Goliath Partners has exclusively partnered with a fast-growing, venture-backed frontier GenAI Research Lab that is operating at serious scale & expanding. They’re looking for a Research Engineer to help build the data behind their next-generation world models. You'll own multimodal datasets, synthetic data gen, and large-scale experimentation that directly shapes model capabilities. As a Member of Technical Staff you will: • Design multimodal datasets that directly shape what frontier world models learn • Run controlled training experiments to understand how data impacts model capabilities • Build large-scale pipelines for synthetic data generation, filtering, and quality control • Develop evaluations and benchmarks that measure meaningful model improvements Why join: • Work at the frontier of multimodal foundation models and world models • High ownership within a small, elite team operating with an exceptionally fast iteration loop • Directly shape the capabilities of next-generation AI systems from the data up Apply if interested.
