Senior Machine Learning Engineering Manager

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 AI Systems

As Senior Engineering Manager for Safety AI Systems at Roblox youll lead technical efforts and manage a team of experienced engineers to develop innovative AI solutions for multimodal content safety. Youll oversee machine learning systems constructing multimodal model architectures improving data quality training pipelines and model performance to address challenges like real-time multi-verse content understanding and advanced moderation with large vision language models spanning avatars images videos audios text code / data models and their composites.

In close collaboration with product policy and Trust & Safety teams youll design large-scale systems to detect and mitigate abusive behavior before it harms the community. Youll own critical services at massive scale balancing user freedom with platform civility to protect and empower our users. Your leadership will help ensure Roblox remains a safe inclusive space for self-expression and shared experiences.

You Will

• Own the vision technical direction and execution of machine learning solutions for the Multimodal Safety AI system ensuring these systems effectively detect and prevent harmful content at scale.
