About this role

Role Overview

World Labs is seeking a full-time Research Scientist in Generative Modeling to join the modeling team in San Francisco. This position is ideal for professionals with a strong background in diffusion models who want to advance spatial intelligence in a fast-paced environment.

Key Responsibilities

Design, implement, and train large-scale diffusion models dedicated to generating 3D worlds.
Develop and experiment with diffusion models to introduce novel control signals, align with aesthetic preferences, or distill for efficient inference.
Work closely with research and product teams to translate product requirements into actionable technical roadmaps.
Contribute hands-on to every phase of model development, covering data curation, experimentation, evaluation, and deployment.
Explore and integrate cutting-edge research in diffusion and generative artificial intelligence.
Serve as a key technical resource by mentoring colleagues and establishing best practices in generative modeling and machine learning engineering.

Requirements

Three or more years of experience in applied machine learning or generative modeling roles, preferably within a startup or fast-paced research setting.
Extensive practical background using machine learning frameworks like PyTorch or TensorFlow, specifically for diffusion and other generative models.
Deep expertise in at least one generative modeling domain, such as pre-training, post-training, diffusion distillation, or fine-tuning with novel conditioning signals.
Demonstrated history of publications or open-source contributions focusing on large-scale diffusion models.
Strong programming skills in Python alongside experience in GPU-accelerated computing.
Ability to communicate complex technical concepts clearly to cross-functional teams and researchers.
Comfort operating in a dynamic startup setting characterized by high ambiguity, ownership, and innovation.

Nice to Have

Contributions to open-source projects related to computer vision, graphics, or machine learning.
Familiarity with large-scale training infrastructure, including distributed training environments and multi-node GPU clusters.
Experience deploying machine learning models into production environments.
Prior involvement in leading or developing state-of-the-art, large-scale generative models.
