometry processing, LOD, animation/skinning, spatial data, asset pipelines, or GPU/client performance) is a plus.  Ownership: You can take a well-scoped problem from design through implementation and rollout, and you ask questions and gather context when requirements are unclear. Teamwork: You collaborate well with partner teams (Engine, Rendering, Avatar, Studio, and developer-facing teams) and can explain technical topics clearly. Curiosity & Growth: You're eager to learn new technologies, including AI-assisted tools, and apply them to practical problems. You're open to feedback and want to grow your technical scope over time.
