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.

About the Role

~1 min read

Lead and grow the Geometry Scalability team — a group of senior and staff C++ engineers working at the intersection of real-time graphics, geometry processing, and large-scale systems — and own the vision, roadmap, and execution for systems like SLIM and our geometry generation and level-of-detail pipelines.
Evolve geometry scalability over a 1–3 year horizon, driving new algorithms and architectures in areas such as mesh simplification, level-of-detail generation, and scalable skinning/transcoding pipelines — extending today's capabilities from static environments to avatars, articulated models, and animated content like vehicles and interactive props.
Own end-to-end delivery for geometry scalability systems — design, implementation, testing and performance validation, rollout, monitoring, and long-term maintenance — with clear execution practices that lead to predictable, high-quality results.
Coordinate across teams including rendering, avatar, physics, and content platform, ensuring dependencies are understood and risks are managed early, and partner with research and senior individual contributors to translate cutting-edge techniques into robust, production-quality engine features.

4+ years of engineering management experience, including leading senior and staff engineers on complex engine or platform projects.
A proven track record of shipping large‑scale C++ engine or real‑time 3D systems (for example, game engines, graphics or geometry pipelines, simulation, or large content platforms).
Experience owning a multi‑quarter or multi‑year technical roadmap that required cross‑team coordination, staged rollouts, and ongoing iteration on performance and quality.
Strong background in 3D computational geometry and numerical methods: mesh processing, level‑of‑detail generation, geometry simplification, and linear algebra.
Deep expertise in modern C++ and low‑level performance optimization on CPU and/or GPU, ideally in real‑time engines or large‑scale rendering/geometry pipelines.
Familiarity with skinning, animation, and avatar systems (bones, accessories, layered clothing) and how they integrate into geometry and streaming pipelines is a strong plus.
Demonstrated ability to build and maintain a healthy team culture: clear expectations, predictable delivery, psychological safety, and direct, constructive feedback.

Someone who has experience working directly with or building for user‑generated content ecosystems or creator platforms where scalability, robustness, and backwards compatibility are critical.
Background with scalable content streaming systems, such as cloud‑based content transcoding and delivery pipelines for 3D assets.
Prior contributions to graphics, geometry, or simulation research (for example, publications or conference talks) or experience productionizing such techniques in shipped products.
