SALARY
$200,000 - $400,000
About the role
- Design and train large-scale video foundation models on diverse datasets spanning internet-scale video and robot-collected data
- Develop pretraining strategies that capture temporal dynamics, motion, and object interaction from raw video sequences
- Build models that learn transferable representations for downstream tasks such as perception, tracking, prediction, and control
- Explore architectures for video understanding and generation, including transformer-based and diffusion-based approaches
- Implement efficient data pipelines and training strategies for high-throughput video ingestion and large-scale distributed training
- Optimize model performance across compute, memory, and training efficiency constraints
- Collaborate closely with generative modeling, agent, and robot learning teams to integrate pretrained models into the autonomy stack
- Design evaluation frameworks and benchmarks to measure temporal understanding, prediction quality, and generalization
- Experience training large-scale models on video data or other high-dimensional sequential modalities
- Strong understanding of modern deep learning architectures for video, vision, or multimodal systems
- Experience with large-scale pretraining, including dataset curation, training dynamics, and scaling laws
- Proficiency in Python and deep learning frameworks such as PyTorchExperience working with distributed training systems and large GPU clusters
- Strong experimental rigor and ability to iterate quickly on model design and training strategies
- Solid software engineering skills and ability to build scalable, reliable systems
- Ability to operate independently and drive ambiguous, high-impact research directions
- Bonus Qualifications
- Experience working on frontier video models or multimodal foundation models
- Background in video diffusion, autoregressive video modeling, or world models
- Experience at leading AI labs such as OpenAI, Google DeepMind, Google, ByteDance, Midjourney, or Adobe
- Experience with large-scale dataset construction and filtering for video pretraining
- Familiarity with robotics, embodied AI, or learning from egocentric / first-person video
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
