About the Role

The VLA Core team builds the base vision-language-action model the whole company runs on, covering pre-training, world models and RL. In this role, you will use reinforcement learning, in simulation and on real hardware, to turn that model into high-performing, robust manipulation policies. This is a senior individual contributor role with no management track. Robotics experience is not required; strong RL in any domain is what matters. The team is research-adjacent, but the output is policies that work on the robot.

Responsibilities

  • Train language- and vision-conditioned manipulation policies with RL, in simulation and in the real world.
  • Build challenging and diverse suites of manipulation tasks in simulation.
  • Work with Teleoperations to collect trajectories in simulation for behaviour cloning.
  • Work with Testing and Operations to set up real-world RL training pipelines.
  • Find ways to bring policies trained in simulation to the real world (sim-to-real).

Requirements

  • 3+ years building deep learning systems in industry or research, with shipped models or published work to show for it.
  • Solved real problems with RL and deep neural networks, in any domain.
  • Trained models yourself (architecture, training and inference) on at least one of: LLMs, VLMs, image or video generative models.
  • Strong Python and PyTorch or JAX.
  • Strong coding fundamentals.
  • Proactive: can take an open, messy problem and drive it without waiting for a spec.
  • Document experiments clearly and explain trade-offs crisply.
  • Working English.
