About the role
About Build AI
Build AI is the data hyperscaler for Physical AI. We co-design hardware, collection, infrastructure, and research to scale the physical labor dataset orders of magnitude faster than anyone in the world.
Job Summary
We’re hiring Research Interns to train on the physical labor dataset. 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.
Key Responsibilities
Run a research bet on Build data: train, evaluate, ablate, and write down what the data actually taught
Work with researchers, dataset, and evals so the internship changes collection or evals, not only a slide
Build the training and data path you need (PyTorch, dataset slices, evals) instead of waiting for a platform team
Cover research and engineering. There is no intern track that is only notebooks
You may be a good fit if you have (Must-have qualifications)
Progress toward a Bachelor’s, Master’s, or PhD (preferred) in CS, EE, or a related field
You have trained real models (course, lab, open source, or a paper). PyTorch or equivalent
You want in-the-wild physical or video data, not only academic splits
You can operate independently on a 12-week bet
You will be in San Francisco, in person
Strong candidates may also have experience with (Nice-to-have qualifications)
Video, world models, robotics, or multimodal training
Egocentric or in-the-wild video
Large-scale training, dataset curation, or distributed GPU work
Publication at a top conference (CVPR, NeurIPS, ICML, ICLR, RSS, CoRL, or equivalent)
A paper, open-source model, or project that changed what you did next
Benefits

How we're different
Build believes in the Bitter Lesson. By taking a general approach of learning from humans, our addressable market is all physical labor.
We are a fully in-person team in San Francisco (Financial District) and Shenzhen (Nanshan), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both and work across disciplines as needed.
Build AI is an equal opportunity employer. We review every application. If you do not meet every bullet, still apply. Questions: research@build.ai
