## About the role

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. 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. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Demonstrated experience: 8+ years building and operating backend, distributed, or infrastructure systems in production, including systems you designed that held up at scale for years
- Deep expertise in at least one of our core domains: workflow orchestration, scalable backend infrastructure, agentic runtimes, or secure sandboxing and access
- Hands-on: You spend most of your time building, and you write production code in Go, Python, Rust, or similar
- Agent-native: Agents drive your daily work. You’ve experimented with swarms, loops, and orchestration, you have strong opinions on harness and model choice, and you’re constantly evolving your agentic workflow
- Experienced with agents in production: You’ve run agents against real systems, seen how they fail, and know what the infrastructure underneath should do about it
- Bachelor’s degree or equivalent experience in Computer Science, Computer Engineering, or a similar technical field
