Job summary

Persona AI is building humanoid robots for demanding environments, collecting multimodal data from egocentric video, IMU and other sensors to train robust models.

The AI Data Engineer will architect scalable preprocessing systems, quantify grasp dynamics from force signals, and reconstruct occluded hand poses to produce high-quality training assets for robots. This role sits in a fast-growing robotics software team.

Qualifications

• MS or PhD in Computer Science, Data Engineering, Machine Learning, Robotics, or a related field.
• Experience with Python and PyTorch for multimodal datasets.
• Experience processing force-time-series and video data.

Responsibilities

• Design cross-modal validation systems aligning video, proprioception, force/haptic signals, and language annotations.
• ork hand-tracking, 3D reconstruction, and pose-tracking; retarget demonstrations to robot trajectories.
• Implement data augmentation to expand expert trajectories and improve model robustness.
• Build end-to-end multimodal data pipelines turning raw recordings into training-ready datasets.
• Develop tooling to query, visualize, and audit datasets and curation rules.
