Senior Machine Learning Engineer (2026, Systems, Embodied AI/NPCs, ML Platform, PhD Early Career)

Join Roblox as a Senior Machine Learning Engineer, where you will be a key contributor to building cutting-edge AI systems. You will work on two critical tracks: the Creator Services Machine Intelligence Team and the ML Platform Team. In the Creator Services team, you will develop scale data pipelines, train novel architectures, and optimize real-time inference for autonomous NPCs. In the ML Platform team, you will pioneer next-generation AI tooling, build and maintain core platform components, and architect scalable distributed inference systems. This role is ideal for exceptional PhD new graduates with a passion for AI and machine learning.
