About the Role

We’re hiring Research Interns to train on the in-the-wild physical labor dataset. This is the intern version of Member of Technical Staff: you run a real research bet for about 12 weeks, not a toy project. Collection is monocular 1920×1080p 30fps, targeting 100M hours. If you have a bet on video, world models, or physical-labor data, you might as well run it here.

Responsibilities

  • Run a research bet on Build data: train, evaluate, ablate, and document findings.
  • Collaborate with technical staff, Head of Dataset & Quality, and Evals Lead to influence collection or evaluations.
  • Develop necessary training and data paths (PyTorch, dataset slices, evals) independently.
  • Engage in both research and engineering tasks; no notebook-only tracks.

Requirements

  • Progress toward a Bachelor’s, Master’s, or PhD in CS, EE, or a related field.
  • Experience training real models using PyTorch or equivalent.
  • Interest in in-the-wild physical or video data, beyond academic splits.
  • Ability to operate independently on a 12-week project.
