Job description
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 Senior Backend Engineer on the User Communities team, you’ll own the backend systems that power social engagement features, such as Announcements, Forums, Polls, Bug Reporting, and more, for millions of players, as well as the control plane, permissions layer, and tools for Creators to build, grow, and moderate thriving communities on Roblox.
Your day-to-day will focus on building and scaling the systems that bring players and Creators together, both inside and outside the experience. On the player side, that means creating places where people can find and connect with other members of the community, such as having conversations about the experience, discovering the latest updates, and sharing their feedback. On the Creator side, that means giving them the tools and controls to shape those spaces, including configuring custom roles, creating content, moderating discussions, and converting organic excitement into lasting engagement.
Getting there means driving architectural decisions, reasoning through trade-offs, influencing stakeholders, championing user-first safety standards, and defining developer-facing APIs that help creators make more engaging spaces. You'll work closely with frontend and backend engineers, product, design, and data scientists across teams, and you'll have real influence over our technical and product direction.
If you're an experienced engineer who gets excited about large-scale distributed systems and wants to shape the way millions of people connect inside virtual worlds, we'd love to talk.
You Will:
• Shape the backend engineering culture across the Communities team. Your influence extends beyond your immediate pod to improve how we build, review, and ship software across the entire org.
• Act as the technical lead for cross-functional initiatives. Collaborate across multiple pods alongside product, design and both frontend and backend engineers.
• Take end-to-end ownership of projects. Drive initiatives from the creation of comprehensive technical plans and architecture through to successful launch, iteration, and measurable impact.
• Be hands-on in the codebase. Our senior engineers actively develop the platform and review the code.
• Design empowering systems. Build architectures that enable Roblox creators and players to actively engage with each other both in-experience as well as on the platform.
• Promote exploration and experimentation among engineers, advocating for new technologies and flows that promote user experience, with a safety-first mindset.
You Have:
• 8+ years of backend software engineering experience, with demonstrated ownership of large-scale production systems.
• Strong distributed systems fundamentals — experience architecting and operating large, complex systems that handle high throughput
• Deep proficiency in at least one server-side language (e.g., C#, Java, C++) and comfort navigating large, complex codebases.
• Ability to author clear technical specs, reason about trade-offs that hold up at scale, and influence teams towards the correct collective architecture.
• Track record of broad system architecture — from ambiguous requirements through production, including cross-functional coordination with product, and alignment with multiple engineering teams.
• Strong engineering fundamentals — code quality, test coverage, observability (logging, metrics, alerting), and incident response.
You Are:
• Kind and generous: You treat colleagues with respect, assume good intent, and go out of your way to help others succeed. You believe technical excellence without kindness is not enough.
• Product-opinionated: You don't just execute plans, you proactively shape our roadmap, and push for the right product outcomes.
• Hands-on: You write code, review code, and stay close to the product. You're not looking for a role where you stop building.
• An AI advocate: You actively push the boundaries of AI-assisted development for yourself and your team.
• Continuously growing: You take pride in your craft and hold yourself to a higher standard each quarter.
