Job description

San Mateo, CA, United States Early Career ID: 40503

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.

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, they're 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 Roblox’s scale is the hard problem our team is solving.

As an early member of the Agent Infra team you’ll work alongside an experienced engineering team on systems that are already in front of real users, at scale, in a field that didn’t exist two years ago.

You Are

• 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 you'd genuinely enjoy walking us through.
• Into AI agents: You've 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 haven't used yet.
• A fast learner who asks good questions, digs into things you don't understand, and doesn't wait to be told what to do next.

You Will

• Build and shape the platform that runs Roblox’s agents; across internal and external products at massive scale.
• Work on agentic infrastructure, ensuring that we’re 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.
