About the Role

The VLA Core team builds the base vision-language-action model that the entire manipulation pipeline depends on. This involves deep learning at scale, training models from scratch on multi-embodiment trajectory corpora and internet-scale video, with real deployment constraints. The model must fit and run on a real robot. This is a senior individual contributor role with no management track, focused on research-adjacent output for real robots.

Responsibilities

  • Pre-train base models on a diverse multi-embodiment corpus of trajectories.
  • Fine-tune policies to excel at specific tasks and explore synthetic data.
  • Post-train policies with behaviour cloning and RL, and own the full loop from data to deployment.
  • Partner with the Data Collection team to specify data requirements, identify failure modes, and ensure diversity and coverage.
  • Run pre-, mid-, and post-training on the VLA stack; explore new modalities and architecture changes.
  • Build and maintain continuous pipelines for ingesting synthetic data and teleop logs, versioning them, applying weak-supervision labelling, curating balanced datasets, and automatically surfacing fresh failure cases into retraining.
  • Work with MLOps and Data Platform teams to scale distributed training and optimize models for real-time edge inference on the robot.
  • Design and train multimodal, action-conditioned world models (video, state, action and language) using diffusion-based and transformer architectures.
  • Build video prediction and dynamics models that stay physically consistent over long horizons, including contact-rich manipulation, serving as pretrained priors for VLA policies.
  • Develop learned-simulator evaluation to score candidate policies offline, predict real-world success rates before deployment, and roll out policy futures for safety review and planning.
  • Generate synthetic rollouts and counterfactual experience (rare events, cross-platform and sim-to-real transfer) and measure their effect on downstream task performance.
  • Build data pipelines that turn fleet telemetry, teleoperation logs, and internet-scale video into training corpora.
  • Run scaling and ablation studies on architecture, data mixture, and context length.

Requirements

  • 3+ years building deep learning systems in industry or research, with shipped models or published work.
  • Deep hands-on experience with at least one of: LLMs, VLMs, image or video generative models (architecture, training and inference).
  • For the World Models track: diffusion models, autoregressive transformers, latent-variable models, or video prediction.
  • Experience training models yourself: pre-training runs, distributed infrastructure.
  • Experience with deep learning infrastructure: streaming datasets, checkpointing and state management, distributed training strategies, debugging numerics and training instabilities.
  • Strong Python and PyTorch or JAX.
  • Strong coding fundamentals.
  • Empirical rigor: careful evaluations, honest baselines, clear experiment docs, crisp communication of trade-offs.
  • Proactive: ability to take an open, messy problem and drive it without waiting for a spec.
  • Working English.
