About the Role
This is a foundational opportunity to refine, personalize, and build the final capabilities and control interface of Luma’s foundation models and drive real-world value.
You’ll sit at the intersection of research, product, and partnerships, helping close the gap between generalist capability and production needs. Your mission is to make our video foundation models more expressive, controllable, and personalized – solving the “last mile” challenges demanded by top-tier creative workflows.

What You’ll Do
You will work as a fullstack researcher across modeling, data, systems, and evaluation to translate foundational capabilities into the personalized and high-fidelity tools required by top-tier creative production.
  • Controllability and Features: You will use SFT, RL, distillation, and adapter-based methods to give Luma’s models precise control and creative capabilities for high-fidelity, partner-grade workflows.
  • Personalization: You will use context management, PEFT, and preference learning to embed domain expertise and long-horizon memory into our models. You’ll ground our data engine in real-world workflows, translating usage into training and data insights that shape future models.
  • End-User Quality: You will define and drive end-user quality – setting success metrics, building user-aligned evaluations, and iterating on the model/data/evals loop to meet  strict fidelity and reliability targets in specific verticals.
  • Cross-functional Collaboration: You will partner with Product and Design to turn creative intent and user feedback into clear specs and shippable model behaviors, delivering intuitive control and dependable capabilities for users and partners.


Who You Are
  • Strong foundation in machine learning with deep experience in visual generative models (diffusion/transformers or related architectures). Ideal candidates also have a deep understanding of at least one: fine-tuning, personalization, domain adaptation, data curation, targeted distillation, interpretability, or human-feedback-driven refinement.
  • You are a product-obsessed researcher/engineer. You treat end users and partners as collaborators and enjoy solving specific “last mile” problems – not just optimizing public metrics.
  • Hands-on experience with PyTorch and large model training.

Bonus Points
  • Contributions to state-of-the-art models in image/video generation.
  • Experience collaborating with creative partners (VFX, animation, film, design tools).
  • Track record building workflows/tools that materially improve iteration speed and evaluation rigor.
  • Familiarity with large-scale training infrastructure and distributed systems (Ray, Slurm, Kubernetes).
Compensation
The base pay range for this role is $187,500 – $395,000 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.
