What the posting says

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.

Job Description

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.

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.

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.

You Have:

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.

For roles that are based at our headquarters in San Mateo, CA: The starting base pay for this position is as shown below. The actual base pay is dependent upon a variety of job-related factors such as professional background, training, work experience, location, business needs and market demand. Therefore, in some circumstances, the actual salary could fall outside of this expected range. This pay range is subject to change and may be modified in the future.
