Robotics AI Foundation Scientist (Large-Scale Pretraining)

Generalist; Medford Hillside (MA); On-site; USD 180,000 - 250,000; Full time

Job summary

Generalist is building the base intelligence layer for robotics by training large-scale robot foundation models on multimodal data, spanning video, proprioception, action traces, language, and more.

You will design and run core training efforts to enable general capabilities across embodiments, tasks, and environments, working with teams across ML Infra and Systems to optimize throughput and reliability.

Qualifications

• Have worked on large-scale ML systems with senior/staff (L6+) experience.
• Have deep experience training large transformer or diffusion models at scale (e.g. generative models).
• Have led or significantly contributed to multi-node, multi-GPU distributed training efforts.
• Have worked on scaling laws, optimization dynamics, and large-model failure modes.
• Have strong PyTorch fundamentals and comfort debugging at every layer of the stack.
• Care about both empirical rigor and raw iteration speed.
• Are excited about building general-purpose robot intelligence from first principles.

Responsibilities

• Designing and executing large-scale pretraining runs for robot foundation models (transformer- and diffusion-based architectures)
• Defining model architectures, objectives, and training curricula across multimodal robotic data (vision, action, state, language)
• Developing scalable data mixtures and sampling strategies across petabyte-scale datasets
• Guiding data collection operations towards new directions, as well as sourcing new datasets
• Running ablations to understand scaling laws, data quality effects, and architecture tradeoffs
• Collaborating closely with ML Infra and Systems to push cluster utilization, throughput, and reliability
• Turning raw robotic interaction data into generalizable model capabilities
