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 were 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. Were 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 youll 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 organizations 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 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 platforms 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 Robloxs 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 pods 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 safety data integrity and compliance with safety policies.
• Equivalent experience or a BS in Computer Science Applied Math Physics Engineering Statistics or another technical field.
• Curious to learn new technologies and systematically grow your skills.

You Are:

• Experienced (7 years): You have extensive experience as a full-stack engineer proficient in both front-end and back-end development working on complex production-grade systems end-to-end.
• Analytical & Data-Driven: You possess a strong ability to instrument collect and analyze user interaction data (e.g. A/B testing usage metrics) to inform design decisions and continuously maximize user impact and product performance.
• Versatile & Adaptable: You are proficient across multiple programming languages frameworks and technologies (e.g. modern React #Golang Python relational/NoSQL databases cloud platforms) and can quickly shift focus and master new skills to meet project demands.
• Team-Player & Technical Leader: You are a collaborative team member who actively mentors peers drives technical excellence and takes ownership of leading and delivering key features and projects across team boundaries.
• AI native: You are eager to define and build AI-centric solutions incorporating modern machine learning and agentic AI capabilities directly into the core user experience and system architecture.
