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 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.

Who You Are

  • A Bachelor's, Master's, or Ph D degree in Computer Science, Machine Learning, Physics, or Mathematics is essential.
  • A 'first-principles' intuition for scaling. You don't just follow the literature; you understand why certain architectures succeed or fail at scale.
  • Fluent in the language of frontier AI. You see research and engineering as a single, unified discipline.
  • Proven ability to design and rigorously analyze experiments and to articulate complex technical concepts effectively.
  • Practical experience with distributed or high‑performance computing environments, particularly managing and optimizing training runs on large‑scale GPU clusters.
  • What Sets You Apart (Bonus Points)
  • A track record of publishing at top‑tier venues (Neur IPS, ICML, ICLR) and a mission‑driven, "first-principles" mindset.
  • Infrastructure Expertise: Proven ability to build and lead research infrastructure for technical teams, ensuring production‑research parity.
  • Engineering

Excellence: Strong commitment to software engineering best practices, including optimizing for code readability and reusability, implementing comprehensive unit and integration tests, and maintaining high documentation standards (necessary docstrings).

  • Experience with low‑precision training and hardware‑aware optimization for next‑gen clusters.

Compensation

The base pay range for this role is $250,000 – $450,000 per year.

About Luma

Luma’s mission is to build unified general intelligence that can generate, understand, and operate in the physical world.

We believe that multimodality is critical for intelligence.

To go beyond language models and build more aware, capable and useful systems, the next step function change will come from vision.

So, we are working on training and scaling up multimodal foundation models for systems that can see and understand, show and explain, and eventually interact with our world to effect change.
