Research Scientist / Engineer – Foundation Model: Core Research

Job description

Where You Come In This is a rare and foundational opportunity to define the future of multimodal AI. You will be at the forefront of architecting the intelligence governing our world-simulations—the reasoning core at the heart of our world-modeling efforts. This role offers the chance to bridge frontier research with magical, shipped products like Dream Machine and Ray3, solving novel problems where no playbook exists. What You'll Do This opportunity involves both the “science” and “engineering” of research—two aspects we view as equally critical. You will work at the intersection of modeling, data, systems, and evaluation to advance the state-of-the-art in multimodal intelligence.: - Unified Modeling & Efficiency Drive the core research that powers all of Luma's products — co-designing multimodal representations, advancing core algorithms for long-context training, and establishing rigorous scaling laws to predict performance across compute budgets. - Alignment & Evaluation Close the gap between training loss and user experience. Develop proxy tasks and automated metrics that serve as the compass for research decisions — ensuring our models optimize for what actually matters to us...
