About The Position

In this Senior Frontend Engineering role, you will be a key contributor in shaping the future of Roblox’s application surfaces across our User, Creator, Economy, and Ads teams. You will develop the architecture and technical direction of our frontend stack for consumer-facing surfaces, working across teams and technology platforms to ensure our solutions are universal and scalable. This role requires defining how all our frontend pieces fit together, from the professional tools that empower millions of developers to the high-stakes financial systems and privacy-centric Ad platforms that power our virtual marketplace.
You will have the opportunity to work with modern frameworks and dive into our custom Luau-based tech, bridging the best ideas from the web ecosystem into Roblox’s unique environment to build the "Social Fabric" of the metaverse. If you are excited by the idea of creating the foundation on which dozens of engineers will build new features, architecting universal systems that live seamlessly across mobile, VR, and consoles, then this role will be perfect for you. Join us and help build the frontend platform that enables incredible new experiences for a billion users and a productive, joyful development experience for our engineers.

Requirements

• The Foundation: 5+ years of software development experience, with at least 3+ years specifically focused on large-scale consumer applications.

• The Eye: A "pixel-perfect" mindset with experience building or contributing to a Design System and a deep commitment to WCAG Accessibility standards.
