Software Engineer, Foundation AI

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 were 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. Were 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 youll 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.

The Agent Infra team builds the infrastructure that runs autonomous AI agents at Roblox for millions of creators building experiences on our platform and for thousands of Roblox engineers shipping production code every day.

Agent workloads break the assumptions most infrastructure is built on. They run for hours instead of milliseconds theyre non-deterministic they execute code nobody wrote and they need real credentials against real systems to be useful at all. Making that safe durable and cost effective at Robloxs scale is the hard problem our team is solving.

As an early member of the Agent Infra team youll work alongside an experienced engineering team on systems that are already in front of real users at scale in a field that didnt exist two years ago.

• Early in your career: 1-3 years of professional experience or a recent grad; with strong CS fundamentals and an interest in learning infrastructure distributed and agentic systems.
• Someone who builds things: You have projects internships or open-source work youd genuinely enjoy walking us through.
• Into AI agents. Youve built something with them even something small and you can tell us what broke.
• Comfortable writing real code in Go Python Rust or similar and quick to pick up whatever you havent used yet.
• A fast learner who asks good questions digs into things you dont understand and doesnt wait to be told what to do next.

• Build and shape the platform that runs Robloxs agents; across internal and external products at massive scale.
• Work on agentic infrastructure ensuring that were able to build optimal security and scalable systems whilst keeping pace with new advances in the industry.
• Continually learn and adjust your understanding of the systems we are building and what is capable with AI agents.
• Experiment and share your agentic workflows ensuring that the Agent Infra team is helping shape the future of work at Roblox.
