Founding Research Scientist at stealth physical AI startup

Every major robotics company is privately struggling with the data bottleneck; this stealth startup is building the infrastructure to fix it. We are looking for a Founding Research Scientist to own the entire research stack and move from 'researcher at a big lab' to the person who built the function from scratch. If you have experience training real-world manipulation policies on physical hardware and want a founding seat with significant equity in San Francisco, this is the most impactful role in the physical AI sector today.

What you'll do

What you will do

  • Train and evaluate real-world robot manipulation policies using imitation learning, diffusion policies, or vision-language-action models.
  • Build the end-to-end data-to-policy validation pipeline to ensure high-quality tactile and interaction data translates to performance.
  • Work alongside hardware and software teams to define the research roadmap and iterate on differentiated data collection methods.

Who you are

Who this is a fit for

  • Proven track record training manipulation policies on physical hardware, focusing on dexterous manipulation or tactile sensing.
  • PhD from a top-tier robotics laboratory or extensive research experience at a leading organization specializing in physical foundation models.
  • Strong desire to work in an early-stage, hands-on individual contributor role with the ambition to build a research function from scratch.

Why this role

Why this role is remarkable

  • Rare opportunity to join as a founding member with minority co-founder level equity and full ownership of the research agenda.
  • Work at the critical intersection of robotics and data infrastructure, solving the primary bottleneck preventing the scaling of physical AI.
  • Collaborate directly with a technical founding team in a high-autonomy environment where you set the research direction and validation strategy.
