We9re 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.
We9re 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 4 ages up4 from kids9 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 high-performance systems in domains such as game engines, real-time simulation, robotics, AR/VR, or similar.
- Strong C++ Experience: Deep proficiency in C++, with a focus on writing clean, efficient, and maintainable code in large codebases.
- Real-time Performance Mindset: Experience diagnosing tradeoffs among CPU/GPU time, memory, loading latency, visual quality, and frame-time stability on constrained platforms such as mobile or console.
- Applied 3D Systems Experience: Demonstrated hands-on experience building production systems involving real-time 3D rendering, mesh or geometry processing, LOD, animation/skinning, spatial data, 3D asset pipelines, or GPU/client performance. Not required, but a major plus.
- Ownership in Ambiguity: A track record of driving work end-to-end when the problem wasn9t fully specified: defining the approach yourself, seeing it through implementation, rollout, and production consequences; gathering more information when requirements didn9t make sense.
- Collaboration and Communication: Ability to work effectively across teams (Engine, Rendering, Avatar, Studio, and developer-facing teams) and explain complex technical topics clearly to different audiences.
