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.The Roblox Avatar defines the identity of every Roblox player and is one of the core pillars of the Roblox metaverse. We are looking for a Senior Software Engineer to build the automation, performance analysis, and developer-facing systems that keep avatars high-quality, performant, and reliable at scale.

In this role, you will own end-to-end tooling and infrastructure - from backend services to frontend dashboards - that allow us to measure, understand, and act on challenges across the entire avatar stack. Your work will directly enable us to ship better avatar experiences and will give internal teams and millions of Roblox creators the visibility and controls they need to build great content.

You will report to the Engineering Manager for Avatar Heads and Bodies.

You Will:

Build automation and analysis systems for Roblox’s next-generation avatars, designing pipelines and services that continuously evaluate avatar performance, quality, and integrity at scale.

Develop both backend and frontend tooling: robust backend services for large-scale data collection, processing, and validation, and intuitive web/UI surfaces that let partner teams and creators inspect results and take action.

Instrument and analyze avatar performance across platforms, creating metrics, dashboards, and workflows that help us quickly identify and fix performance bottlenecks in the avatar stack.

Improve the robustness of the avatar and engine stack, working across boundaries with engine and platform teams to ensure avatar systems are stable, scalable, and efficient.

Partner closely with art, design, and other engineering teams, translating their needs into automation, diagnostics, and self-service tools that unlock faster iteration and higher-quality content.

Lead technical direction for avatar automation and performance systems, setting a high bar for design, code quality, and operational excellence, and mentoring other engineers on best practices.

You Have:

Proven expertise: 5+ years of professional experience in game development, real-time systems, computer graphics, or a related field, with a track record of delivering high-quality, production systems.

Mastery of distributed systems and automation: Expert-level proficiency in designing and operating large-scale pipelines and services (e.g., data processing, validation, or analysis systems) that are reliable, observable, and easy to extend.

3D / avatar domain familiarity: Experience with real-time 3D engines, geometry/modeling, character systems, or similar domains, giving you the context to reason about avatar architecture, constraints, and failure modes.

Performance-driven mindset: Demonstrated ability to identify, analyze, and fix performance issues—profiling, digging into metrics and traces, and driving improvements across diverse hardware, especially mobile.

End-to-end ownership: A proactive, self-directed approach. You are comfortable owning projects from problem definition through design, implementation, rollout, and iteration.

Strong collaborative skills: Clear communication and a track record of working with cross-functional partners (engineering, art, design, product) to align on goals, make tradeoffs explicit, and drive impactful outcomes.
