About this job
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 Networking 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 and have a passion for working on high-performance real-time applications alongside experienced and passionate engineers, you will be right at home on our growing Game Engine team.
You Will:
- Develop engine code in C++ for sub-systems critical to the Roblox game engine
- Work on sub-systems that handle data syncing between server and client, game-aware data streaming, and harmonizing resource usage to ensure gameplay works on various devices with varying CPU and memory capabilities
- Work on every application Roblox develops, from mobile phone clients to cloud-based servers
You have:
- 4+ years of experience and you've worked on deep and challenging problems in large and complex C++ codebases.
- System-level pointers, templates, and raw blocks of memory are tools to write code, not your enemies
- Experience working in the guts of game engine or passion for learning it
- Built systems that work and keep on working reliably
- A curiosity to want to learn and stay up-to-date on technology development
