Senior Software Engineer - Core UX Studio

Roblox operates a platform where millions of users create, play and share 3D immersive experiences built by a global community of developers. The Senior Software Engineer role in the Core UX Studio team focuses on evolving Roblox Studio, the integrated development environment used to build those experiences. Day‑to‑day work includes designing and implementing UI frameworks, windowing systems and AI‑native features inside Studio, shaping the application’s architecture and OS integration, and contributing to the third‑party plugin ecosystem. You will collaborate with UX designers to define visual, motion and interaction language, build central backend systems that support Studio’s functionality, and lead complex technical projects from planning through delivery. The role also involves mentoring teammates, establishing engineering practices and patterns, and ensuring the platform remains scalable and testable. Ideal candidates have five or more years of experience shipping user‑facing desktop applications, strong C++ skills, familiarity with UI frameworks such as React, Cocoa or WPF, and the ability to work analytically across multiple threads while guiding junior engineers.
