Careers at Roblox

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. The Game Engine team at Roblox works on the systems that power the experiences at the heart of the metaverse. Our code is the technical foundation in our client, editor, and our simulation servers. The Game Engine team is broadly split into departments — Audio-Video-Communication, Avatar, Core AI, Digital Matter, Productivity, and Systems. This position is for the Systems Runtime pod. The Runtime pod builds and maintains the foundational C++ components that power the entire Roblox engine and Studio stack. We own the runtime layer — the performance, efficiency, and usability of the core primitives that every other engineering team relies on. Think of Runtime as the “standard library” and execution engine for Roblox's C++ world. Our ownership centers on three pillars: Concurrency System — our task scheduler and fiber runtime power how work is parallelized across CPU cores, letting teams scale features across platforms while keeping code understandable and debuggable. Memory System — we own the engine's memory allocator stack, tracking pipelines, and observability tooling to make memory behavior predictable and prevent leaks and fragmentation. Profiling and Observability — we build and evolve the MicroProfiler and telemetry pipelines to help engineers diagnose real-world regressions and keep the client fast at global scale. This role centers on our Concurrency system. You will own the scheduler and fiber runtime that the rest of the engine is built on, research and implement the performance work needed for 3K-player servers and genre expansion initiatives, and act as the point of contact other engine teams come to with concurrency asks. You will debug real production failures across PC, Mac, mobile, and console, and build deep intuition for how compilers, CPU architectures, and operating systems interact. A single well-designed primitive or optimization here makes hundreds of internal engineers more productive and millions of player sessions smoother. You Will: Take ownership of part of the engine's Concurrency system — the task scheduler, fiber runtime, and async APIs that every other engine team builds on. Research and implement performance improvements that unblock platform initiatives – unlocking higher fidelity and richer experiences. Serve as a point of contact for concurrency across the org: design reviews, hard parallelism bugs, and asks from other engine teams. Improve the ergonomics, testability, and debuggability of concurrent code across PC, Mac, mobile, and console. You Have: Strong modern C++ (C++17 or newer) in a large, complex production codebase Deep multithreading/concurrency experience — schedulers, thread pools, lock-free programming, atomics, memory models Comfort profiling and reasoning about performance at the OS/CPU level Nice to Have: Game engine or real-time systems experience Fiber/coroutine runtimes, work-stealing or job-system schedulers Cross-platform low-level development (Android, iOS, console) Track record as the go-to expert other teams consult on a system For roles that are based at our headquarters in San Mateo, CA: The starting base pay for this position is as shown below. The actual base pay is dependent upon a variety of job-related factors such as professional background, training, work experience, location, business needs and market demand. Therefore, in some circumstances, the actual salary could fall outside of this expected range. This pay range is subject to change and may be modified in the future. All full-time employees are also eligible for equity compensation and for benefits as described on this page . Annual Salary Range $196,750 — $243,290 USD Roles that are based in an office are onsite Tuesday, Wednesday, and Thursday, with optional presence on Monday and Friday (unless otherwise noted).

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. The Traffic Proxy Services team powers the front line of Roblox — operating the global edge network and high-performance Layer 7 proxies that handle billions of web and API requests daily while defending the platform against large-scale automated attacks. In this role, you'll help pioneer the next generation of our edge infrastructure: replacing legacy proxy configurations with programmable, memory-safe Rust services running on Kubernetes, and building intelligent, automated defense systems. Working alongside principal engineers and key partners across Security, Reliability, and Platform teams, you'll tackle high-stakes systems challenges where efficiency, scale, and uptime are critical. You Are: An experienced systems engineer with 7+ years building and operating backend or infrastructure software, including time owning a tier-0 service in production. Fluent in a systems language. Rust strongly preferred; strong Go experience with the appetite to work in Rust is welcome. Deeply comfortable with networking fundamentals: TCP, TLS, HTTP/1.1 and HTTP/2, QUIC and the internals of at least one production L7 proxy (HAProxy, Envoy, NGINX, Pingora or similar). Able to troubleshoot a live network problem. Familiar with how the kernel and userspace interact, and comfortable tuning the kernel to optimize for efficiency and reliability. Experienced with high-performance packet processing in and around the kernel — kernel-bypass and kernel-path techniques such as eBPF/XDP. Able to independently design, build, and operate systems on Kubernetes end to end, and to reason about node-level behavior when latency and resource isolation matter. Able to write a design doc that survives review by senior stakeholders across several teams, and to disagree productively when it doesn't. Motivated by problems where the blast radius is real and the feedback loop is immediate. Genuinely curious. You pull on the thread until you understand why a system behaves the way it does, and you would rather learn an unfamiliar layer of the stack than route around it. You Will: Design and build high-performance services that sit directly in the request data path, where performance, reliability, and security are of utmost priority. Effectively leverage AI tools to speed up research, development, and troubleshooting while keeping a critical eye Evolve our edge architecture toward something simpler and programmable, migrating policy incrementally with parity testing and exercised rollback. Improve traffic classification and intelligence to detect and mitigate DDoS and abuse traffic. Build feedback loops that automate mitigation and reduce MTTR. Raise the efficiency of the edge Own your work in production as part of the team's on-call rotation, and raise the reliability bar through design, code review, incident review. Collaborate across Networking, Security, Reliability, and Compute to deliver on Infrastructure and company priorities. Be a gatekeeper for a high code quality bar, architectural designs, and pragmatic vs. long-term approaches. Uphold our company vision by putting the Roblox community first and exemplifying our values.
