Senior Design Engineer

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 were 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. Were 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 youll 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.

As a Design Engineer on the Design Acceleration team youll be an individual contributor focused on evolving the systems and processes which power Robloxs design organization through scalable systems AI integrations and custom tooling. Our team is responsible for building the orchestration layers and internal tools that empower designers and engineers to work faster and more cohesively. You will help build internal tools like Figma plugins and design utilities that empower designers and engineers to work faster and more cohesively.

You have experience at the intersection of systems engineering and design tooling. You understand design systems but your superpower is building the backend services APIs and data models that allow those systems to scale. Your work will help ensure our design tools AI agents and prototypes not only inspirebut deploy seamlessly into production environments.

You will:

• Architect and build scalable backend services and APIs that connect our design tools to AI models and production environments (Roblox Studio).
• Develop agentic workflows and orchestration layers (such as Model Context Protocol servers) to enable natural language generation of UI components layouts and prototypes.
• Build automated CI/CD pipelines and infrastructure to abstract away complex DevOps workflows creating zero-config development environments for non-technical designers.
• Design and maintain the data architecture that connects our design system to our AI data sources ensuring design tokens and components are programmatically accessible and synced across multiple platforms.
• Create internal tools develop plugins for tools like Figma and Cursor and build web apps focused on design linting code generation and automated compliance at scale.
• Serve as the deeply technical bridge between core engineering AI research and product design ensuring our design acceleration tools are secure performant and structurally sound.
• You will report to the Manager of Design Acceleration.

You have:

• 6 years of software engineering experience with a strong focus on full-stack or backend development systems architecture and API design.
• Demonstrated experience building scalable internal services not just frontend interfaces.
• Familiarity with LLM orchestration agentic workflows and AI protocols (e.g. MCP).
• Experience with cloud infrastructure feature-flag management version control (GitHub Enterprise) and automated deployment pipelines.
• Strong understanding of Figma plugin architecture and how to programmatically parse and manipulate design data at scale.
• (Nice to have) Experience with Roblox development Lua/React-Lua or game-engine UI architecture.
• (Nice to have) Experience with ASTs (Abstract Syntax Trees) compiler logic or automated code generation.
