Research Engineer / Scientist (3d Tech Lead)

World Labs World Labs · AI Frontier · San Francisco, CA · 3DGM

World Labs is seeking a Tech Lead for 3D Modeling & Reconstruction to set technical direction and drive execution for their core 3D modeling efforts. This role involves leading the design and implementation of state-of-the-art 3D modeling systems, driving innovation in modern 3D modeling approaches, and guiding architectural decisions around 3D representations, training pipelines, and inference systems. The role also includes leading and mentoring a team, owning end-to-end execution, and collaborating with cross-functional partners.

What you'd actually do

  1. Set the technical vision and roadmap for 3D modeling and reconstruction, balancing research exploration with product-driven milestones.
  2. Lead the design and implementation of state-of-the-art 3D modeling systems, spanning geometry, appearance, and scene-level representations.
  3. Drive innovation in modern 3D modeling approaches, including learning-based and optimization-based methods, with an eye toward robustness, scalability, and real-world data.
  4. Guide architectural decisions around 3D representations, training pipelines, and inference systems, ensuring they integrate cleanly with broader 3D data and rendering platforms.
  5. Lead and mentor a small team of research scientists and/or research engineers: providing technical guidance, setting high standards, and fostering a culture of rigor and ownership.

Skills

Required

  • 8+ years of experience in 3D reconstruction, 3D modeling, computer vision, graphics, or closely related fields.
  • A strong track record of impactful contributions to the field, demonstrated through academic publications, influential open-source work, or widely deployed industry products.
  • Deep expertise in modern 3D modeling and reconstruction methods, including representation design, optimization strategies, and learning-based approaches.
  • Proven experience leading or mentoring a small team, lab, or project group, with responsibility for technical direction and delivery.
  • Strong programming skills in Python and/or C++, with experience building both research prototypes and production-quality systems.
  • Hands-on experience with machine learning frameworks and large-scale experimentation or training pipelines.
  • Solid understanding of how 3D modeling systems interface with data pipelines, rendering, and downstream applications.
  • Comfort operating in fast-moving, ambiguous environments, making high-leverage technical decisions with incomplete information.
  • High ownership mindset and a product-aware perspective: you care not just about novelty, but about reliability, performance, and impact.
  • Enjoy collaborating with senior peers across research and engineering, and raising the technical bar through example, mentorship, and clear technical communication.
