Description
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.
Safety and Civility is Roblox's #1 priority, and our mission is to protect our global community. As a Senior Software Engineer on the Asset Safety team, you will serve as a hands-on technical leader building resilient, highly scalable systems to ensure millions of daily user-generated assets remain safe and civil. You will tackle complex engineering challenges across diverse modalities—including 3D content, code, images, and video—operating at platform-wide scale across billions of engagement hours while maintaining efficient, low-frequency high-throughput processing.
You will:
- Architect, build, and optimize end-to-end ML-based safety moderation systems to detect and mitigate problematic content using scalable distributed architectures and event-driven, asynchronous workflows.
- Deliver production-grade, AI-driven safety products end-to-end in a dynamic environment, driving execution from initial ideation to deployment while aligning key cross-functional stakeholders.
- Drive technical roadmap decisions, implement robust observability and reliability practices, integrate strict security and compliance standards, and enforce rigorous testing and CI/CD pipelines while mentoring engineering team members.
- Partner closely with Moderation Operations, Product Management, Data Science, and partner engineering teams across Roblox to deliver cohesive safety solutions.
You have:
- 5+ years of professional software engineering experience designing, building, and deploying large-scale ML infrastructure and distributed production systems.
- Deep backend engineering expertise in high-capacity microservices, advanced distributed architecture, scalable data storage and management, and event-driven asynchronous processing.
- Proven technical leadership with a track record of architecting, building, and deploying low-latency, distributed ML services to production end-to-end.
- Practical experience with streaming and messaging platforms (e.g., Apache Kafka, Apache Flink), end-to-end testing, CI/CD pipelines, security compliance, and comprehensive system observability.
- Hands-on experience with computer vision techniques and multi-modal architectures spanning image, audio, video, and 3D content modeling.
- Experience fine-tuning large Vision-Language Models (VLMs) is a plus.
You are:
- Resourceful: Adaptable in fast-moving environments, with a track record of driving solutions through complex challenges.
- Analytical: Driven to investigate large, complex, and ambiguous technical challenges, using data to quantify problem scope and measure solution effectiveness.
- User-Oriented: Committed to prioritizing the needs of platform users and internal technical partners when designing and scaling backend architecture.
- Team-Oriented: Dedicated to elevating engineering peers, serving as an active mentor, and cultivating a high-standard culture of engineering excellence.
- Mission-Oriented: Focused on core organizational goals, bringing strategic foresight and adaptability to balance long-term technical vision with immediate business impact.
