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.

Discovery UX sits at the intersection of product innovation and high-scale infrastructure. Every Roblox user starts their journey on the homepage, and every Roblox developer needs to find their correct audience. Our team works closely with product and engineering teams across Roblox to bridge this gap by improving the user journey from landing on Roblox to joining an experience. We primarily work on Home, Search, Charts, and Experience Details pages, for both the Roblox website and app.

As a Principal Software Engineer, you will craft robust, extensible systems for high-traffic surfaces. While you are a frontend expert at heart, you are a versatile engineer who isn't afraid to dive into the backend or data pipelines to ship a complete feature. You will drive solutions using React and modern technologies, helping us build efficiently across devices. If you have a deep understanding of frontend architecture and a genuine curiosity for diving into data to understand "the why" behind an experiment, you will be right at home with us.

This role reports to the Engineering Manager on the Discovery UX team.
