What they need
- 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
- 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- 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
- 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
- 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
- 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
- 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
