Software Engineering Manager - Network Transport

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.

The Engine Networking Team pulls players together by ensuring the game state is communicated to all, ensures the world those players share actually shows up — the right bits, at the right time, without hitches. As an Engineering Manager for Engine Networking, you will lead and empower a team of engineers who help players experience the game as a nearly synchronous world that streams in seamlessly. Just as the nerves in our bodies coordinate our actions and the bloodstream delivers what every cell needs, the network system coordinates all the computers involved while the asset pipeline delivers the content that brings the experience to life. You will oversee the architecture, execution, and career growth of engineers working across real-time state synchronization and end-to-end asset delivery in your quest to communicate every part of Roblox to every player, as fast as physically possible.

You Have:

- Managed, led, or mentored engineering teams working on high-performance, low-latency network infrastructure or content-delivery/asset-streaming systems in client/server environments.

- Experience driving execution and architectural roadmap for complex multithreaded systems that connect millions of concurrent users worldwide and stream large volumes of content to them reliably.

- Proven track record delivering systems supporting multi-platform deployments - from desktop clients to mobile phone clients to console clients - including the bandwidth, storage, and memory realities each platform imposes.

- Experience building systems in resource-constrained environments where every CPU cycle and byte counts.

- A background in game engine development, game networking, asset pipelines, or content streaming, with deep familiarity in game loop architecture, state synchronization, and how assets are loaded, prioritized, and made available to the running experience. Preferred)

- Experience with the asset delivery path - CDNs, caching layers and cache eviction, download scheduling and prioritization, prefetching, (de)compression and decoding, and streaming/incremental loading under tight memory budgets. (Preferred)
