Senior Machine Learning Engineer, GenAI Data

Roblox is a platform that empowers a global community to create and connect through immersive digital experiences. They are seeking a Senior Machine Learning Engineer to architect high-scale data pipelines and collaborate with AI researchers to enhance data synthesis and evaluation for generative models.

Responsibilities:

• Architect and maintain automated pipelines for the ingestion, cleaning, and pre-processing of multi-modal datasets (video, 3D,) spanning petabytes of data
• Leverage image and video generation models to scale multi-modal synthetic datasets
• Partner with research teams to create training data for research experiments – research and implement synthetic data creation pipelines
• Build and own evaluation—automating both heuristic-based metrics and human-in-the-loop interfaces to evaluate and benchmark training datasets and in-house foundation models
• Design and optimize high-throughput, low-latency Inference APIs for internal and external consumer access
• Actively participate in literature reviews and paper reading groups to identify and implement the latest optimizations in generative modeling
• Implement monitoring pipeline health, optimizing data loading to ensure GPUs are used efficiently
