Research Engineer, Data Foundations

Runway is building AI to simulate the world through merging art and science. The Research Engineer, Data Foundations will own the data behind the models, designing datasets, running modeling experiments, and building the infrastructure to generate and curate data at scale. Responsibilities Design multimodal, multitask datasets that teach world models new capabilities — deciding what data to collect, generate, or curate and measuring its effect on model behaviorRun controlled training experiments to understand how data composition drives model performance across tasks and domainsBuild and operate large-scale pipelines for synthetic data generation, filtering, and quality controlDefine evaluations and benchmarks that measure whether our models are actually improving at the things that matterPartner with product and creative teams to translate target behaviors and capabilities into concrete data strategies Qualifications 4+ years of experience in machine learning, bonus points for data-ce
