WHY SAFETY?
At Roblox, our commitment is to connect a billion people with optimism and civility. The Safety organization is dedicated to leading the way in fostering civil immersive online communities. We employ systematic strategies to detect, eliminate, and prevent harmful accounts, content, and behavior, ensuring that Roblox accounts remain secure and uncompromised. Our expertise covers a wide array of technological domains, including machine learning, 3D model classification, experimentation, automation, detection workflows, and AI-driven text filtering. Collaborating closely with product teams, we leverage our toolset to uncover new possibilities, influence product development, and enhance safety features while measuring their impact on our community of users and developers. This work is essential in maintaining Roblox as a safe, civil, and inclusive space, promoting positive interactions among individuals worldwide.
WHY ALT DEFENSE?
Safety and civility are our top priorities at Roblox. The Alt Defense team is at the forefront of this initiative, tasked with addressing one of the most challenging adversarial issues on our platform: Alternate Account Detection and Prevention. When malicious users are banned from Roblox, they often attempt to return under new identities. Our mission is to thwart these attempts immediately. As the Technical Lead for this team, you will design and implement a cutting-edge detection system operating at an enormous scale—analyzing billions of accounts and identifying repeat offenders within minutes. Additionally, you will support various use cases for alternate account detection throughout the organization. You will report directly to the Senior Engineering Manager of the Account Identity Team.
