Role summary

Roblox is seeking a Senior Full Stack Software Engineer to help build Global Actions, systems that ensure core actions function consistently across all Roblox platforms.

The position requires 3+ years of full-stack development experience with React, TypeScript/JavaScript, and data modeling for complex systems.
