The Role

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.

To make tomorrow's top games, developers on the Roblox platform need more than just a scripting environment that works–they need modern languages features, advanced programming interfaces, an efficient set of script libraries, a comprehensive suite of development tools, and an ultra-fast, multithreaded runtime. Join our Game Engine Programmability team and help define the Roblox scripting language as well as help drive the development of a new set of programming interfaces and advanced tooling features that will be used by millions of developers daily. 

As a Senior Software Engineer on the Roblox Game Engine Programmability Team,
You Will:

  • Contribute to the design and development of new features in Luau across its highly-efficient type solver, analysis tools, compiler, virtual machine and runtime stack.
  • Take ownership of new feature development from concept and prototyping to deployment and maintenance.
  • Improve the adaptability and performance of existing components.
  • Collaborate with engineers across various engine and partner teams to build collaborative solutions.
You Have:
    • Proficiency in C++ and a solid understanding of programming languages, compilers and runtime.
    • Over 5+ years of experience in developing and deploying user-facing software development tools such as programming language compilers, virtual machines, and runtime APIs.
    • A Bachelor's or Master's degree in Computer Science or equivalent experience.
    • Enthusiasm about modern programming languages, compilers, virtual machines, just-in-time compilation, garbage collectors and runtime domain.
    • Desire to constantly learn and keep abreast of the latest trends in scripting languages and programming environments.
    • Experience with API and tool development, game development, and distributed systems. Experience with Lua or Luau scripting is a plus.
    • A strong grasp of industry standards, best practices, and design patterns.
    • The ability to analyze and approach problems from multiple perspectives, weighing the advantages and drawbacks of different solutions.
