About the role

  • Our vision is to reimagine the way people come together, from anywhere in the world, and on any device.
  • For roles that are based at our headquarters in San Mateo, CA: The starting base pay for this position is as shown below.
  • The actual base pay is dependent upon a variety of job-related factors such as professional background, training, work experience, location, business needs and market demand.

Responsibilities

  • Develop Scale Data Pipelines: Design, build and maintain robust data pipelines to collect complex 3D game states and real-time player actions across the platform.
  • Optimize Real-Time Inference: Engineer high-performance model inference solutions to support the seamless deployment of 10s to 100s of autonomous NPCs in real-time environments.
  • Build and maintain core platform components: Serving Layer, Model Registry, Pipeline Orchestrator, and Training/Inference control planes.
  • Design great developer experiences (paved-road templates, tooling, visualizations) to reduce time-to-production and ensure foundational AI systems are scalable and reliable.
  • Architect and implement scalable distributed inference systems for efficiently serving LLMs and Large Recommender Models at massive scale.
  • Optimize our inference engine to serve millions of QPS at low latency.
  • Conduct deep, low-level performance analysis and optimize ML models (using techniques like continuous batching, speculative decoding, and quantization) and systems on GPU architectures to maintain peak performance and stability.
  • The Machine Intelligence team is building an NPC system that can (1) play any Roblox game and (2) perform real-time inference efficiently enough to support deployment to all Roblox players.
  • Design, build and maintain robust data pipelines to collect complex 3D game states and real-time player actions across the platform.
  • Engineer high-performance model inference solutions to support the seamless deployment of 10s to 100s of autonomous NPCs in real-time environments.

Requirements

  • Experience with novel datasets, and building real-world agentic applications.

Compensation

  • $196,750 - $243,290 USD
  • Therefore, in some circumstances, the actual salary could fall outside of this expected range.
  • This pay range is subject to change and may be modified in the future.
  • Annual Salary Range

Benefits

  • The AI Platform team is a foundational part of this vision, supporting hundreds of ML use cases and billions of inferences daily across Discovery, Safety, Engine, and more.
  • All full-time employees are also eligible for equity compensation and for benefits as described on this page.
  • As a Senior Machine Learning Engineer, you will be a key contributor to building the cutting-edge systems that power AI at Roblox.
  • Train Novel Architectures: Solve the feature extraction across games for NPC model in a general and scalable way and drive model training speed for novel, sophisticated deep learning architectures.
