Senior​/Principal Inference Engineer - ML Platform

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.

• Set technical strategy and oversee development of high scale, reliable infrastructure systems for large-scale inference, especially as we scale up both inference qps and model size.
• Dig into performance bottlenecks all along the inference stack, spanning from model optimizations to infrastructure optimizations.
• Stay abreast of industry trends in machine learning and infrastructure to ensure the adoption of leading-edge technologies and practices.
• Bootstrap and maintain infrastructure for ML Platform components—Serving Layer, Metadata Store, Model Registry, and Pipeline Orchestrator.
• Partner across organizations to build tooling, interfaces, and visualizations that make the ML@Roblox a delight to use.

• 4+ years of professional experience and a tool chest of system design experience upon which to draw to build scalable, reliable platforms for all of Roblox.
• Experience building complex distributed systems that scale to real-time ML inference serving, ideally for real-time recommendation systems serving millions of QPS.
• Experience debugging complicated infrastructure-level performance issues to enable low latency, high throughput inference.
• Bachelor's degree or higher in Computer Science, Computer Engineering, Data Science, or a similar technical field.

• Passionate about supporting and working cross functionally with internal partners (Data Scientists and ML Engineers) to meet and understand their needs.
• A reliability nut: you love digging into tricky postmortems and identifying and fixing weaknesses in complicated systems.
• Ideally familiar with ML model inference frameworks like Triton Inference Server, Tensor
