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 Full-stack 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:
- Assume ownership of the complete lifecycle for full-stack features within Safety labeling and Investigative tooling, encompassing technical specification, implementation, rollout, monitoring, and iteration, ensuring alignment with the designated pod roadmap.
- Engage in close collaboration with Operations, Product Managers, and partner safety pods to translate ambiguous workflows and pain points into clear requirements and pragmatic technical designs, thoughtfully balancing immediate needs with long-term platformization objectives.
- Define the architectural direction for the next generation of safety applications, integrating Artificial Intelligence methodologies.
- Contribute to and maintain shared moderation primitives (e.g., Compliance, Quality Assurance, Traffic Routing, workforce management, and agentic AI labeling) to facilitate the streamlined onboarding of new safety surfaces by integrator teams.
- Take complete responsibility for projects throughout their entire lifecycle.
- Drive cross-functional engagement and lead technical initiatives to ensure the widespread adoption and success of our core safety applications.
- Report directly to the Engineering Manager of Safety Applications.
You Have:
- 5+ 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.
- Full-Stack Proficiency: Experience with both front-end (e.g., React, Vue, Angular) and back-end technologies (e.g.,= Python, Java, Go) to deliver end-to-end features.
- 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 (5+ 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.
