Harmony is the critical subsystem responsible for ensuring a stable, enjoyable, and interactive experience for Roblox users across all devices. By intelligently orchestrating and adjusting presentation quality from high-fidelity rendering down to basic interaction. This role offers a unique opportunity to pioneer the application of machine learning to real-time, low-latency systems optimization. You will define the ML strategy for resource management within the engine, moving beyond traditional heuristics to build adaptive systems. You will solve complex, high-stakes resource allocation and quality scaling problems across memory, CPU/GPU compute, battery life, and network bandwidth. We aim to leverage predictive modeling and optimization techniques to handle highly dynamic content and opaque resource signals from the OS, transforming the stability and quality of the global Roblox experience.
