About the role
- 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.
Responsibilities
- 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.
- Develop proxy tasks and automated metrics that serve as the compass for research decisions - ensuring our models optimize for what actually matters to users, not just benchmarks.
- Research Infrastructure Build the engine for high-velocity research.
- Maintain production-research parity, ensure reproducibility, and design systems for rapid experimentation - so that novel ideas go from hypothesis to validated result as fast as possible.
- Proven ability to design and rigorously analyze experiments and to articulate complex technical concepts effectively.
Requirements
- Practical experience with distributed or high-performance computing environments, particularly managing and optimizing training runs on large-scale GPU clusters.
- Experience with low-precision training and hardware-aware optimization for next-gen clusters.
Benefits
- Who You Are A Bachelor's, Master's, or PhD degree in Computer Science, Machine Learning, Physics, or Mathematics is essential.
- What Sets You Apart (Bonus Points) A track record of publishing at top-tier venues (NeurIPS, ICML, ICLR) and a mission-driven, "first-principles" mindset.
