Tech Stack

Description

You will lead the technical vision for alternate account detection at Roblox, architecting high-scale ML systems using Graph Neural Networks to map relationships across billions of entities and prevent bad actors from returning to the platform. You'll drive the ML roadmap, solve complex adversarial challenges, and mentor a team of ML and software engineers.

Requirements

• MS or PhD in CS, ML, or related field
• 10+ years industry experience in Applied ML
• Expertise in large-scale GNNs and clustering at billion-node scale
• Track record of leading complex ML projects to production
• Adversarial mindset and experience with low-latency ML deployment

Responsibilities

• Lead technical vision for alt account detection platform
• Architect GNN and clustering systems for billions of entities
• Solve ground truth and training data challenges for adversarial usecases
• Develop innovative adversarial approaches to detect sophisticated actors
• Mentor and up-level a pod of ML and software engineers
