Senior Software Engineer - Safety Experience

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. WHY SAFETY? At Roblox, we strive to connect a billion people with optimism and civility, and the Safety organization’s mission is to become the leader in civil immersive online communities. We systematically detect, remove, and prevent problematic accounts, content and behavior, and we make Roblox accounts secure and free from compromise. We cover a broad area of the tech spectrum, including machine learning, classifiers for 3D models, experimentation, automation, detection workflows, and AI-powered text filters. Aligned and partnering with product teams, we use this toolbelt to discover new opportunities, influence and shape the product roadmap and prioritization, build safety products, and measure the impact on our community of users and developers. In doing so, we keep Roblox safe, civil, and inclusive, and we foster positive relationships between people around the world. WHY Safety Applications? As we scale, the complexity and volume of safety threats have grown exponentially, making Trust and Safety the single most critical engineering problem we face. The platform’s ability to achieve its mission hinges entirely on the foundational tooling we build. We are not just responding to incidents; We are building the scalable operating system for all of Roblox’s Trust & Safety strategy. As a Senior Engineer on the Safety Application pod within the Safety Experience, you will be instrumental in developing our in-house safety applications. This role emphasizes building intuitive, scalable, and AI-agentic-powered tooling for daily Roblox safety acts. If you are passionate about solving complex, high-impact problems in an adversarial landscape, this is the team for you. You will report to the Engineering Manager of the Safety Application Team. You Will: - Architect and Lead End-to-End Systems: Assume ultimate technical ownership for the lifecycle of complex, full-stack systems within Safety labeling and Investigative tooling. Drive the technical strategy from specification through implementation, rollout, and iteration, actively shaping and influencing the pod's broader roadmap. - Spearhead Cross-Functional Alignment: Act as the primary technical anchor for Operations, Product Managers, and partner safety pods. Take the lead in resolving highly ambiguous workflows, translating complex business pain points into scalable, extensible technical architectures while proactively managing tech debt and long-term platformization goals. - Pioneer Architectural Vision: Define and drive the architectural direction for the next generation of safety applications. Lead the integration of advanced AI methodologies (including LLMs and agentic workflows) to build highly effective, scalable moderation solutions. - Design and Scale Core Primitives: Architect, build, and evangelize shared moderation primitives (e.g., Compliance infrastructure, Quality Assurance, Traffic Routing, workforce management, and agentic AI labeling frameworks). Empower external integrator teams by creating frictionless, self-serve onboarding pathways for new safety surfaces. - Drive Multi-Quarter Initiatives: Lead large-scale, cross-organizational technical initiatives. Navigate complex dependencies, resolve cross-team blockers, and align disparate groups to ensure the widespread adoption and operational success of our core safety applications. - Act as a Technical Multiplier: Elevate the engineering standards of the team. Take responsibility not just for your own project execution, but for mentoring engineers, driving design reviews, and establishing best practices across the safety platform ecosystem. - Partner with Leadership: Partner closely with engineering leadership to define technical priorities, reporting directly to the Manager of Safety Applications. You Have: - 7+ years of experience in software development. - Distributed Systems Architecture: Proven ability to design and implement robust, high-throughput microservices (handling thousands of requests per second) while maintaining a strict focus on system safety and security. - Safety-Driven Mindset: A strong commitment to designing, implementing, and maintaining systems that prioritize user s
