Software Engineer, Foundation AI

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.

About You

• 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.

Responsibilities

• 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, secure, 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.
