Senior Software Engineer - Safety Platform & AI Workflows

Every day, over 100 million daily active users come to Roblox to explore, create, play, and connect across 3D immersive digital experiences.

As a Senior Software Engineer on the Safety Foundation team, you will report to the Engineering Manager and help architect, build, and scale the core infrastructure backbone that powers content moderation, user safety, and account security across the entire Roblox platform. In this high-impact backend role, you will help rebuild the Safety Platform into an AI-first infrastructure capable of handling 10x traffic growth, supporting agentic and ML workflows, and providing a developer experience layer that enables internal engineering teams to integrate safety tools in hours rather than months.

Key Responsibilities

• Safety Platform Architecture: Design, implement, and maintain distributed backend services powering real-time content moderation, safety workflows, and user security.
• Developer Experience & Tooling: Build a streamlined developer experience layer that allows cross-functional product teams to easily consume and integrate safety capabilities.
• AI-First Systems Evolution: Evolve the platform architecture to natively support agentic and machine learning safety workflows with low latency and complete auditability.
• Cross-Team Collaboration: Partner with Trust & Safety ML, User Safety, Safety Operations, and Product teams to translate moderation needs into scalable platform capabilities.
• Full-Lifecycle Project Ownership: Drive engineering projects from initial design and prototyping through code review, load testing, deployment, and operational monitoring.
