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.

As a Senior Software Engineer on our Engine Reliability team, you will have an immediate impact on the building blocks of Roblox itself. The software you build is a very large application that empowers our global community of 2M+ developers to push the boundaries of interactive gaming. Your work will touch every part of the engine, from threading and memory management to physics and scripting. If you enjoy working on C++ software alongside experienced and passionate engineers, you will be right at home on our growing game engine team.

  • Develop engine code that performs well for all user-created games on the Roblox platform
  • Improve scripting, memory management, bootstrapping, and other fundamental layers of the Roblox engine
  • Work on every application Roblox develops, from mobile phone clients to cloud-based servers
  • Report to the Engineering Manager of the Reliability team
  • Experience: you have 5+ years experience and you've worked on deep and challenging problems in complex C++ codebases
  • Systems-level understanding: pointers, templates, and raw blocks of memory are tools to write code, not your enemies
  • Platform domain expertise: you can jump with ease between Windows, OS X, Linux, Android, iOS, and other platforms
  • Curiosity: you want to learn, and stay up-to-date on technology developments
