Role
Who you are
- Proven Expertise: 8+ 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
- Applied 3D Systems Experience: Demonstrated hands-on experience building at least one production system involving real-time 3D rendering, mesh or geometry processing, LOD, animation/skinning, spatial data, 3D asset pipelines, or GPU/client performance. Deep specialization in one area is not required, but meaningful hands-on experience is
- 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
- Ownership in Ambiguity: A track record of driving work end-to-end when the problem wasn't fully specified: defining the approach yourself, seeing it through implementation, rollout, and production consequences; gathering more information when requirements didn't 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
What the job involves
- The Geometry 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
- 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
- Lead by example: drive projects end-to-end, mentor other engineers, and help set a high bar for technical quality and code health on the team
Our take
Online gaming may be a well-established space, but Roblox has distinguished itself as a leader by empowering its community to build, share, and profit from their own creations - turning game development into an accessible, rewarding ecosystem for millions of users.
In addition to standard games, the platform offers virtual worlds and other experiences to explore and interact with. Its platform provides an online ecosystem for millions to create, socialize, chat, and explore immersive experiences with friends. In fact, in the US its used by two-thirds of children aged 9 to 12.
The platform has faced scrutiny over user safety, but responded by strengthen parental controls and launching initiatives like its "Parents Council". This move to address these issues, atop its strong financial performance and record payouts to developers, showcase Roblox's trajectory as one of innovation and impressive growth.
