Principal Engineer - Creator Services

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.

As a Principal Software Engineer on our Creator Services team, you will have an immediate impact on the building blocks of Roblox itself. You will be the technical leader for multiple teams of engineers.

To give some examples of what we do, we run the mission-critical Cross-server Messaging Service, which is crucial for Roblox game developers to implement leaderboards, cross-server announcements, live operations and more. We own the developer APIs for HTTP calls and  player traversal within and between games. We own the platform for all of Roblox’s Cloud HTTP APIs, enabling internal teams to support creator automation of tasks like community management, CI/CD and in-game economy management.

If you enjoy working on modern distributed systems, products for developers, C# and C++ software, and networking challenges alongside highly-experienced and passionate engineers, you will be right at home on our growing Creator Services team.
